Http verb decorator for Django?

In ASP.NET MVC, you can use the AcceptVerbs attribute to correlate the view function with the verb:

public ActionResult Create()
{
    // do get stuff
} 

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Create(FormCollection collection)
{
    // do post stuff
}

Django's book suggests something like this:

def method_splitter(request, *args, **kwargs):
    get_view = kwargs.pop('GET', None)
    post_view = kwargs.pop('POST', None)
    if request.method == 'GET' and get_view is not None:
        return get_view(request, *args, **kwargs)
    elif request.method == 'POST' and post_view is not None:
        return post_view(request, *args, **kwargs)
    raise Http404

urls.py:

urlpatterns = patterns('',
    # ...
    (r'^somepage/$', views.method_splitter, {'GET': views.some_page_get, 
        'POST': views.some_page_post}),
    # ...
)

It seems a little ugly to me - is there a decorator that can associate an HTTP verb with a view, ASP.NET MVC style, or some other acceptable way to do this?

There are standard built-in decorators for requesting a specific HTTP method or a list of allowed methods.

See code: http://code.djangoproject.com/browser/django/trunk/django/views/decorators/http.py .

You can use View Decorators

From the docs:

from django.views.decorators.http import require_http_methods

@require_http_methods(["GET", "POST"])
def my_view(request):
    # I can assume now that only GET or POST requests make it this far
    # ...
    pass
