Description: ===============================================
        django-fobi
        ===============================================
        `django-fobi` (later on named just `fobi`) is a customisable, modular,
        user- and developer- friendly form generator/builder application for Django. 
        With `fobi` you can build Django forms using an intiutive GUI, save or
        mail posted form data. API allows you to build your own form elements and
        form handlers (mechanisms for handling the submitted form data).
        
        Prerequisites
        ===============================================
        - Django 1.5, 1.6, 1.7
        - Python >= 2.6.8, 2.7.*, 3.3.*
        
        Note, that Django 1.7 is not yet proclaimed to be flawlessly supported!
        
        Key concepts
        ===============================================
        - Each form consists of elements. Form elements are divided
          into two groups:
        
          - (a) form fields (input field, textarea, hidden field, file field, etc.).
          - (b) content (presentational) elements (text, image, embed video, etc.).
        
        - Number of form elements is not limited.
        - Each form may contain handlers. Handler processes the form data (for example,
          saves it or mails it). Number of the handlers is not limited.
        - Both form elements and form handlers are made with Django permission system 
          in mind.
        - As an addition to form handlers, form callbacks are implemented. Form 
          callbacks are fired on various stages of pre- and post-processing the form
          data (on POST). Form callbacks do not make use of permission system (unless
          you intentionally do so in the code of your callback) and are fired for all 
          forms (unlike form handlers, that are executed only if assigned).
        - Each plugin (form element or form handler) or a callback - is a Django
          micro-app.
        
        Note, that Fobi does not require django-admin and administrative rights/
        permissions to access the UI, although almost seamless integration with
        django-admin is implemented through the ``simple`` theme.
        
        Main features and highlights
        ===============================================
        - User-friendly GUI to quickly build forms.
        - Large variety of `Bundled form element plugins`_. Most of the Django fields
          are supported. `HTML5 fields`_ are supported as well.
        - Anti-spam solutions like `CAPTCHA
          <https://github.com/barseghyanartur/django-fobi/tree/stable/src/fobi/contrib/plugins/form_elements/security/captcha>`_,
          `ReCAPTCHA
          <https://github.com/barseghyanartur/django-fobi/tree/stable/src/fobi/contrib/plugins/form_elements/security/recaptcha>`_
          or `Honeypot
          <https://github.com/barseghyanartur/django-fobi/tree/stable/src/fobi/contrib/plugins/form_elements/security/honeypot>`_
          come out of the box (CAPTCHA and ReCAPTCHA do require additional third-party
          apps to be installed).
        - In addition to standard form elements, there are cosmetic (presentational)
          form elements (for adding a piece of text, image or a embed video)
          alongside standard form elements.
        - Data handling in plugins (form handlers). Save the data, mail it to some
          address or repost it to some other endpoint. See the
          `Bundled form handler plugins`_ for more information.
        - Developer-friendly API, which allows to edit existing or build new form 
          fields and handlers without touching the core.
        - Support for custom user model.
        - `Theming`_. There are 3 ready to use `Bundled themes`_: Bootstrap 3,
          Foundation 5 and Simple (in style of Django admin).
        - Implemented `integration with FeinCMS
          <https://github.com/barseghyanartur/django-fobi/tree/stable/src/fobi/contrib/apps/feincms_integration>`_
          (in a form of a FeinCMS page widget).
        - Implemented `integration with DjangoCMS
          <https://github.com/barseghyanartur/django-fobi/tree/stable/src/fobi/contrib/apps/djangocms_integration>`_
          (in a form of a DjangoCMS page plugin).
        - Implemented `integration with Mezzanine
          <https://github.com/barseghyanartur/django-fobi/tree/stable/src/fobi/contrib/apps/mezzanine_integration>`_
          (in a form of a Mezzanine page).
        - Reordering of form elements using drag-n-drop.
        - Data export (`db_store 
          <https://github.com/barseghyanartur/django-fobi/tree/stable/src/fobi/contrib/plugins/form_handlers/db_store>`_
          form handler plugin) into XLS/CSV format.
        
        Roadmap
        ===============================================
        Some of the upcoming/in-development features/improvements are:
        
        - Form importers (and as a part of it - MailChimp integration,
          which would allow to import forms from MailChimp into Fobi using
          a user-friendly wizard).
        - Fieldsets.
        
        See the `TODOS <https://raw.githubusercontent.com/barseghyanartur/django-fobi/master/TODOS.rst>`_
        for the full list of planned-, pending- in-development- or to-be-implemented
        features.

