It’s more than ok to guive the user reference only to the Album. That is
what is called normalization in the relational world.
About your first question, my solution is extract this logic from the model
itself. I think it’s better to create a service object to do that.
Eg:
class PhotoManager(object):
def __init__(user):
self._user = user
def add_photo(photo, album=None):
if album is None:
album = self._user.get_default_album()
album.add_photo(photo)
