Restrict the period of access. start_datetime specifies the date and time when access will be available, and end_datetime with the last date and time when access is available. You can change the date and time that can be accessed dynamically by overriding the get_start_datetime and get_end_datetime methods, respectively.

Let your Mixin derive from object and add all fields dynamically in the Mixin's init method.

A default context mixin that passes the keyword arguments received by from django.views.generic.base import ContextMixin. A mixin class that performs template-based response rendering for views that operate upon a list of object instances.

In object-oriented programming languages, a mixin (or mix-in) is a class that contains methods for use by other classes without having to be the parent class of those other classes. How those other classes gain access to the mixin's

However there is an easy and pythonic/djangoic way to accomplish that: just use a Mixin.

Furthermore the fields some model methods will be needed at more than one models. Thus these methods could be added to mixins to prevent code repetition. Writing mixins for Django Class Based Views. Mixins are a natural fit for class based views just like decorators are a natural fit for function based views. To write mixins for a class based view, it is often good to know a little about the view lifecycle. Lets go through some lifecycle methods in order: In Python, this rule goes by the name of MRO (Method Resolution Order), which was introduced in Python 2.3 and is described in this document by Michele Simionato. There is a lot to say about MRO and the underlying C3 linearisation algorithm, but for the scope of this post, it is enough to see how it solves the diamond problem.
