Adding extra_context in Django logout built-in view

Question

In django/contrib/auth/views.py there is the definition of the logout view :

def logout(request, next_page=None,
       template_name=\'registration/logged_o

I had a similar problem with titles and generic views in django 1.11 (though the problem was mostly that I didn't switch docs version from 2.0). I wanted to pass title via extra_context to the view inherited from CreateView, and discovered that django's generic view had no such attribute. So, here are my crutches:

1. Create custom mixin (hope that's more or less what ContextMixin in 2.0 does):

   class ExtraContextMixin():
       extra_context = {}
   
       def get_context_data(self, **kwargs):
           context = super().get_context_data(**kwargs)
           context.update(self.extra_context)
   
           return context
   

2. Add mixin to view's ancestors (that's all code I had to change):

   class CustomView(ExtraContextMixin, CreateView):
   

3. Pass extra_context from url:

   url(r'^custom-view/$', views.CustomView.as_view(extra_context={'title': 'just any'}), name='custom-view')
   

Unfortunately, I have no idea whether such solution is acceptable (no need since 2.0, obviously), but at least it's working.
