The Django Djitney

I am currently working on the django project and for some reason my code will not run on the localhost server. I started having problems after the first few steps when I imported things. I kept going thinking I just would not be able to see the progress but step 12 actually has me click a button on the server itself to add information. If it will not load, than I cannot complete it.

I lined up my code with the Youtube solution. Am I missing something?

  form_class = "LineForm"
# Create View creates a new record in the database using a provided Django form. It handles both GET (displaying the form) and POST(processing the submitted data) requests.

# step 9
class UpdateLineView(UpdateView):
  model = Line
  template_name = 'routes/update_line.html'
  form_class = LineForm

# step 10

  success_url = "/lines"
# There are files in the routes folder for create, update, and delete.
