Policy vs FieldPolicy
I haven't used FieldPolicy before, but lets say I have a :role attribute that I want to control changes to. I.e: :god should be able to create users with all roles, :admin should only be able to create :admin and :user, and :user should not be able to create any roles - but still able to edit their own account i.e: change their email etc. Would a field policy be the place for that these days?
