Django 2 error: Specifying a namespace in include() without providing an app_name about deux HOT 7 OPEN

Can you provide a code example? Because as I'm typing app_name="sth" in urls.py it doesn't work.

Let's say in your main urls.py you want to include the urls of an app, called shop_app, like this:
path("shop/", include("shop_app.urls", namespace='shop')),

Then, in your urls.py file of your shop_app located in shop_app/urls.py, after the urlpatters add the app_name like this:

urlpatterns = [
   ... some patterns
]

app_name = 'shop'

If you don't have access to the shop_app urls, as in case you are using an included package, then you'll have to drop the namespace from your main include and remove the namespace references from your url tags, or from your reverse functions.

Or you can also use it this way:

path('mfa/', include(("deux.urls", 'app_name'), namespace="mfa")),

from deux.

Use app_name='nameapp'
in urls for applications, after urlpatterns

from deux.

as indicated by @DonExo

path('', include(('blog.urls', 'blog'), namespace='blog'))

from deux.

Excelent ¡¡¡

from deux.

with which value?
