context = super(UBaseTemplateView, self).get_context_data(**kwargs)

To do this you apply the decorator to the dispatch() method of the class. The decorators will process a request in the order they are passed to the decorator. In the example, never_cache() will process the request before login_required() . In this example, every instance of ProtectedView will have login protection.
Django views are Python functions that takes http requests and returns http response, like HTML documents. A web page that uses Django is full of views with different tasks and missions.
We have mentioned that class-based views don't replace function-based views. In some cases, function-based views are better and in some cases, class-based views are better. In the implementation of the list view, you can get it working by subclassing the ListView and overriding the attributes.
You cannot set_cookie on a request, only on response, but burhan-khalid was going in the correct direction. get_context_data only returns a dictionary, so you cannot access the response there. You have to access it either in dispatch, or with a TemplateView, in render_to_response. Here is an example:
class MyView(TemplateView):
def render_to_response(self, context, **response_kwargs):
response = super(MyView, self).render_to_response(context, **response_kwargs)
response.set_cookie("success","success")
return response
I would suggest you shouldn't do all your processing code in get_context_data. You may need to refactor to get the cookie you want set in render_to_response.
