What are Django abstract models and how do I use them?

Django abstract models are base classes that don't create a database table. They allow you to define common fields and methods for other models.

Can you give me an example of how to create an abstract model?

Sure! You can create an abstract model by setting abstract = True in the Meta class. Here's a simple example:

from django.db import models

class BaseModel(models.Model):
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)

    class Meta:
        abstract = True

class Product(BaseModel):
    name = models.CharField(max_length=100)
    price = models.DecimalField(max_digits=10, decimal_places=2)

What are the benefits of using abstract models?

Abstract models promote code reusability and help maintain a clean codebase by allowing you to define common fields and methods in one place.

Can I inherit from multiple abstract models?

No, Django does not support multiple inheritance for models. You can only inherit from one abstract model at a time.
