I think the problem is that you are using queries which are in the form: (id = some_list_of_items) and you cannot do that. Have a look at the "_in" syntax: https://docs.djangoproject.com/en/dev/ref/models/querysets/#in
(That whole document is very useful one to read and understand; as making queries is at the heart of interacting with your data.)
