What is model Inheritance?
Model Inheritance in Django works almost identically to the way normal class inheritance works in python. In this article we will revolve around how to create abstract base class in Django Models.
Abstract Base Class :-
Abstract Base Class are useful when you want to put some common information into a number of other models. You write your base class and put abstract = True in the Meta Class. Suppose you have two model Student and Teacher.
So have you notice that one field name is common on both models.
So instead of adding common fields in both models ,we have create a another model and put those common fields in that model.
So here I create a model common and put the common fields in that model.
Put abstract = True in the Meta class. After set abstract True, now it becomes an abstract class not a model,so now you can’t generate a database table.
python3 manage.py makemigrations
python3 manage.py migrate
Now you can inherit the common name field in both Student and Teacher. Just like normal python inheritance.