        - `PythonHosted <http://pythonhosted.org/django-fobi/#screenshots>`_
        - `ReadTheDocs <http://django-fobi.readthedocs.org/en/latest/#screenshots>`_
        
        Live demo
        -----------------------------------------------
        See the `live demo app <https://django-fobi.herokuapp.com/>`_ on Heroku.
        
        Credentials:
        
        - username: test_user
        - password: test_user
        
        Run demo locally
        -----------------------------------------------
        In order to be able to quickly evaluate the `Fobi`, a demo app (with a quick
        installer) has been created (works on Ubuntu/Debian, may work on other Linux
        systems as well, although not guaranteed). Follow the instructions below for
        having the demo running within a minute.
        
        Grab the latest `django_fobi_example_app_installer.sh`:
        
        .. code-block:: none
        
            $ wget https://raw.github.com/barseghyanartur/django-fobi/stable/examples/django_fobi_example_app_installer.sh
        
        Assign execute rights to the installer and run the
        `django_fobi_example_app_installer.sh`:
        
        .. code-block:: none
        
            $ chmod +x django_fobi_example_app_installer.sh
            $ ./django_fobi_example_app_installer.sh
        
        Open your browser and test the app.
        
        Dashboard:
        
        - URL: http://127.0.0.1:8001/fobi/
        - Admin username: test_admin
        - Admin password: test
        
        Django admin interface:
        
        - URL: http://127.0.0.1:8001/admin/
        - Admin username: test_admin
        - Admin password: test
        
        If quick installer doesn't work for you, see the manual steps on running the
        `example project
        <https://github.com/barseghyanartur/django-fobi/tree/stable/examples>`_.

        2. Add `fobi` to ``INSTALLED_APPS`` of the your projects' Django settings. 
           Furthermore, all themes and plugins to be used, shall be added to the
           ``INSTALLED_APPS`` as well.
        
        .. code-block:: python
        
            INSTALLED_APPS = (
                # ...
                # Fobi core
                'fobi',
        
                # Fobi themes
                'fobi.contrib.themes.bootstrap3', # Bootstrap 3 theme
                'fobi.contrib.themes.foundation5', # Foundation 5 theme
                'fobi.contrib.themes.simple', # Simple theme
        
                # Fobi form elements - fields
                'fobi.contrib.plugins.form_elements.fields.boolean',
                'fobi.contrib.plugins.form_elements.fields.date',
                'fobi.contrib.plugins.form_elements.fields.datetime',
                'fobi.contrib.plugins.form_elements.fields.email',
                'fobi.contrib.plugins.form_elements.fields.file',
                'fobi.contrib.plugins.form_elements.fields.hidden',
                'fobi.contrib.plugins.form_elements.fields.integer',
                'fobi.contrib.plugins.form_elements.fields.password',
                'fobi.contrib.plugins.form_elements.fields.radio',
                'fobi.contrib.plugins.form_elements.fields.select',
                'fobi.contrib.plugins.form_elements.fields.select_model_object',
                'fobi.contrib.plugins.form_elements.fields.select_multiple',
                'fobi.contrib.plugins.form_elements.fields.text',
                'fobi.contrib.plugins.form_elements.fields.textarea',
                'fobi.contrib.plugins.form_elements.fields.url',
        
                # Fobi form elements - content elements
                'fobi.contrib.plugins.form_elements.test.dummy',
                'fobi.contrib.plugins.form_elements.content.content_image',
                'fobi.contrib.plugins.form_elements.content.content_text',
                'fobi.contrib.plugins.form_elements.content.content_video',
        
                # Form handlers
                'fobi.contrib.plugins.form_handlers.db_store',
                'fobi.contrib.plugins.form_handlers.http_repost',
                'fobi.contrib.plugins.form_handlers.mail',
        
                # Other project specific apps
                'foo', # Test app
                # ...
            )
        
        3. Make appropriate changes to the ``TEMPLATE_CONTEXT_PROCESSORS`` of the your
           projects' Django settings.
        
        And the following to the context processors.
        
        .. code-block:: python
        
            TEMPLATE_CONTEXT_PROCESSORS = (
                # ...
                "fobi.context_processors.theme".
                # ...
            )
        
        Make sure that ``django.core.context_processors.request`` is in
        ``TEMPLATE_CONTEXT_PROCESSORS`` too.
        
        4. Configure URLs
        
        Add the following line to urlpatterns of your urls module.
        
        .. code-block:: python
        
            # View URLs
            url(r'^fobi/', include('fobi.urls.view')),
        
            # Edit URLs
            url(r'^fobi/', include('fobi.urls.edit')),
        
        View URLs are put separately from edit URLs in order to make it possible
        to prefix the edit URLs differently. For example, if you're using the
        "Simple" theme, you would likely want to prefix the edit URLs with "admin/"
        so that it looks more like django-admin.
        
