Questions tagged [django-class-based-views]

Django Class-based Views are Django views that are represented as classes. These allow you to structure your views and reuse code by harnessing inheritance and mixins.

Class-based views provide an alternative way to implement views as Python objects instead of functions. They do not replace function-based views, but have certain differences and advantages when compared to function-based views:

  • Organization of code related to specific HTTP methods (GET, POST, etc) can be addressed by separate methods instead of conditional branching.
  • Object oriented techniques such as mixins (multiple inheritance) can be used to factor code into reusable components.
