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.

In the example, sometimes the "Cannot make decisions based on self.access_a nor self.access_long" exists in yet another mixin, as the pattern is repeated across a large number of views. We find the duplication increases the maintenance burden as when writing a new new views, the developer must remember to include these repetitive calls. However, in Python the class hierarchy is defined right to left, so in this case the Mixin2 class is the base class, extended by Mixin1 and finally by BaseClass.This is usually fine because many times the mixin classes don't override each other's, or the base class' methods. The method handlers for a ViewSet are only bound to the corresponding actions at the point of finalizing the view, using the .as_view() method. Typically, rather than explicitly registering the views in a viewset in the urlconf, you'll register the viewset with a router class, that automatically determines the urlconf for you. views.py: Here is views.py in which we can create our method like GET, PUT, POST, DELETE.I have created GET and POST using class-based views of Django. In GET method we are returning data from the model by calling React.objects.all() and then using list comprehension to convert the author and their quotes in python’s dictionary.
