Python 3.8.5

Running python3 manage.py runserver returns me this error

Hello, thank you for opening the issue. Can you use text instead of image so we have the full stacktrace and it's searchable and readable by text to speech software ? :)

Got the same issue. When I remove it from the urlpatterns, it stops.

RecursionError: maximum recursion depth exceeded while calling a Python object

I had the same problem an hour ago when I started looking at the django-survey package.

I think by naming your django app 'survey', you will include the survey.urls recursively, without breaking the loop.

I'm not yet sure what the proper way is to use the survey package, but I now have the impression that you shouldn't name your app 'survey', and maybe should clone/copy the 'survey' folder from the repository.

But this could be a very noob impression. And the getting-started could be a bit more monkey-proof for me.
The getting started could include the steps needed to create the example django project and app(s), and copy/clone (parts of) the survey repo in your code.

It should work like a standard Django app (but maybe it isn't right now).