        Creating a new form element plugin
        ===============================================
        Form element plugins represent the elements of which the forms is made:
        Inputs, checkboxes, textareas, files, hidden fields, as well as pure
        presentational elements (text or image). Number of form elements in a form
        is not limited.
        
        Presentational form elements are inherited from ``fobi.base.FormElementPlugin``.
        
        The rest (real form elements, that are supposed to have a value)
        are inherited from ``fobi.base.FormFieldPlugin``.
        
        You should see a form element plugin as a Django micro app, which could have
        its' own models, admin interface, etc.
        
        Fobi comes with several bundled form element plugins. Do check the source code
        as example.
        
        Let's say, you want to create a textarea form element plugin.
        
        There are several properties, each textarea should have. They are:
        
        - `label` (string): HTML label of the textarea.
        - `name` (string): HTML name of the textarea.
        - `initial` (string): Initial value of the textarea.
        - `required` (bool): Flag, which tells us whether the field is required or
          optional.
        
        Let's name that plugin `sample_textarea`. The plugin directory should then have
        the following structure.
        
        .. code-block:: none
        
            path/to/sample_textarea/
            ├── __init__.py
            ├── fobi_form_elements.py # Where plugins are defined and registered
            ├── forms.py # Plugin configuration form
            └── widgets.py # Where plugins widgets are defined
        
        Form element plugins should be registered in "fobi_form_elements.py" file. Each
        plugin module should be put into the ``INSTALLED_APPS`` of your Django
        projects' settings.
        
        In some cases, you would need plugin specific overridable settings (see
        ``fobi.contrib.form_elements.fields.content.content_image`` plugin as an
        example). You are advised to write your settings in such a way, that variables
        of your Django project settings module would have `FOBI_PLUGIN_` prefix.
        
        Define and register the form element plugin
        -----------------------------------------------
        Step by step review of a how to create and register a plugin and plugin
        widgets. Note, that Fobi autodiscovers your plugins if you place them into a
        file named `fobi_form_elements.py` of any Django app listed in
        ``INSTALLED_APPS`` of your Django projects' settings module.
        
        path/to/sample_textarea/fobi_form_elements.py
        ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
        A single form element plugin is registered by its' UID.
        
        Required imports.
        
        .. code-block:: python
        
            from django import forms
            from fobi.base import FormFieldPlugin, form_element_plugin_registry
            from path.to.sample_textarea.forms import SampleTextareaForm
        
        Defining the Sample textarea plugin.
        
        .. code-block:: python
        
            class SampleTextareaPlugin(FormFieldPlugin):
                uid = "sample_textarea"
                name = "Sample Textarea"
                form = SampleTextareaForm
                group = "Samples" # Group to which the plugin belongs to
                
                def get_form_field_instances(self):
                    kwargs = {
                        'required': self.data.required,
                        'label': self.data.label,
                        'initial': self.data.initial,
                        'widget': forms.widgets.Textarea(attrs={})
                    }
        
                    return [(self.data.name, forms.CharField, kwargs),]
        
        Registering the ``SampleTextareaPlugin`` plugin.
        
        .. code-block:: python
        
            form_element_plugin_registry.register(SampleTextareaPlugin)
        
        Note, that in case you want to define a pure presentational element, make use
        of ``fobi.base.FormElementPlugin`` for subclassing, instead of
        ``fobi.base.FormFieldPlugin``.
        See the source of the content plugins
        (fobi.contrib.plugins.form_elements.content) as a an example.
        
        For instance, the ``captcha`` and ``honeypot`` fields are implemented
        as form elements (subclasses the ``fobi.base.FormElementPlugin``). The
        ``db_store`` form handler plugin does not save the form data of
        those elements. If you want the form element data to be saved, do inherit
        from ``fobi.base.FormFieldPlugin``.
        
        Hidden form element plugins, should be also having set the ``is_hidden``
        property to True. By default it's set to False. That makes the hidden
        form elements to be rendered using as ``django.forms.widgets.TextInput``
        widget in edit mode. In the view mode, the original widget that you
        assigned in your form element plugin would be used.
        
        There might be cases, when you need to do additional handling of the data upon
        the successful form submittion. In such cases, you will need to define a 
        ``submit_plugin_form_data`` method in the plugin, which accepts the 
        following arguments:
        
        - `form_entry` (fobi.models.FormEntry): Form entry, which is being submitted.
        - `request` (django.http.HttpRequest): The Django HTTP request.
        - `form` (django.forms.Form): Form object (a valid one, which contains 
          the ``cleaned_data`` attribute).
          
