Class-based URLs configuration

Django url routing configuration composed from lists of mapping between url path expressions and views functions. URL configuration could be more then just a list. viewflow.fsm.Viewset is the class that can be used as part of url configuration. These allow you to structure your code and quickly connect and customize predefined sets of URLs.

Viewflow provides viewset for organizing CRUD, Workflow logic, perform authentication and connect other 3d part packages. The default behavior could be customized by inheriting and overriding base classes attributes and methods.

from django.urls import path
from viewflow.urls import Viewset

class WebsiteViewset(Viewset):
    index_path = path('', index_view, name='index')

Basically, a Viewset is the class with .urls property, suitable to include into Django root URL config in your main

viewset = WebsiteViewset()

urlpatterns = [
    path('', viewset.urls)

viewset.urls list contains all paths from the class attributes with _path suffix

To mix url definition with other class method, an url attribute could be a property

def page_path(self):
    return path('page/', self.page_view, name='page'))

def page_view(self, request);
    return render(request, 'page.html')

A Viewset could contain other viewset

from viewflow.urls import route, Viewset

class UserViewset(Viewset):
    page_path = path('account/', self.account_view name="account")

class WebsiteViewset(Viewset):
    users_path = route('auth/', UserViewset())

All Viewset URLs are prefixed with namespace. Each part of Django URL configuration could have application and instance namespace

By default, Viewset application namespace are determined from viewset class name, by lowering in and stripping common suffixes like Viewset. In the sample above, WebsiteViewset has ‘website:’ namespace, and nested UserViewset has ‘website:user:’

from django.urls import reverse

>>> reverse('website:index')

>>> reverse('website:page')

>>> reverse('website:user:account')

To manually specify a viewset namespace, use app_name class attribute or pass the app_name keyword parameter to the viewset constructor.

class UserViewset(Viewset):
    page_path = path('account/', self.account_view name="account")

class WebsiteViewset(Viewset):
    app_name = 'main'

    users_path = route('auth/', UserViewset(app_name='profile'))

>>> reverse('main:profile:account')
