Specifying a namespace in include() without providing an app_name - django

models.py
from django.conf.urls import include, url
app_name = "Review"
urlpatterns = [
url(r'^books/', include("Review.urls", namespace='reviews')),
]
Review\urls.py
from django.conf.urls import include, url
from django.contrib import admin
from .views import (
ReviewUpdate,
ReviewDelete,
)
urlpatterns = [
url(r'^reviews/(?P<pk>\d+)/edit/$', ReviewUpdate.as_view(), name='review_update'),
url(r'^reviews/(?P<pk>\d+)/delete/$', ReviewDelete.as_view(), name='review_delete'),
]
I am providing app_name before my urlpatterns. But it's giving me error while running my code. The errors are given below:
File "E:\workspace\python\web\Book_Review_App\Book\urls.py", line 13, in <module>
url(r'^books/', include("Review.urls", namespace='reviews')),
File "E:\workspace\python\web\Book_Review_App\venv\lib\site-packages\django\urls\conf.py", line 39, in include
'Specifying a namespace in include() without providing an app_name '
django.core.exceptions.ImproperlyConfigured: Specifying a namespace in include() without providing an app_name is not supported. Set the app_name attribute in the included module, or pass a 2-tuple containing the list of patterns and app_name instead.
Please help.

The app_name needs to be set in your app's urls.py not the main urls.py.
In review.urls.py add the following,
from django.conf.urls import include, url
from django.contrib import admin
from .views import ( ReviewUpdate, ReviewDelete, )
app_name = 'Review'
urlpatterns = [
url(r'^reviews/(?P<pk>\d+)/edit/$', ReviewUpdate.as_view(), name='review_update'),
url(r'^reviews/(?P<pk>\d+)/delete/$', ReviewDelete.as_view(), name='review_delete'),
]
and remove the app_name from the main urls
EDIT: for the admin issue that the op mentioned in the comments,
in the main urls.py
from django.urls import path
urlpatterns = [
path('admin/', admin.site.urls),
]

You need to define app_name in urls.py and pass urlconf_module in tuple . Here is example
app_name = "example"
from typing import NamedTuple
class NamedURL(NamedTuple):
urlconf_module: None
app_name: None
daily_urls = NamedURL(<your custom urls in list>, "example")
urlpatterns = [
...
re_path(r'^daily/', include(daily_urls, namespace='daily')),
]

(Django) include does not import other apps' urls

In my Django project I have 2 apps: core and books. In my core/urls.py, I use python include('books.url') to import the urls from books/urls.py, but I keep getting this error
I have been having this issue now that's bugging me. I had a workaround for it, though I really want to fix this.
core/urls.py
from django.contrib import admin
from django.urls import path
from django.conf.urls import include
# local
urlpatterns = [
path('/', include('books.urls')),
path('admin/', admin.site.urls),
]
books/urls.py
from django.contrib import admin
from django.urls import path
# local
from graphene_django.views import GraphQLView
from books.schema import schema
urlpatterns = [
path('graphql/', GraphQLView.as_view(graphiql=True, schema=schema)),
]
As suggested by SO, I have:
put books.urls inside the single quotes ' '
placed the path('/', include('books.urls')) on top
switch from from django.urls import include to
from django.conf.urls import include
The only workaround I have is place all urls into the core/urls.py, but that seems too chunky in the long run. I don't get why include works for everyone but not me!
Could you help me with this issue? Thank you!
Now GraphQLView is called with the URL 127.0.0.1:8000/graphql/, if you want to call it with the URL 127.0.0.1:8000/, you need to change your code:
core/urls.py
from django.contrib import admin
from django.urls import path
from django.conf.urls import include
# local
urlpatterns = [
path('/', include('books.urls')),
path('admin/', admin.site.urls),
]
books/urls.py
from django.contrib import admin
from django.urls import path
# local
from graphene_django.views import GraphQLView
from books.schema import schema
urlpatterns = [
path('/', GraphQLView.as_view(graphiql=True, schema=schema)),
]

Django urls.py: passing dynamic url parameter into include()

