This declares a class attribute called context_var1, which initially has the value y. When you construct an instance of this class, this is copied to self.context_var1 > def form_valid (self, form): > ... > self.context_var1 = x This updates self.context_var1 > ... > def get_context_data(self, **kwargs): > ... > context['context_var1'] = context_var1 Here you are using the class attribute, rather than the instance attribute. The class attribute is never changed from y, only the instance attribute. You want self.context_var1 here. > ... > return context > > > As shown above, I update a set of context variables in form_valid and > I intend to use these in the template - hence the variables in context > dictionary.

Well, you've got to call the functions in the appropriate order. Try accessing the attribute via self, and see where that gets you.
