I think in step 4 of this exercise the hint forgets the include() function in the URLconf, or possibly I was just supposed to know to add it.

Original hint that did not work:
Include the vetoffice URLconf by adding path('', 'vetoffice.urls') to the urlpatterns in djangovet/djangovet/urls.py

Change to make the solution work:
Include the vetoffice URLconf by adding path('', *INCLUDE*('vetoffice.urls')) to the urlpatterns in djangovet/djangovet/urls.py .

# This does NOT work
urlpatterns = [
path(‘admin/’, admin.site.urls),
path(’’, include(‘vetoffice.urls’)),
]

# This works
urlpatterns = [
path(‘admin/’, admin.site.urls),
path(’’, include(‘vetoffice.urls’))
]

  1. This module wasn’t very straight forward. When I got to the last question it wasn’t clear what the difference between the two urls.py files was. I get the first but didn’t conceptually grasp how the parent urls.py file connects to the main.html. I understand now, with the ‘include’ designation that we are essentially connecting the two.

  2. Was having issues seeing the change upon running the server. I couldn’t find the admin or the home page and nothing loaded even after the successful completion of the exercise.

update: needed to add 0.0.0.0:4001 to the end of the ‘runserver’ command. Works now. Really want to understand these elements better.

Also having hard time understanding why we need to define url’s twice?

Changed in the main urls.py

urlpatterns = [
    path('admin/', admin.site.urls),
    path('home', include('vetoffice.urls'))
]

urls.py in vetoffice left unchanged:

urlpatterns = [
  path("", views.home)
]

When I go to http://localhost:4001/home I am still greeted with the welcome text. What’s the point of route parameter in vetoffice urls.py file?

Edit: Ok, I guess we have to do it twice because we want ‘apps’ to be independent so that we could import vetoffice to another project but still question remains - why route parameter is ‘ignored’ in vetoffice urls.py?

ok, finally got it. vetoffice urls.py holds subroutes.
