Add fields and extend Django's built-in Group
model using a OneToOneField
(i.e. a profile model). In this example, we add a UUIDField
. Whenever a new group is created, we automatically (via signals) create a corresponding Role
record referencing the newly created group. Whenever a Group is deleted, the corresponding Role is deleted as well.
