Django: URL Path not found jumps into next app-CodePudding

I have two apps:

backend shop

I my urls in main app dir:

path('backend/', include('backend.urls')),
path('', include('shop.urls')),

the problem is if I write in my url: localhost:8000/backend/abc which not exist Django jumps over to shop.urls and the app is crashing because it can not find the slug and the query goes in fail.

How can I prevent if I go to the url /backend/somethingwhichnotexist is returning an 404 and not search in other app urls for this folder? I have thought that this is one of the main reason for split the urls in app folders.

Here are some urls from backend/urls.py:

from django.urls import path, re_path
from . import views as backend_views
from django.contrib.auth import views as auth_views
from froala_editor import views
from django.conf.urls import include
urlpatterns = [
path('stamdata/', backend_views.edit_masterdata),
path('praefikser/', backend_views.edit_prefixes),
path('leverandorer/', backend_views.suppliers_view),
path('leverandorer/add', backend_views.add_supplier),

]

handler404 = 'backend.views.page_not_found_view'

shop/urls.py

here the url stops:

path('<slug:category_slug>/<slug:slug_subcategory>/', butik_views.cat_or_article),

normally I don't want that a backend urls switches to frontend view

You you said Django run through all of the URL patterns and stops till it finds its matching URL. SO, what has happen here is that when you type a URL with localhost:8000/backend/abc/ it runs through all the URLS before returning 404 to the client. So, it stops at the URL that support any string with 2 parameters in your case below URL.

path('<slug:category_slug>/<slug:slug_subcategory>/', butik_views.cat_or_article),

To get a 404 by adding a static word in you URL.

path('shop/<slug:category_slug>/<slug:slug_subcategory>/', butik_views.cat_or_article),

path('backend/', include('backend.urls')),
path('shop/', include('shop.urls')),

For now I fixed it with

shop/views.py

if category_slug == 'backend':
    response = render(
        request,
        'backend/404.html',
    )
    response.status_code = 404
    return response
else:

until I found another solution. It looks like that the URL dispatcher is working like this:

Django runs through each URL pattern, in order, and stops at the first one that matches the requested URL, matching against path_info.

So for now I did not found another way.

Edit:

I added this in the end of backend/urls.py:

re_path(r'^.*/$', backend_views.page_not_found_view)

so after all working urls it goes to all other to the 404 view.
