Abstract CBV mixin that gives access Ideally, a mixin should carry all the state it is going to access, and the logic to handle it. E.g. a good mixin could add a last_updated field to an ORM model class, In object-oriented programming languages, a mixin is a class which contains a combination of methods from other classes. Add timestamp and trashed attribute I've been huge fan of Django's class-based views (CBVs) since I first tried them out in Django 1.4.

Here's a simple example to illustrate what I've been doing. In building Work for Pie, we've got a UserProfile model that looks something like this: The border-mixin would add a border around an object and has a method computing its width. A new class bordered-button (that is both a graphical object and uses the border mixin) would compute its width by calling all applicable width methods—via the + method combination.

I've been using Mixins lately to DRY-ly make certain behavior available to several different Django models. If you're not familiar with mixins, there's a great discussion over on StackOverflow. Here's a simple example to illustrate what I've been doing. In building Work for Pie, we've got a UserProfile model that looks something like this:
