Class-based view delegate to another view

Question

Is it possible to have a class based view delegate to a particular class-based view? Specifically what I'd like to do is have / point to a view called 'home' and the home view with delegate to View A if the user is logged in, or View B if no user is logged in. Alternatively I could do a redirect to a different URL. I'm not sure what would be the best practice here.

Answer 1

You can call another view from within a view in the same manner used in urls

class HomeView( TemplateView ):
  template_name="index.html"

  def dispatch( self, request, *args, **kwargs ):
    if request.user.is_authenticated():
      view=UserHomeView.as_view()
      return view( request, *args, **kwargs )
    return super( HomeView, self ).dispatch( request, *args, **kwargs )


class UserHomeView( TemplateView ):
  template_name="user.html"

Answer 2

You can just redirect to a different url and that url is also served by a class based view.

urls.py

url(r'^$', HomeView.as_view(), name='home'),
url(r'^login/', LoginView.as_view(), name='login'),
url(r'^welcome/$', WelcomeView.as_view(), name='welcome')

views.py

class HomeView(TemplateView):

    def get(self, request, *args, **kwargs):
        if request.user.is_authenticated():
            return HttpResponseRedirect(reverse('welcome'))
        else:
            return HttpResponseRedirect(reverse('login'))

class WelcomeView(TemplateView):

    def get(self, request, *args, **kwargs):
        #do something

class LoginView(TemplateView):

    def get(self, request, *args, **kwargs):
        #show login page
