As Malcolm said, within get_absolute_url, self is already the Photo
instance, so it is confusing what you are trying to get at when you use
'self.photo' here. In fact given the models you have defined, self.photo is
referencing the model manager for the set of Gallery instances that have
self as 'featured_photo'. (I think you might want to rethink that
related_name specification, since it seems to be confusing enough to have
tripped you up here.)
Within get_absolute_url, to refer to the photo instance, just use self, not
self.photo. When you fix that you are going to hit an error because the
Place model does not have a slug field, and yet you are trying to access it
when you code self.place.slug. I don't know what you are really intending
to specify here.
