Build Your Routes

I get this mistake when rerunning the server after adding to the urlpatterns:

File “<frozen importlib._bootstrap>”, line 1006, in _gcd_import File “<frozen importlib._bootstrap>”, line 983, in _find_and_load File “<frozen importlib._bootstrap>”, line 965, in _find_and_load_unlocked ModuleNotFoundError: No module named ‘projects.urls’

My guess from looking at your traceback is that you are somewhere referencing a urls.py file in a projects app folder that might not exist or be incorrectly linked.

I had a similar issue as Pygator when using ‘projects.urls’. The following seemed to solve the issue.

(in portfolio/urls.py)

from django.contrib import admin
from django.urls import include, path
from projects import urls

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

Hello again, thanks for your comments. @Pygator, as a follow-up: did you make sure that the file projects/urls.py exists? You shouldn’t have created it yet at the beginning of this video, that’s why at ~3:11 I am handling the same error that you are talking about. This is expected if the file doesn’t exist yet, since Django can’t find the (non-existent) file.

@Jon Lee: In your case you already created the file, since you are able to import it in the way you showed. I would suggest, however, to stick with the way that Django proposes to handle the import:

path('projects/', include('projects.urls')

This avoids the necessity to import the file explicitly.

I assume that you were running into a different issue than @Pygator. Can you give it another go with the proposed way of linking to the app’s urls.py file that is mentioned in the video and in this post, and follow-up with the exact error message you are receiving, in case you run into one?

Please note that 'projects.urls' is indeed a string.

Hi Martin. I was running into another issue but that seems to have been solved now that you pointed out that ‘projects.urls’ is supposed to be a string. I didn’t wrap that section in quotes first time around. Thank you :)

Great, glad to here you managed to fix it! 👏

Hi, Martin. When I tried to run the server, it gave me the error:

March 19, 2020 - 18:39:33
Django version 3.0.4, using settings 'portfolio.settings'
Starting development server at http://127.0.0.1:8000/
Quit the server with CONTROL-C.
Not Found: /
[19/Mar/2020 18:39:42] "GET / HTTP/1.1" 404 2033

However, I did implement

from django.contrib import admin
from django.urls import include, path

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

correctly as you did in porfolio/urls.py. Can you help me to fix this error? Thank you very much.

If you look closely at the error, it tells you what URL path it didn’t find:

Not Found: /

You did not create a urlpattern for the empty base URL (and neither did I when building out the project). So in short: your error is expected and if you navigate to one of the defined urlpatterns (/admin or /projects) you should see a page pop up :)

It works. Thanks Martin.

after you import views you restart your server in the terminal, how do you do it? i cant write in my terminal. i have AttributeError: module ‘projects.views’ has no attribute ‘project_list’ and under its the blinking square but i cant write . how do you do that??

Hi @budescueftimie. Sometimes the development server gets stuck on an error. You can stop it by pressing Ctrl+D or Ctrl+C - or simply by closing your terminal window and opening up a new one.

Restart the server - and you should be good to go :)

thank you, Ctrl+C works, i did not want to have to close and open a new terminal window everytime i get stuck in an error.

@budescueftimie If your keyboard has a function key, hold Ctrl+function and find the BREAK key and press it. The server should then release.
