What is Django ORM inheritance and how does it work?

Django ORM inheritance allows you to create a hierarchy of models. There are three types: abstract base classes, multi-table inheritance, and proxy models.

Can you explain the difference between these types?

Sure! Abstract base classes don't create a database table, multi-table inheritance creates a separate table for each model, and proxy models allow you to change the behavior of a model without changing its fields.

When should I use each type of inheritance?

Use abstract base classes when you want to share common fields without creating a table. Multi-table inheritance is useful when you need to extend a model with additional fields, and proxy models are great for altering behavior without modifying the database schema.

Can you give me a code example for multi-table inheritance?

Certainly! Here's a simple example:

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

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