for p in products.objects.all():
for c in p.categories.all():

If I am not mistaken, editable=False is only applicable to the admin-

superuser and then give them a form to add an email address.

I am not sure I understand, I think you want to archive a model
instance? or put another way, when the model is no longer active or
useful to the user, you would essentially like to treat that database
record differently than other records. In that case, you could simply

I am not sure why you would want "all companies bank accounts in

appropriate people are able to view the records of any given company?

I have an app that uses a roll-my-own role-based access system to
restrict access to various model instances. Essentially what happens
is that there is a role or roles assigned to users that allow them to
either view or edit various asset types based on the owning
organization. Many of the asset