        Example (taken from fobi.contrib.plugins.form_elements.fields.file):
        
        .. code-block:: python
        
            def submit_plugin_form_data(self, form_entry, request, form):
                # Get the file path
                file_path = form.cleaned_data.get(self.data.name, None)
                if file_path:
                    # Handle the upload
                    saved_file = handle_uploaded_file(FILES_UPLOAD_DIR, file_path)
                    # Overwrite ``cleaned_data`` of the ``form`` with path to moved
                    # file.
                    form.cleaned_data[self.data.name] = "{0}{1}".format(
                        settings.MEDIA_URL, saved_file
                        )
        
                # It's critically important to return the ``form`` with updated
                # ``cleaned_data``
                return form
        
        In the example below, the original form is being modified. If you don't want
        the original form to be modified, do not return anything.
        
        Check the file form element plugin
        (fobi.contrib.plugins.form_elements.fields.file) for complete example.
        
        path/to/sample_textarea/forms.py
        ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
        Why to have another file for defining forms? Just to keep the code clean and
        less messy, although you could perfectly define all your plugin forms in the
        module `fobi_form_elements.py`, it's recommended to keep it separate.
        
        Take into consideration, that `forms.py` is not an autodiscovered file pattern.
        All your form element plugins should be registered in modules named
        `fobi_form_elements.py`.
        
        Required imports.
        
        .. code-block:: python
        
            from django import forms
            from fobi.base import BasePluginForm
        
        Form for for ``SampleTextareaPlugin`` form element plugin.
        
        .. code-block:: python
        
            class SampleTextareaForm(forms.Form, BasePluginForm):
                plugin_data_fields = [
                    ("name", ""),
                    ("label", ""),
                    ("initial", ""),
                    ("required", False)
                ]
        
            name = forms.CharField(label="Name", required=True)
            label = forms.CharField(label="Label", required=True)
            initial = forms.CharField(label="Initial", required=False)
            required = forms.BooleanField(label="Required", required=False)
        
        Note that although it's not being checked in the code, but for form 
        field plugins the following fields should be present in the plugin
        form (``BasePluginForm``) and the form plugin (``FormFieldPlugin``):
        
        - name
        
        In some cases, you might want to do something with the data
        before it gets saved. For that purpose, ``save_plugin_data`` method
        has been introduced.
        
        See the following `example
        <https://github.com/barseghyanartur/django-fobi/blob/stable/src/fobi/contrib/plugins/form_elements/content/image/forms.py>`_.
        
        .. code-block:: python
        
            def save_plugin_data(self, request=None):
                """
                Saving the plugin data and moving the file.
                """
                file_path = self.cleaned_data.get('file', None)
                if file_path:
                    saved_image = handle_uploaded_file(IMAGES_UPLOAD_DIR, file_path)
                    self.cleaned_data['file'] = saved_image
        
        path/to/sample_textarea/widgets.py
        ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
        Required imports.
        
        .. code-block:: python
        
            from fobi.base import FormElementPluginWidget
        
        Defining the base plugin widget.
        
        .. code-block:: python
        
            class BaseSampleTextareaPluginWidget(FormElementPluginWidget):
                # Same as ``uid`` value of the ``SampleTextareaPlugin``.
                plugin_uid = "sample_textarea"
        
        path/to/sample_layout/fobi_form_elements.py
        ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
        Register in the registry (in some module which is for sure to be loaded; it's
        handy to do it in the theme module).
        
        Required imports.
        
        .. code-block:: python
        
            from fobi.base import form_element_plugin_widget_registry
            from path.to.sample_textarea.widgets import BaseSampleTextareaPluginWidget
        
        Define the theme specific plugin.
        
        .. code-block:: python
        
            class SampleTextareaPluginWidget(BaseSampleTextareaPluginWidget):
                theme_uid = 'bootstrap3' # Theme for which the widget is loaded
                media_js = ['sample_layout/js/fobi.plugins.form_elements.sample_textarea.js',]
                media_css = ['sample_layout/css/fobi.plugins.form_elements.sample_textarea.css',]
        
        Register the widget.
        
        .. code-block:: python
        
            form_element_plugin_widget_registry.register(SampleTextareaPluginWidget)
        
        Form element plugin final steps
        ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
        Now, that everything is ready, make sure your plugin module is added to
        ``INSTALLED_APPS``.
        
        .. code-block:: python
        
            INSTALLED_APPS = (
                # ...
                'path.to.sample_textarea',
                # ...
            )
        
        Afterwards, go to terminal and type the following command.
        
