What are abstract base classes in Django ORM?

Abstract base classes in Django ORM allow you to define common fields and methods that can be inherited by other models.

How do I create an abstract base class in Django?

You can create 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 CommonInfo(models.Model):
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)

    class Meta:
        abstract = True

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

What are the benefits of using abstract base classes?

They promote code reuse and help maintain a clean and organized codebase by centralizing common functionality.