I found in Django docs (https://docs.djangoproject.com/en/3.0/topics/http/urls/#passing-extra-options-to-include) that I can pass any constant into include() statement. Here in docs' example we are passing blog_id=3.
from django.urls import include, path
urlpatterns = [
path('blog/', include('inner'), {'blog_id': 3}),
]
But what if I want to pass dynamic url parameter into include()? I mean something like this:
from django.urls import include, path
urlpatterns = [
path('blog/<int:blog_id>/', include('inner'), {'blog_id': ???}),
]
Is it possible?
You do not specify the kwargs, so you write:
from django.urls import include, path
urlpatterns = [
# no { 'blog_id': … }
path('blog/<int:blog_id>/', include('inner')),
]
The url parameter will be passed to the kwargs of the included views.
This is to some extent discussed in the documentation on Including other URLconfs where it says:
(…) For example, consider this URLconf:
from django.urls import path
from . import views
urlpatterns = [
path('<page_slug>-<page_id>/history/', views.history),
path('<page_slug>-<page_id>/edit/', views.edit),
path('<page_slug>-<page_id>/discuss/', views.discuss),
path('<page_slug>-<page_id>/permissions/', views.permissions),
]
We can improve this by stating the common path prefix only once and
grouping the suffixes that differ:
from django.urls import include, path
from . import views
urlpatterns = [
path('<page_slug>-<page_id>/', include([
path('history/', views.history),
path('edit/', views.edit),
path('discuss/', views.discuss),
path('permissions/', views.permissions),
])),
]

Specifying a namespace in include() without providing an app_name ' django.core.exceptions.ImproperlyConfigured

This is my code. And i have a error....please help me....
'Specifying a namespace in include() without providing an app_name '
django.core.exceptions.ImproperlyConfigured: Specifying a namespace in include() without providing an app_name is not supported. Set the app_name attribute in the included module, or pass a 2-tuple containing the list of patterns and app_name instead.
You have to add a variable called app_name in the included urls.py module.
For example if you have this include in your project urls.py:
url(r'^bookmark/',include('bookmark.urls', namespace='bookmark'))
you have to add a variable:
app_name = 'bookmark'
just before the definition of urlpatterns variable in bookmark/urls.py file.
I didn't know where you i write app_name=blog.
However, i got it
Solution is going into the app file ex)/blog/urls.py
and then write app_name='blog'
$ cd /home/꾸르잼/Django/mysite/bookmark
$ vi urls.py
from django.conf.urls import url
from bookmark.views import BookmarkLV, BookmarkDV
app_name='bookmark'
urlpatterns = [
# Class-based views
url(r'^$', BookmarkLV.as_view(), name='index'),
url(r'^(?P<pk>\d+)/$', BookmarkDV.as_view(), name='detail'),
]
If you have a same problem like me, hopefully you can solve it as watching this.
Have a good day

