Django Mixins vs Abstract Classes

What are the main differences between Django mixins and abstract classes?

Django mixins are reusable classes that provide specific functionality to other classes, while abstract classes serve as blueprints for other classes and cannot be instantiated directly.

Can you give me an example of when to use a mixin?

Sure! If you have multiple views that need to handle user permissions, you can create a PermissionMixin to encapsulate that logic and reuse it across those views.

What about abstract classes? When should I use them?

Abstract classes are useful when you want to define a common interface for a group of related classes. For instance, if you have different types of user profiles, you can create an abstract UserProfile class with shared methods.

Are there any performance considerations when using mixins?

Yes, using too many mixins can lead to complexity and potential performance issues due to the method resolution order (MRO). It's best to use them judiciously.