        .. code-block:: none
        
            $ ./manage.py fobi_sync_plugins
        
        If your HTTP server is running, you would then be able to see the new plugin
        in the edit form interface.
        
        Dashboard URL: http://127.0.0.1:8000/fobi/
        
        Note, that you have to be logged in, in order to use the dashboard. If your
        new plugin doesn't appear, set the ``FOBI_DEBUG`` to True in your Django's
        local settings module, re-run your code and check console for error
        notifications.
        
        Creating a new form handler plugin
        ===============================================
        Form handler plugins handle the form data. Fobi comes with several bundled
        form handler plugins, among which is the ``db_store`` and ``mail`` plugins,
        which are responsible for saving the submitted form data into the database
        and mailing the data to recipients specified. Number of form handlers in a
        form is not limited. Certain form handlers are not configurable (for
        example the ``db_store`` form handler isn't), while others are (``mail``,
        ``http_repost``).
        
        You should see a form handler as a Django micro app, which could have its' own
        models, admin interface, etc.
        
        As said above, Fobi comes with several bundled form handler plugins. Do check
        the source code as example.
        
        Define and register the form handler plugin
        -----------------------------------------------
        Let's name that plugin `sample_mail`. The plugin directory should then have
        the following structure.
        
        .. code-block:: none
        
            path/to/sample_mail/
            ├── __init__.py
            ├── fobi_form_handlers.py # Where plugins are defined and registered
            └── forms.py # Plugin configuration form
        
        Form handler plugins should be registered in "fobi_form_handlers.py" file.
        Each plugin module should be put into the ``INSTALLED_APPS`` of your Django
        projects' settings.
        
        path/to/sample_mail/fobi_form_handlers.py
        ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
        A single form handler plugin is registered by its' UID.
        
        Required imports.
        
        .. code-block:: python
        
            import json
            from django.core.mail import send_mail
            from fobi.base import FormHandlerPlugin, form_handler_plugin_registry
            from path.to.sample_mail.forms import SampleMailForm
        
        Defining the Sample mail handler plugin.
        
        .. code-block:: python
        
            class SampleMailHandlerPlugin(FormHandlerPlugin):
                uid = "sample_mail"
                name = _("Sample mail")
                form = SampleMailForm
        
                def run(self, form_entry, request, form):
                    send_mail(
                        self.data.subject,
                        json.dumps(form.cleaned_data),
                        self.data.from_email,
                        [self.data.to_email],
                        fail_silently = True
                        )
        
        Some form handlers are configurable, some others not. In order to
        have a user friendly way of showing the form handler settings, what's
        sometimes needed, a ``plugin_data_repr`` method has been introducd.
        Simplest implementation of it would look as follows:
        
        .. code-block:: python
        
            def plugin_data_repr(self):
                """
                Human readable representation of plugin data.
        
                :return string:
                """
                return self.data.__dict__
        
        path/to/sample_mail/forms.py
        ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
        If plugin is configurable, it has configuration data. A single form may have
        unlimited number of same plugins. Imagine, you want to have different subjects
        and additional body texts for different user groups. You could then assign two
        form handler ``mail`` plugins to the form. Of course, saving the posted form
        data many times does not make sense, but it's up to the user. So, in case if
        plugin is configurable, it should have a form.
        
        Why to have another file for defining forms? Just to keep the code clean and
        less messy, although you could perfectly define all your plugin forms in the
        module `fobi_form_handlers.py`, it's recommended to keep it separate.
        
        Take into consideration, that `forms.py` is not an autodiscovered file pattern.
        All your form handler plugins should be registered in modules named
        `fobi_form_handlers.py`.
        
        Required imports.
        
        .. code-block:: python
        
            from django import forms
            from django.utils.translation import ugettext_lazy as _
            from fobi.base import BasePluginForm
        
        Defining the form for Sample mail handler plugin.
        
        .. code-block:: python
        
            class MailForm(forms.Form, BasePluginForm):
                plugin_data_fields = [
                    ("from_name", ""),
                    ("from_email", ""),
                    ("to_name", ""),
                    ("to_email", ""),
                    ("subject", ""),
                    ("body", ""),
                ]
        
                from_name = forms.CharField(label=_("From name"), required=True)
                from_email = forms.EmailField(label=_("From email"), required=True)
                to_name = forms.CharField(label=_("To name"), required=True)
                to_email = forms.EmailField(label=_("To email"), required=True)
                subject = forms.CharField(label=_("Subject"), required=True)
                body = forms.CharField(label=_("Body"), required = False,
                                       widget=forms.widgets.Textarea)
        
        After the plugin has been processed, all its' data is available in a
        ``plugin_instance.data`` container (for example,
        ``plugin_instance.data.subject`` or ``plugin_instance.data.from_name``).
        
