Member | Convert Member to a subclass of User

[giobber]

One of the ways to extend a model in django is via inheritance, essentially when i subclass a model in django it create a hidden OneToOneField relation (unique=True, primary=True, null=False) by using Base class index as index for children.

For more info see Django Documentation

Pro

• Member is always connected to a single User
• Teacher and Member now could be coexists without problem
• I could still create a User without Member or Teacher
• first_name, last_name and email now are set and accessed between User, Member and Teacher without useless complications

Contro

• I cannot create Member without User (but we already decided it complicates relations)
• I cannot delete user without deleting associated Members/Teachers (see above)
• At the moment is required to extend User model by calling it directly which is not best practice

Sample code

from ..core.models import User

class Member(User):
  ...

After discussion and some other tests, Member as User subclass is not the best way to manage situation In Admin User could be created inside Member page, Teacher should be free to be without a User The only lost feature is the possibility to see first_name, last_name and email as Member fields in admin table page but this is not a great loss

NOTE: first_name and last_name are removed from Member and make required as email field