Django URL mapping - NameError: name X is not defined

[A similar question was asked, but not marked as answered, here. I considered continuing that thread but the website told me I'm only supposed to post an answer, so it seems I have to start a new topic.] I'm trying to follow this tutorial and I'm having problems with the URL mapping. Specifically with the part described as "So best practice is to create an “url.py” per application and to include it in our main projects url.py file". The relevant, I hope, part of the folder structure, which arose by following steps of the tutorial to the letter (if possible; usage of the 'patterns' module was impossible for example) and using Django 1.10 is the following:
myproject/
myapp/
urls.py
views.py
myproject/
urls.py
The myproject/urls.py is as follows:
from django.conf.urls import include, url
from django.contrib import admin
admin.autodiscover()
from myapp.views import hello
urlpatterns = [
url(r'^admin/', include(admin.site.urls)),
url(r'^myapp/', include(myapp.urls)),
]
The myapp/urls.py is as follows:
from django.conf.urls import include, url
urlpatterns = [
url(r'^hello/', myapp.views.hello),
]
The myapp/views.py is as follows:
from django.shortcuts import render
def hello(request):
return render(request, "hello.html", {})
However, running 'python manage.py runserver' results in the following error:
url(r'^myapp/', include(myapp.urls)),
NameError: name 'myapp' is not defined
INSTALLED_APPS in settings.py contains 'myapp'.
I'd be greatful for any tips on how to deal with the NameError! [Or any tips whatsoever that anyone might consider to be helpful!]
You have the NameError because you are referencing myapp in myproject/urls.py but haven't imported it.
The typical approach in Django is to use a string with include, which means that the import is not required.
url(r'^myapp/', include('myapp.urls')),
Since you have move the hello URL pattern into myapp/urls.py, you can remove from myapp.views import hello from myproject/urls.py.
Once you've made that change, you will get another NameError in myapp/urls.py. In this case, a common approach is to use a relative import for the app's views.
from django.conf.urls import url
from . import views
urlpatterns = [
url(r'^hello/$', views.hello),
]
Make sure you have imported following modules to urls.py.
from django.conf.urls import url
from django.contrib import admin
in django 2.0
use these
from django.contrib import admin
from django.urls import path
from first_app import views
urlpatterns = [
path('',views.index, name="index"),
path('admin/', admin.site.urls),
]
your app URL has to be a string
so, here is how the code should look like.
from django.conf.urls import include, url
from django.contrib import admin
admin.autodiscover()
from myapp.views import hello
urlpatterns = [
url(r'^admin/', include(admin.site.urls)),
url(r'^myapp/', include('myapp.urls')),
]
also, note that from python 2 upward the regular expression is not needed.
change URL to path
from django.conf.URLs import include path
from Django.contrib import admin
admin.autodiscover()
from myapp.views import hello
urlpatterns = [
path('^admin/', include(admin.site.urls)),
path('^myapp/', include('myapp.urls')),
]
In Django 2.1.7 here is the default urls .py file
from django.contrib import admin
from django.urls import path
urlpatterns = [
path('admin/', admin.site.urls),
]
so we need to add this line as well
from django.conf.urls import url
I have followed #Alasdair answers
You have the NameError because you are referencing myapp in myproject/urls.py but haven't imported it.
The typical approach in Django is to use a string with include, which
means that the import is not required.
Unfortunately, it didn't work out(I still got the name X is not defined error). Here is how I do it.
from django.contrib import admin
from django.urls import include
from django.conf.urls import url
from article import urls as article_users
from article import urls as user_urls
urlpatterns = [
path('admin/', admin.site.urls),
path('api/article/', include(article_users)),
path('api/user/', include(user_urls)),
]
Before using the URL command be sure to first import the url from the module Urls. Then try using the runserver.
from django.conf.urls import url
from django.contrib import admin
from django.urls import path

TypeError: view must be a callable or a list/tuple in the case of include()

I am new to django and python. During url mapping to views i am getting following error:
TypeError: view must be a callable or a list/tuple in the case of include().
Urls. py code:-
from django.conf.urls import url
from django.contrib import admin
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^posts/$', "posts.views.post_home"), #posts is module and post_home
] # is a function in view.
views.py code:-
from django.shortcuts import render
from django.http import HttpResponse
# Create your views here.
#function based views
def post_home(request):
response = "<h1>Success</h1>"
return HttpResponse(response)
Traceback
In 1.10, you can no longer pass import paths to url(), you need to pass the actual view function:
from posts.views import post_home
urlpatterns = [
...
url(r'^posts/$', post_home),
]
Replace your admin url pattern with this
url(r'^admin/', include(admin.site.urls))
So your urls.py becomes :
from django.conf.urls import url, include
from django.contrib import admin
urlpatterns = [
url(r'^admin/', include(admin.site.urls)),
url(r'^posts/$', "posts.views.post_home"), #posts is module and post_home
]
admin urls are callable by include (before 1.9).
For Django 1.11.2
In the main urls.py write :
from django.conf.urls import include,url
from django.contrib import admin
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^posts/', include("Post.urls")),
]
And in the appname/urls.py file write:
from django.conf.urls import url
from . import views
urlpatterns = [
url(r'^$',views.post_home),
]
Answer is in project-dir/urls.py
Including another URLconf
1. Import the include() function: from django.conf.urls import url, include
2. Add a URL to urlpatterns: url(r'^blog/', include('blog.urls'))
Just to complement the answer from #knbk, we could use the template below:
as is in 1.9:
from django.conf.urls import url, include
urlpatterns = [
url(r'^admin/', admin.site.urls), #it's not allowed to use the include() in the admin.urls
url(r'^posts/$', include(posts.views.post_home),
]
as should be in 1.10:
from your_project_django.your_app_django.view import name_of_your_view
urlpatterns = [
...
url(r'^name_of_the_view/$', name_of_the_view),
]
Remember to create in your_app_django >> views.py the function to render your view.
You need to pass actual view function
from posts.views import post_home
urlpatterns = [
...
url(r'^posts/$', post_home),
]
This works fine!
