You are trying to access photo_set on the model class, rather than an
instance of the class. You must create an instance of the class, and
then use that.

>>> s.tvepisode_set.all()
[<TVEpisode: 1x01 - Pilot>, <TVEpisode: 1x02 - Last Baby Proofing
Standing>, <TVEpisode: 1x03 - TBA>]
>>> TVSeries.tvepisode_set.all()
Traceback (most recent call last):
File "<console>", line 1, in <module>
AttributeError: 'ForeignRelatedObjectsDescriptor' object has no attribute 'all'
