- Allow you to structure your views and reuse code by harnessing inheritance and mixins.
- Provide an alternative way to implement views as Python objects instead of functions.
- Do not replace function-based views, but have certain differences and advantages when compared to function-based views.
- If you have tried function based generic views in the past and found them lacking, you should not think of class-based generic views as a class-based equivalent, but rather as a fresh approach to solving the original problems that generic views were meant to solve.
