What are Django Abstract Base Classes?

What are Django Abstract Base Classes?

Django Abstract Base Classes are a way to create a base class that other models can inherit from, allowing for shared fields and methods.

Can you give me an example of how to use them?

Sure! You can define an abstract base class like this:

from django.db import models

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

    class Meta:
        abstract = True

Then, other models can inherit from CommonInfo.

What are the benefits of using abstract base classes?

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

Are there any limitations I should be aware of?

Yes, since they are abstract, you cannot create instances of the abstract class itself, only of the subclasses.