        Prioritise the excecution order
        ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
        Some form handlers shall be executed prior others. A good example of such, is
        a combination of "mail" and "db_save" form handlers for the form. In case of
        large files posted, submittion of form data would fail if "mail" plugin would
        be executed after "db_save" has been executed. That's why it's possible to
        prioritise that ordering in a ``FOBI_FORM_HANDLER_PLUGINS_EXECUTION_ORDER``
        setting variable.
        
        If not specified or left empty, form handler plugins would be ran in the order
        of discovery. All form handler plugins that are not listed in the
        ``FORM_HANDLER_PLUGINS_EXECUTION_ORDER``, would be ran after the plugins that
        are mentioned there.
        
        .. code-block:: python
        
            FORM_HANDLER_PLUGINS_EXECUTION_ORDER = (
                'http_repost',
                'mail',
                # The 'db_store' is left out intentionally, since it should
                # be the last plugin to be executed.
            )
        
        Form handler plugin custom actions
        ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
        By default, a single form handler plugin has at least a "delete" action.
        If plugin is configurable, it gets an "edit" action as well.
        
        For some of your plugins, you may want to register a custom action. For
        example, the "db_store" plugin does have one, for showing a link to
        a listing page with saved form data for the form given.
        
        For such cases, define a ``custom_actions`` method in your form handler
        plugin. That method shall return a list of triples. In each triple,
        first value is the URL, second value is the title and the third value
        is the icon of the URL.
        
        The following example is taken from the "db_store" plugin.
        
        .. code-block:: python
        
            def custom_actions(self):
                """
                Adding a link to view the saved form enties.
        
                :return iterable:
                """
                return (
                    (
                        reverse('fobi.contrib.plugins.form_handlers.db_store.view_saved_form_data_entries'),
                        _("View entries"),
                        'glyphicon glyphicon-list'
                    ),
                )
        
        Form handler plugin final steps
        ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
        Do not forget to add the form handler plugin module to ``INSTALLED_APPS``.
        
        .. code-block:: python
        
            INSTALLED_APPS = (
                # ...
                'path.to.sample_mail',
                # ...
            )
        
        Afterwards, go to terminal and type the following command.
        
        .. code-block:: none
        
            $ ./manage.py fobi_sync_plugins
        
        If your HTTP server is running, you would then be able to see the new plugin
        in the edit form interface.
        
        Creating a form callback
        ===============================================
        Form callbacks are additional hooks, that are executed on various stages of
        the form submission.
        
        Let's place the callback in the `foo` module. The plugin directory should then
        have the following
        structure.
        
        .. code-block:: none
        
            path/to/foo/
            ├── __init__.py
            └── fobi_form_callbacks.py # Where callbacks are defined and registered
        
        See the callback example below.
        
        Required imports.
        
        .. code-block:: python
        
            from fobi.constants import (
                CALLBACK_BEFORE_FORM_VALIDATION,
                CALLBACK_FORM_VALID_BEFORE_SUBMIT_PLUGIN_FORM_DATA,
                CALLBACK_FORM_VALID, CALLBACK_FORM_VALID_AFTER_FORM_HANDLERS,
                CALLBACK_FORM_INVALID
                )
            from fobi.base import FormCallback, form_callback_registry
        
        Define and register the callback
        
        .. code-block:: python
        
            class SampleFooCallback(FormCallback):
                stage = CALLBACK_FORM_VALID
        
                def callback(self, form_entry, request, form):
                    print("Great! Your form is valid!")
        
            form_callback_registry.register(SampleFooCallback)
        
        Add the callback module to ``INSTALLED_APPS``.
        
        .. code-block:: python
        
            INSTALLED_APPS = (
                # ...
                'path.to.foo',
                # ...
            )
        
        Suggestions
        ===============================================
        Custom action for the form
        -----------------------------------------------
        Sometimes, you would want to specify a different action for the form.
        Although it's possible to define a custom form action (``action`` field
        in the "Form properties" tab), you're advised to use the ``http_repost`` 
        plugin instead, since then the form would be still validated locally
        and only then the valid data, as is, would be sent to the desired
        endpoint.
        
        Take in mind, that if both cases, if CSRF protection is enabled on
        the endpoint, your post request would result an error.
        
