30432	Django development server shutdown on error	User632716	nobody	"As in my question on SO [here](https://stackoverflow.com/questions/55953263/django-development-server-shutdown-on-error) I am running a dev server on localhost to test a django app. About a week ago the dev server started exiting on error- which is not ideal.

To give you an instance, imagine I want to create a new view, I make my template, then I add the following in urls:


  urlpatterns = [
    ...
    path('forgotten-password', ForgottenPassword.as_view(), name='forgotten_password'),
  ]

I haven't yet created the ForgottenPassword class based view yet, so rightly the server throws the error:

  File ""/code/accounts/urls.py"", line 19, in <module>
    path('forgotten-password', ForgottenPassword.as_view(), name='forgotten_password'),
  NameError: name 'ForgottenPassword' is not defined

The server then quits however. This is not the desired behavior. I expect the server to remain in an error state until i fix the error (this happened up to about a week ago).  It was around the same time that we upgraded from django 2.1 to 2.2, is this a desired behaviour in 2.2?"	Uncategorized	new	Uncategorized	2.2	Normal		dev-server devserver		Unreviewed	0	0	0	0	0	0
