AttributeError: type object has no attribute 'as_view' using docker-compose
Question
I am new to Docker and am trying to create a simple form to be built with Docker and displayed through my localhost. When I try to sudo docker-compose up , I get the error AttributeError: type object 'UserForm' has no attribute 'as_view' . I was under the impression that I would be able to see the immediate result on my localhost:5002.

I don't know much about Flask, but I use Django and they appear to be similar in this case.
You are trying to render the view using the UserForm , while you should be rendering a view (in your case the index.php), with the form inside a context variable, and then render the form fields inside the html file.
--edit-- some help with views: http://flask.pocoo.org/docs/0.12/tutorial/views/
