string as second argument in url dispatcher for CBV

Before class based views my urls.py looked like that:

urlpatterns= patterns('mypackage.views',
                      url(r'^$', 'home', name='home'),
                      url(r'other', name='other'),
                      )

Now my home view is class based. As i like uniformity, I do not would like to keep the view class as string. I tried:

urlpatterns= patterns('mypackage.views',
                      url(r'^$', 'Home.as_view', name='home'),
                      url(r'Other.as_view', name='other'),
                      )

and I get Parent module mypackage.views.Home does not exist . If I simply give the class name like:

urlpatterns= patterns('mypackage.views',
                      url(r'^$', 'Home', name='home'),
                      url(r'Other', name='other'),
                      )

I get: __init__ takes exactly 1 argument, 2 given

Is there a way to pass a string as second argument to the url function for CBV as for FBV instead of from mypackage.views import * ?

EDIT: There seems to be no built-in solution for this. In this case: why are strings as second parameter allowed for the url function: Doesn't it violate the zen ("there is only one way to do this)?

If you want to pass your view as string, then in your views do this:

class Home(View):
    pass

home = Home.as_view()

then in your url:

url(r'^$', 'mypackage.views.home', name='home'),

You need to use full path.

You should import the class-based view and specify them that way:

from mypackage.views import *

urlpatterns = patterns('mypackage.views',
                       url(r'^$', Home.as_view(), name='home'),
                       url(r'other', Other.as_view() name='other'),
                       )

Also note that your url() calls should have three parameters: the URL pattern, the view and name (some examples you wrote don't have all of these).