        When you want to customise too many things
        -----------------------------------------------
        Fobi, with its' flexible form elements, form handlers and form callbacks
        is very customisable. However, there might be cases when you need to
        override entire view to fit your needs. Take a look at the
        `FeinCMS integration
        <https://github.com/barseghyanartur/django-fobi/tree/stable/src/fobi/contrib/apps/feincms_integration/widgets.py>`_
        or `DjangoCMS integration
        <https://github.com/barseghyanartur/django-fobi/blob/stable/src/fobi/contrib/apps/djangocms_integration/cms_plugins.py>`_
        as a good example of such. You may also want to compare the code from original
        view ``fobi.views.view_form_entry`` with the code from the widget to get a
        better idea of what could be changed in your case. If need a good advice,
        just ask me.
        
        Theming
        ===============================================
        `Fobi` comes with theming API. While there are several ready-to-use themes:
        
        - Bootstrap 3 theme
        - Foundation 5 theme
        - Simple theme in style of the Django admin
        
        Have in mind, that creating a brand new theme could be time consuming.
        Instead, you are advised to extend existing themes or in the worst case,
        if too much customisation required, create your own themes based on
        existing ones (just copy the desired theme to your project directory and
        work it out further).
        
        It's possible to use different templates for all "view" and "edit"
        actions (see the source code of the "simple" theme). Both Bootstrap 3 and
        Foundation 5 themes look great. Although if you can't use any of those,
        the "simple" theme is the best start, since it looks just like django-admin.
        
        Create a new theme
        -----------------------------------------------
        
        Let's place the theme in the `sample_theme` module. The theme directory 
        should then have the following structure.
        
        .. code-block:: none
        
            path/to/sample_theme/

        Registering the ``SampleTheme`` plugin.
        
        .. code-block:: python
        
            theme_registry.register(SampleTheme)
        
        Sometimes you would want to attach additional properties to the theme
        in order to use them later in templates (rememeber, current theme object
        is always available in templates under name `fobi_theme`).
        
        For such cases you would need to define a variable in your project's settings
        module, called ``FOBI_CUSTOM_THEME_DATA``. See the following code as example:
        
        .. code-block:: python
        
            # Fobi custom theme data for to be displayed in third party apps
            # like `django-registraton`.
            FOBI_CUSTOM_THEME_DATA = {
                'bootstrap3': {
                    'page_header_html_class': '',
                    'form_html_class': 'form-horizontal',
                    'form_button_outer_wrapper_html_class': 'control-group',
                    'form_button_wrapper_html_class': 'controls',
                    'form_button_html_class': 'btn',
                    'form_primary_button_html_class': 'btn-primary pull-right',
                },
                'foundation5': {
                    'page_header_html_class': '',
                    'form_html_class': 'form-horizontal',
                    'form_button_outer_wrapper_html_class': 'control-group',
                    'form_button_wrapper_html_class': 'controls',
                    'form_button_html_class': 'radius button',
                    'form_primary_button_html_class': 'btn-primary',
                },
                'simple': {
                    'page_header_html_class': '',
                    'form_html_class': 'form-horizontal',
                    'form_button_outer_wrapper_html_class': 'control-group',
                    'form_button_wrapper_html_class': 'submit-row',
                    'form_button_html_class': 'btn',
                    'form_primary_button_html_class': 'btn-primary',
                }
            }
        
        You would now be able to access the defined extra properties in templates
        as shown below.
        
        .. code-block:: html
        
            <div class="{{ fobi_theme.custom_data.form_button_wrapper_html_class }}">
        
        You likely would want to either remove the footer text or change it. Define
        a variable in your project's settings module, called ``FOBI_THEME_FOOTER_TEXT``.
        See the following code as example:
        
        .. code-block:: python
        
            FOBI_THEME_FOOTER_TEXT = gettext('&copy; django-fobi example site 2014')
        
        Below follow the properties of the theme:
        
        - ``base_edit``
        - ``base_view``
        
        There are generic templates made in order to simplify theming. Some
        of them you would never need to override. Some others, you would likely
        want to.
        
        Templates that you likely would want to re-write in your custom
        theme implemention are marked with three asterics (\*\*\*):
        
        .. code-block:: none

        the most influenced by the Bootstrap 3 theme.
        
