to make stroller work inside your application you must add:

INSIDE MODEL.PY
       from stroller.model import init_stroller_model
       Product, ProductInfo, Category, Order, OrderItem =
init_stroller_model(DBSession, DeclarativeBase)

INSIDE HELPERS.PY
       from stroller.helpers import stroller_url, icons, category_icon

INSIDE WEBSETUP.PY
           from stroller.model import setup_stroller_database
           from stroller.model import init_stroller_model

           init_stroller_model(DBSession, DeclarativeBase, User, Group)
           setup_stroller_database(DBSession, DeclarativeBase, User, Group)

INSIDE ROOT.PY
       from stroller.controllers.ecommerce import StrollerController
**inside the rootcontroller**
       shop = StrollerController()

it should then be possible to access stroller from the /shop url of the
application
