Calls a view by request.method value.
To use this dispatcher write your urls.py like this:
urlpatterns = pattern('',
url(r'^foo/$', dispatch(head=callable1,
get=callable2,
delete=callable3)),
)
If request.method
is equal to head, callable1
will be called as your usual view function;
if it is get
, callable2
will be called; et cetera.
If the method specified in request.method is not one handled by dispatch(..)
,
HttpResponseNotAllowed
is returned.

I really like this. It always bothered me (with RESTful stuff, anyway) how the one handler does GET and PUT, etc.
