is this challenge broken? https://teamtreehouse.com/library/django-basics/what-a-view/first-url

So I was just trying to wrap up some of the quizzes I skipped over. Either I'm totally not tracking today, or this challenge is broken?

newspaper/urls.py 
from django.conf.urls import url
from . import views

urlpatterns = [
    path('', index)
]

I haven't been through any Django stuff, and I kind of suck at regex. So unfortunately I won't be able to go into too much detail about why this is true, or any more advanced expressions, but...

My understanding is that path('', index) isn't strictly defining an empty string. I think you need r'^$' to ensure you're matching an entirely empty string. When Django encounters an empty string, I believe it will go to the index page.

Trying that along with making sure to reference views.index fixed it for me. Sorry I can't more clearly explain why this works, but maybe it will trigger your memory. 😅

url(r'^$', views.index)

That would make sense. I've been using almost exclusively on 3.0 and up.... no regex in the URLs needed if you have an empty path there!

I can definitely understand that. Trying to remember how to write normal JavaScript when I've used jQuery simple syntax for so long is tough - I forget all the extra stuff you need to explicitly write.
