You will need to provide more information, such as the actual
traceback. I don't believe that the 'print item.photo_set' line can be
working if in the very next line you're getting an error which in
effect says that item.photo_set is None.
As an aside, I must say that you are very likely to get extremely
confused with your models and fields named the way they are. 'xxx_set'
is usually used in Django for the automatically-created reverse
relation on ForeignKeys - so in this case, the reverse relation from
PhotoSet to Event would be called event_set - and this is always a
queryset. Calling your actual FK 'photo_set' is bound to lead to
confusion.
