What are abstract base classes in Django models?

Abstract base classes in Django are a way to create a base model that other models can inherit from without creating a separate database table for the base class.

How do I define an abstract base class in Django?

You can define an abstract base class by setting the Meta class attribute abstract = True in your model.

Can you give me an example of an abstract base class?

Sure! Here's a simple example:

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 base classes?

The benefits include code reusability, cleaner models, and the ability to define common fields and methods in one place.
