I'm trying Django 1.11 and I have an issue :
This my file agora/agora/urls.py :
from django.conf.urls import url, include
from django.contrib import admin
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^start/', include('start.urls', namespace='start')),
]
And this is my file agora/start/urls.py
from django.conf.urls import url
from . import views
urlpatterns = [
url(r'^$', view_first, name='view_first'),
url(r'^/inscription', view_second, name='view_second'),
url(r'^/about', view_about, name='view_about'),
]
The Django server return an error :
NameError: name 'view_first' is not defined
Many thanks for your answers !
You should do like this for all functions
views.view_first
views.view_second
....
you have to specify the function name in the import statement
from django.conf.urls import url
from .views import view_first, view_second, view_about
urlpatterns = [
url(r'^$', view_first, name='view_first'),
url(r'^/inscription', view_second, name='view_second'),
url(r'^/about', view_about, name='view_about'),
]
or import the view and assign each function with view.
from django.conf.urls import url
from . import view
urlpatterns = [
url(r'^$', view.view_first, name='view_first'),
url(r'^/inscription', view.view_second, name='view_second'),
url(r'^/about', view.view_about, name='view_about'),
]
Although, the question has already been answered, I did happen to notice a minor but mistake.
When writing urls, adding "$" sign at the end of the endpoint is always recommended. Not adding the same may cause overlapping of similar urls which could confuse the app behaviour and even can cause some serious errors.
The dollar sign marks the end of the url string.
Just a heads up!!

'C:\Users\huihuiqian\mys ite\posts\urls.py'>' does not appear to have any patterns in it. If you see valid patterns in the file then the issue is probably caused by a circular import.
mysite.urls.py
from django.conf.urls import url, include
from django.contrib import admin
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^posts/', include('posts.urls')),
]
post.urls.py
from django.conf.urls import url
from . import views
urlpartterns =[
url(r'^$',views.index, name='index')
];
In my urls.py I have this.
from django.conf.urls import include, url
from django.contrib import admin
from django.conf import settings
from django.conf.urls.static import static
from events import views as eviews
urlpatterns = [
url(r'^user/', include('accounts.urls')),
url(r'^admin/', include(admin.site.urls)),
url(r'^$', eviews.events_list, name='events_list'),
url(r'^(?P<o_type>[-\w]+)/$',
eviews.events_list,
name='events_list_by_org'),
url(r'^(?P<id>\d+)/(?P<slug>[-\w]+)/$',
eviews.event_detail, name='event_detail'),
]
when I add the "user" url which is at first line in urlpatterns, it shows error on line 26 which is "events_list_by_org" url. When I comment out or remove 'user' url it works fine but shows error when it's included.
Try separating your event urls like your accounts url inside account app, and adding namespece to accounts and events.
urls.py in core
urlpatterns = [
url(r'^user/', include('accounts.urls', namespace='accounts')),
url(r'^event/', include('event.urls', namespace='event')),
]
urls.py in event app
urlpatterns = [
url(r'^$', eviews.events_list, name='events_list'),
url(r'^(?P<o_type>[-\w]+)/$',
eviews.events_list,
name='events_list_by_org'),
url(r'^(?P<id>\d+)/(?P<slug>[-\w]+)/$',
eviews.event_detail, name='event_detail'),
]
Maybe it's because of follwoing namespaces, so trying your namespace to user urls.
I am very new, and I am doing a tutorial, that is a little bit old. I keep getting an error that this cannot import name 'patterns' then something about include, then syntax and so on. So what is wrong this section? How would I write it current day? Thank you for your time.
from django.conf.urls import patterns, include, url
from django.contrib import admin
from djangonote.views import home_view
urlpatterns = patterns('',
url(r'^$', home_view, name='home'),
url(r'^notes/', include('notes.urls', namespace='notes')),
)
The reply below fixed that issue, thank you Exprator!
I now get the issue:
NameError: name 'notes' is not defined.
What does that mean?
Ty for your time.
from django.conf.urls import include, url
from django.contrib import admin
from djangonote.views import home_view
urlpatterns = [
url(r'^$', home_view, name='home'),
url(r'^notes/', include('notes.urls', namespace='notes')),
]
[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
from django.conf.urls import url, patterns, include
from django.contrib import admin
from django.views.generic import TemplateView
from collection import *
#from collection.views import index,thing_detail,edit_thing
urlpatterns = [
url(r'^$', views.index, name='home'),
url(r'^about/$',TemplateView.as_view(template_name='about.html'),name='about'),
url(r'^contact/$',TemplateView.as_view(template_name='contact.html'),name='contact'),
url(r'^things/(?P<slug>[-\w]+)/$', 'views.thing_detail' ,name='thing_detail'),
url(r'^things/(?P<slug>[-\w]+)/edit/$', 'views.edit_thing',name='edit_thing'),
url(r'^admin/', include(admin.site.urls)),
]
After running the server there is an error "NameError: name 'views' is not defined"
Any help ??
You aren't importing your own views.
Try adding this to your urls.py:
from . import views
Or if you are importing them from a specific app, try replacing . with the app name
First thing I notice is the import *, realize that this will/can cause confusion for other Developers reading your scripts. Python has a methodology that insists that explicit is better than implicit. Which in this senario means you should be explicit about what you are importing.
from django.conf.urls import url, patterns, include
from django.contrib import admin
from django.views.generic import TemplateView
from collection import views as collection_views
urlpatterns = [
# Function Based Views
url(r'^$', collection_views.index, name='home'),
url(r'^things/(?P<slug>[-\w]+)/$', collection_views.thing_detail ,name='thing_detail'),
url(r'^things/(?P<slug>[-\w]+)/edit/$', collection_views.edit_thing,name='edit_thing'),
# Class Based Views
url(r'^about/$',TemplateView.as_view(template_name='about.html'),name='about'),
url(r'^contact/$',TemplateView.as_view(template_name='contact.html'),name='contact'),
# Admin
url(r'^admin/', include(admin.site.urls)),
]
Here instead of importing everything from collection I'm importing just your views and assigning them to a variable. Then using that variable in the URL definitions.
Be sure to import your views by
specifying its location and the methods inside the view to be imported on your urls.py.
from . collection import *
(line above means from current location find collection.py and import everything on it)
Happy coding!
