从Tastypie URL检索变量和处理列表

Question

Let's say my override_urls is like so:

def override_urls(self):
    return [
        url(r"^(?P<resource_name>%s)/(?P<user__username>\w{4,30})%s$" % (self._meta.resource_name, trailing_slash()), self.wrap_view('dispatch_list'), name="api_dispatch_list"),
        ]

I'd like to do some custom processing owith user__username: I'd like to get all of a user's 'post' objects and combine it with everyone they follow's post objects.

How can I nab user__username for get_object_list to process? I tried to get it from the request using request.GET.get('user__username') but that didn't seem to make sense (and didn't work).

PS, is there anyway to make user__username into just username (for the sake of prettyness)?

Answer 1

The user_username argument is passed in kwargs through the dispatching process not in request.GET.

You probably would want to override the get_list method and process the additional argument inside it. If you do it that way you can name your argument whatever you want and process it the way you wish.
