I tried that:
favorites = Photo.objects.filter(likes__user=user).order_by("-likes__id")
and it seems to work well in all the tests. The only thing I don't
understand is how it works. Because in this generic relation there are
various 'likes' for each 'Photo' object and so the
'filter(likes__user=user)' part must iterate through them in a way. Anyway
it works.
Cheers,
Bastian
