Please don’t add questions to old topics; instead please open a new topic for your question. In doing so you get a few suggestions for topics that might answer your question.
Another thing: when posting error messages, it helps to post them as Preformatted Text (see the </> button at the top of the Edit window); otherwise, important details like asterisks ‘*’ or underscores ‘_’ get converted to Markup tags, so that “self._home” shows up as “self.home”. This both looks odd and is incorrect.
I created a new topic with an attempt at an answer for your question here.
