You shouldn't override dispatch, but the class method as_view()

See the docs, which have just been written and also the just-closed issue where we discussed it.

The reason you shouldn't override dispatch is because things break if dispatch doesn't always accept a compatible set of params

I followed the link, and read the documentation, but they instruct and show one to decorate the dispatch method:
https://docs.djangoproject.com/en/2.2/topics/class-based-views/intro/#decorating-the-class
Are you sure about .as_view()?
