So, I am writing code with Python and Django (and other web dev requirements).
from django.urls import path
from . import views
urlpatterns = [
path("", views.index, name="index"),
path('wiki/<str:name>/', views.info, name="info"),
path("create", views.create, name="create"),
path("results", views.search, name="search"),
path("wiki/<str:name>/edit", views.edit, name="edit")
]
The problem I am facing is that in path("wiki/<str:name>/edit", views.edit, name="edit"), I get an error:
NoReverseMatch at /wiki/Django/>
Reverse for 'edit' with no arguments not found. 1 pattern(s) tried: ['wiki/(?P[^/]+)/edit$']>
And I want to refer to the url in path('wiki/<str:name>/', views.info, name="info")
Please help me fix the error

I have created a view at example.views.py, and here is my urls.py file:
from django.urls import path
urlpatterns = [
path('/', example.views.index, name='index'),
]
However, when I run django's runserver, I get the following error:
path('/', example.views.index, name='index'),
NameError: name 'example' is not defined
What do I need to do to fix this? Quoting the view doesn't help either.
Try changing it to:
from django.urls import path
from example import views
urlpatterns = [
path('/', views.index, name='index'),
]
I am very new to Django and I have created two apps in my project one is login & server_status. I have used the namespace method to access my login and server_status across both apps. It is working fine when I tried to access index but when I tried to access dashboard in server_status it is not working.
Reverse for 'server_status' not found. 'server_status' is not a valid view function or pattern name
# server_status URL
from django.urls import path
from . import views
urlpatterns = [
path('', include('server_status.urls', namespace='server_status')),
path('', include('login.urls', namespace='login')),
path('admin/', admin.site.urls),
]
# login app URL
app_name = 'login'
urlpatterns = [
path('login', views.index, name='index')
]
# project URL
from django.contrib import admin
from django.urls import include, path
app_name = 'server_status'
urlpatterns = [
path('', views.index, name='index'),
path('dashboard/', views.dashboard, name='dashboard'),
path('server_status/', views.server_status, name='server_status'),
path('request_access/', views.request_access, name='request_access'),
]
In server_status/templates/server_status/index.html
Login
I know this is very simple one, but it makes me very complicated.
In the posted code, you define urlpatterns twice, so the first set of urlpatterns is overridden by the second. Since server_status is defined in the first set, it is not present in memory, since you obliterate it in the second definition. index is the only pattern that survives. I think what you meant to do in the second stanza was to add to the urlpatterns with:
urlpatterns += [...]
To declare namespace you should do something like this:
# project URL
from django.contrib import admin
from django.urls import include, path
urlpatterns = [
path('', include('server_status.urls', namespace='server_status')),
path('', include('login.urls', namespace='login')),
path('admin/', admin.site.urls),
]
then you can use
Login
or
Server status index
I believe this is a simple question but I am having a hard time figuring out why this is not working.
I have a django project and I've added a second app (sales). Prior to the second app, my urls.py simply routed everything to the first app (chart) with the following:
urlpatterns = [
path('admin/', admin.site.urls),
path('', include('chart.urls')),
]
and it worked fine.
I have read the docs over and over a looked at many tutorials, so my impression is that I can simply amend the urls.py to include:
urlpatterns = [
path('admin/', admin.site.urls),
path('sales/', include('sales.urls')),
path('', include('chart.urls')),
]
and it should first look for a url with sales/ and if it finds that then it should route it to sales.urls, and if it doesn't find that then move on and route it to chart.urls. However, when I load this and type in 127.0.0.1:8000/sales, it returns the following error:
Page not found (404)
Request Method: GET
Request URL: http://127.0.0.1:8000/sales/
Raised by: chart.views.index
which tells me that it is not routing my sales/ url to sales.urls but to chart.urls. When I change path('', include('chart.urls')), to path('', include('sales.urls')), it does route it to sales.urls so I know that my sales.urls file is set up correctly.
I know this is probably an easy question but I cannot figure it out with anything I've read. Any help is appreciated.
chart.urls:
from django.urls import path, re_path
from . import views
urlpatterns = [
path('dashboard/', views.chart, name='dashboard'),
path('', views.index, name='index', kwargs={'pagename': ''}),
path('<str:pagename>/', views.index, name='index'),
]
sales.urls:
from django.urls import path
from . import views
urlpatterns = [
path('sales/', views.sales, name='Sales Dashboard'),
]
I think the correct url for the sales page in your case would be http://127.0.0.1:8000/sales/sales/.
This is because sales/ is then looking in the included sales.urls and not finding any urls at the root / (the only url included there is at sales/ (within sales/) so will be sales/sales/
Reply to an OLD question but may be useful for others...
from django.urls import path, include
dont for get to import include
Do this:
urlpatterns = [
url(r'^admin/', include(admin.site.urls)),
url(r'^', include('chart.urls')),
url(r'^sales/', include('sales.urls')),
]
you are not doing it properly since you are not telling your app where go once it is loaded .this r'^' to go directly to chart.url url(r'^', include('chart.urls')),
I am using Django version 1.10.7. Currently in my html I have:
</span>
My project urls.py has
from django.conf.urls import include,url
from django.contrib import admin
from base import views
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^team/', include('team.urls'), name='team'),
url(r'^game/', include('game.urls'), name='game'),
url(r'^about/', include('base.urls'), name='about'),
url(r'^$', views.home, name='home'),
]
And in views.py,
from django.shortcuts import render
# Create your views here.
def about(request):
return render(request,'base/about.html',{})
def home(request):
return render(request,'base/home.html',{})
This gives the error:
NoReverseMatch at /
Reverse for 'home' with arguments '()' and keyword arguments '{}' not found. 0 pattern(s) tried: []
Request Method: GET
Request URL: http://127.0.0.1:8000/
Django Version: 1.10.7
Exception Type: NoReverseMatch
Exception Value:
Reverse for 'home' with arguments '()' and keyword arguments '{}' not found. 0 pattern(s) tried: []
How can I fix this?
Try to put your urls in this order:
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^$', views.home, name='home'),
url(r'^team/', include('team.urls'), name='team'),
url(r'^game/', include('game.urls'), name='game'),
url(r'^about/', include('base.urls'), name='about'),
]
if works, it means that there is a problem in your other included urls files.
This seems like a common problem people are running into, but I can't figure it out for the life of me. I've set up a URL:
from django.conf.urls import url
from . import views
from django.contrib.auth import views as auth_views
urlpatterns = [
url(r'^login/$', views.login_view, name='login'),
url(r'^password_reset/$', auth_views.password_reset, name='password_reset'),
url(r'^password_reset_done/$', auth_views.password_reset_done, name='password_reset_done'),
url(r'^auth/$', views.login_auth, name='login_auth'),
url(r'^register/$', views.register_user, name='register'),
url(r'^logout/$', views.logout_user, name='logout'),
]
I try to link to the password_reset URL:
Forgot Password?
But it gives me the following error:
NoReverseMatch at /accounts/password_reset/
Reverse for 'password_reset_done' with arguments '()' and keyword arguments '{}' not found. 0 pattern(s) tried: []
This seems like a really simple bit of code, but it doesn't work. I can successfully call password_reset_done using this exact method, but for some reason it doesn't work with password_reset.
The password_reset line should look like this:
url(r'^password_reset/$', auth_views.password_reset, {'post_reset_redirect' : '/accounts/password_reset_done/'}, name='password_reset'),
