What are abstract models in Django ORM?

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

How do I create an abstract model?

To create an abstract model, you define a class that inherits from models.Model and set Meta with abstract = True.

Can you give me an example of an abstract model?

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 models?

The benefits include code reusability, cleaner models, and easier maintenance since common fields are defined in one place.
