This is doing exactly what you tell it. You've set pages to be a class attribute of ParentMixin, which means it will also be a class attribute of any view class you mix it in to. Class attributes are shared across all instances of the class within a process, and since a process lasts across many requests, the data will persist across those requests.

You should always set attributes on self, which means doing it inside a method, in this case probably inside get_context_data. Django goes to some lengths to ensure that instance data is not shared in class-based views, but this does not apply to class-level data.