        Make changes to an existing theme
        -----------------------------------------------
        As said above, making your own theme from scratch could be costy. Instead,
        you can override/reuse an existing one and change it to your needs with
        minimal efforts. See the `override simple theme
        <https://github.com/barseghyanartur/django-fobi/tree/master/examples/simple/override_simple_theme/>`_
        example. In order to see it in action, run the project with
        `settings_override_simple_theme
        <https://github.com/barseghyanartur/django-fobi/blob/master/examples/simple/settings_override_simple_theme.py>`_

        Permissions
        ===============================================
        Plugin system allows administrators to specify the access rights to every
        plugin. Fobi permissions are based on Django Users and User Groups. Access
        rights are managable via Django admin ("/admin/fobi/formelement/",
        "/admin/fobi/formhandler/"). If user doesn't have the rights to access plugin,
        it doesn't appear on his form even if has been added to it (imagine, you have
        once granted the right to use the news plugin to all users, but later on
        decided to limit it to Staff members group only). Note, that superusers have
        access to all plugins.

        Management commands
        ===============================================
        There are several management commands available.
        
        - `fobi_find_broken_entries`. Find broken form element/handler entries that
          occur when some plugin which did exist in the system, no longer exists.
        - `fobi_sync_plugins`. Should be ran each time a new plugin is being added to
          the Fobi.
        - `fobi_update_plugin_data`. A mechanism to update existing plugin data in 
          case if it had become invalid after a change in a plugin. In order for it
          to work, each plugin should implement and ``update`` method, in which the
          data update happens.
        
        Tuning
        ===============================================
        There are number of Dash settings you can override in the settings module of
        your Django project:
        
        - `FOBI_RESTRICT_PLUGIN_ACCESS` (bool): If set to True, (Django) permission 
          system for dash plugins is enabled. Defaults to True. Setting this to False
          makes all plugins available for all users.
        - `FOBI_DEFAULT_THEME` (str): Active (default) theme UID. Defaults to
          "bootstrap3".
        - `FORM_HANDLER_PLUGINS_EXECUTION_ORDER` (list of tuples): Order in which the
          form handlers are executed. See the "Prioritise the excecution order"
          section for details.
        
        For tuning of specific contrib plugin, see the docs in the plugin directory.
        
        Bundled plugins and themes
        ===============================================
        Fobi ships with number of bundled form element- and form handler- plugins, 
        as well as themes which are ready to be used as is.
        
        Bundled form element plugins
        -----------------------------------------------
        Below a short overview of the form element plugins. See the README.rst file
        in directory of each plugin for details.

        HTML5 fields
        ===============================================
        The following HTML5 fields are supported in appropriate bundled plugins:
        
        - date
        - datetime
        - email
        - max
        - min
        - number
        - url
        - placeholder
        - type
        
        With the `fobi.contrib.plugins.form_elements.fields.input` support for
        HTML5 fields is extended to the following fields:
        
        - autocomplete
        - autofocus
        - list
        - multiple
        - pattern
        - step
        
        Available translations
        ===============================================
        - Dutch (core and plugins)
        - Russian (core and plugins)
        
        Debugging
        ===============================================
        By default debugging is turned off. It means that broken form entries, which
        are entries with broken data, that are not possible to be shown, are just
        skipped. That's safe in production. Although, you for sure would want to
        see the broken entries in development. Set the ``FOBI_DEBUG`` to True
        in the ``settings.py`` of your project in order to do so.
        
        Most of the errors are logged (DEBUG). If you have written a plugin and it
        somehow doesn't appear in the list of available plugins, do run the following
        management command since it not only syncs your plugins into the database,
        but also is a great way of checking for possible errors.
        
        .. code-block:: none
        
            ./manage.py fobi_sync_plugins
        
        Run the following command in order to identify the broken plugins.
        
        .. code-block:: none
        
            ./manage.py fobi_find_broken_entries
        
        If you have forms refering to form element- of form handler- plugins
        that are currently missing (not registered, removed, failed to load - thus
        there would be a risk that your form would't be rendered properly/fully and
        the necessary data handling wouldn't happen either) you will get an
        appropriate exception. Although it's fine to get an instant error message about 
        such failures in development, in production is wouldn't look appropriate.
        Thus, there are two settings related to the non-existing (not-found) form
        element- and form handler- plugins.
        
        - FOBI_DEBUG: Set this to True in your development environment anyway. Watch
          error logs closely.
        - FOBI_FAIL_ON_MISSING_FORM_ELEMENT_PLUGINS: If you want no error to be
          shown in case of missing form element plugins, set this to False in
          your settings module. Default value is True.
        - FOBI_FAIL_ON_MISSING_FORM_HANDLER_PLUGINS: If you want no error to be
          shown in case of missing form element handlers, set this to False in
          your settings module. Default value is True.
        
        Troubleshooting
        ===============================================
        If you get a ``FormElementPluginDoesNotExist`` or a
        ``FormHandlerPluginDoesNotExist`` exception, make sure you have listed your
        plugin in the `settings` module of your project.
