Django regex not working when adding other branches to url-CodePudding

I am a complete beginner in Django, and I have encountered a problem while trying to set up a url for each "room". Here is the code:

from django.conf.urls import url
from . import views

urlpatterns = [
    url(r'^home/$', views.home, name='home'),
    url(r'^room/<str:pk>/$', views.room, name='room'),

]

Everything was working perfectly, until I add /<str:pk>/$. I have also add this code in the views.py section:

def room(request,pk):
    return render(request, 'base/room.html')

However I still get an error when loading the website. Image of the error message

Does someone know how to make it work?

Firstfully, as said in comments, you have to put pk in url and follow that:
```
http://127.0.0.1:8000/room/1/
```
Then, make sure you have at least one Room object in database, otherwise the url will not be active.
Last thing, it should be rather <int:pk> than str, because I believe your pk is a classic id as a number. So urls:
```
urlpatterns = [
    ...
    url(r'^room/<int:pk>/$', views.room, name='room'),

]
```

Just replaced /<str:pk>/$ by /(?P<pk>\d )/$', views.room, name='room'), and worked out perfectly !
