A Mixin is a special kind of inheritance in Python (and other object-oriented languages) and it’s starting to get a big rise in Django / Web Application Development. You can use a Mixin to allow classes in Python to share methods between any class that inherits from that Mixin.
Up Next. This method can be used in templates, and also in the Django admin site, to preview the saved object.
