Allows using controllers for views.
This allows for nice subclassing to override behavior of views. Controller.urls (see below) works fine for subclasses as well.
Similar to snippet #1165 except that it won't break reverse URL resolving and regex validation in URLs.
In views.py:
import mvc
class MyController(mvc.Controller):
@mvc.view('myview/$', 'myview')
def my_view(self):
# do something with self.request
return HttpResponse('something')
class Meta(mvc.Controller.Meta):
url_prefix = 'mycontroller-'
In urls.py:
from . import views
urlpatterns = patterns('',
# ... other urls here ...
*views.MyController.urls(r'prefix/')
)
Then the view MyController.my_view will be accessible from 'prefix/myview/' and have the name 'mycontroller-myview', i.e. reverse('mycontroller-myview') will work as expected.

Helpers for coding in a more MVC-fashion using Controller classes as opposed
to views.
