Django Unleashed

18.6 Switching to GCBVs with PostGetMixin in Post Views

Instead of removing behavior from DateDetailView, we should be adding behavior to DetailView.

In Chapter 17, we saw that DetailView uses the get_object() method to actually fetch the object from the database. We can therefore create a mixin class to override the method and use multiple inheritance to override this in DetailView and other GCBVs, as shown in Example 18.31.
