How to implement multiple relationships between models in Django?

Question

Django

Tell me how to implement a connection between one model and several others.
I have

Carrier
  carrier_id
  name 

Partner
  partner_id
  carrier_id
  name

Company
  company_id
  partner_id
  name

Administrator
  entity_type (Сarrier, Partner, Company)
  email

Such things are not done by the standard type of communication, as I understand it?

Answer 1

Either through inheritance of models from a common root, or through generalized relations .
