How do I use models and mixins in Django?

In Django, models are used to define the structure of your database. Mixins are reusable classes that can add functionality to your models.

Can you give me an example of a model with a mixin?

Sure! Here's a simple example:

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

class Post(TimestampMixin, models.Model):
    title = models.CharField(max_length=100)
    content = models.TextField()

What are the benefits of using mixins?

Mixins promote code reusability and help keep your models DRY (Don't Repeat Yourself) by allowing you to share common functionality across different models.

Are there any built-in mixins in Django?

Yes, Django provides several built-in mixins, such as MultipleObjectMixin and FormMixin, which can be very useful in class-based views.
