What is model inheritance in Django ORM?

Model inheritance in Django ORM allows you to create a base model and then extend it with child models, promoting code reuse.

Can you give me an example of how to implement it?

Sure! You can create a base model with common fields, then create child models that inherit from it. For instance:

class Animal(models.Model):
    name = models.CharField(max_length=100)

class Dog(Animal):
    breed = models.CharField(max_length=100)

class Cat(Animal):
    color = models.CharField(max_length=100)

What are the types of model inheritance in Django?

Django supports three types of model inheritance: abstract base classes, multi-table inheritance, and proxy models.

When should I use each type of inheritance?

Use abstract base classes for shared fields without creating a database table, multi-table for separate tables with relationships, and proxy models for changing behavior without altering the database schema.
