What is multi-table inheritance in Django models?

Multi-table inheritance in Django allows you to create a base model and extend it with child models, each having their own database table.

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

Sure! You can define a base model and 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)

How does Django handle the database tables for these models?

Django creates a separate table for each model. The child tables will have a foreign key to the parent table, allowing for efficient data retrieval.

What are the advantages of using multi-table inheritance?

It promotes code reusability and allows for a clear hierarchical structure, making it easier to manage related data.
