API: patch/N/checks/ shows all checks, not just checks for the patch

[mpe]

In the API you can go to a patch's detail page:

http://patchwork.ozlabs.org/api/1.0/patches/949686/

And that has a link to the checks for the patch:

http://patchwork.ozlabs.org/api/patches/949686/checks/

But the latter shows all checks ever, not just the checks for the patch.

This makes it impossible to automatically look at the checks for a given patch ID using the API.

I tried to find where the bug is but I don't know django REST framework well enough.

The URL match is:

        url(r'^patches/(?P<patch_id>[^/]+)/checks/$',
            api_check_views.CheckListCreate.as_view(),
            name='api-check-list'),

And CheckListCreate does lookup the patch and stash it in request:

        p = Patch.objects.get(id=patch_id)
        if not p.is_editable(request.user):
            raise PermissionDenied()
        request.patch = p

But from there I don't know what's supposed to use request.patch, maybe CheckFilterSet ?
