I have started my journey with Django and I am thoroughly loving it. I do have a question about namespaces which I hope someone will be able to help me with and explain why it works like that.
I understand namespaces are used to make sure that if you have two pages with the same name that the url and reverse function points to the right page. I have been trying to implement namespaces in a test app I am writing but have not been able to do it.
Here is what I have so far (This is without namespaces as I haven't been able to get it to work.
Extract from app urls.py
from django.urls import path, re_path
from . import views
urlpatterns = [
path('', views.index, name = "index"),
]
project urls.py
from django.contrib import admin
from django.urls import path, include, re_path
import gallery
urlpatterns = [
path('admin/', admin.site.urls),
path('accounts/', include('django.contrib.auth.urls')),
path('index/', include('gallery.urls')),
]
And lastly, this is my view.py file in my app folder
from django.shortcuts import render
from django.urls import reverse
# Create your views here.
def index(request):
return render(request,"gallery/index.html")
Any help will be appreciated
URL namespaces allow you to uniquely reverse named URL patterns even if different applications use the same URL names. It’s a good practice for third-party apps to always use namespaced URLs (as we did in the tutorial). Similarly, it also allows you to reverse URLs if multiple instances of an application are deployed. In other words, since multiple instances of a single application will share named URLs, namespaces provide a way to tell these named URLs apart. See URL namespaces
In your case:
project urls.py
from django.contrib import admin
from django.urls import path, include, re_path
import gallery
urlpatterns = [
path('admin/', admin.site.urls),
path('accounts/', include('django.contrib.auth.urls', namespace='your-namespace')),
path('index/', include('gallery.urls',namespace='your-namespace')),
]
Extract from app urls.py
from django.urls import path, re_path
from . import views
app_name = 'app'
urlpatterns = [
path('', views.index, name = "index"),
]
in the template:
{% url 'app:index' %}

I am very new to django and beginning to understand some of the framework however view-route binding is confusing me
There is a persistent issue that when I try to visit any url except for the homepage and /admin I receive a 404, including routes I have declared in my project's urls.py file
also i am following this mdn tutorial
project urls.py
"""trends URL Configuration
The `urlpatterns` list routes URLs to views. For more information please see:
https://docs.djangoproject.com/en/2.2/topics/http/urls/
Examples:
Function views
1. Add an import: from my_app import views
2. Add a URL to urlpatterns: path('', views.home, name='home')
Class-based views
1. Add an import: from other_app.views import Home
2. Add a URL to urlpatterns: path('', Home.as_view(), name='home')
Including another URLconf
1. Import the include() function: from django.urls import include, path
2. Add a URL to urlpatterns: path('blog/', include('blog.urls'))
"""
from django.contrib import admin
from django.urls import path, include
from django.views.generic import RedirectView
from django.conf import settings
from django.conf.urls.static import static
urlpatterns = [
path('admin/', admin.site.urls),
path('articles/', include('articles.urls')),

path('', views.index, name='index'),

app named 'articles' views.py
from django.shortcuts import render
from django.http import HttpResponse
def index(request):
return HttpResponse("Hello, world. You're at the articles index.")
and here is the 404 page I receive
I know this is becoming very long but there is one more odd thing, when I refresh the 404 page, it will toggle between showing me the above screenshot and sometimes show me an old route which is no longer in the urls.py like this
this is on an nginx server with gunicorn, and restarting the nginx service does not solve the issue
In your projects urls.py you have defined
path('articles/', include('articles.urls')),
So by going to YOUR_URL/articles will not give a valid response. Instead try going to YOUR_URL/articles/ or change your path to
path('articles', include('articles.urls')),
Stumbled upon this SO post which lead me to the idea to restart gunicorn and that solved my problem so try running
sudo service gunicorn restart
should fix your problems
This is probably pretty simple but I can't get my head around it. I'm learning Django, have v3.0.4 installed and can't get the URLs from an app to work correctly.
On the project urls.py I have the following:
Project\urls.py:
from django.contrib import admin
from django.urls import path
from django.urls import include
from AppTwo import views
urlpatterns = [
path('', views.index, name='index'),
path('', include('AppTwo.urls')),
path('admin/', admin.site.urls),
]
I've created an app named "AppTwo" and have the following urls.py and views.py in the app:
AppTwo\urls.py:
from django.urls import path
from . import views
urlpatterns = [
path('/help', views.help, name='help'),
]
AppTwo\views.py:
from django.shortcuts import render
from django.http import HttpResponse
# Create your views here.
def index(request):
return HttpResponse("<em>My Second App</em>")
def help(request):
return HttpResponse("<em>Help Page!!!</em>")
If I browse to http://127.0.0.1:8000/ the index page loads and I see the text "My Second App" as expected. However if I browse to http://127.0.0.1:8000/help I get page not found 404 error.
I can also browse to the admin page just fine. So far this is a stock project, the only other change I made after creating it was to the settings.py file to install the "AppTwo" application. Based on the documentation, this looks like it should work, so what am I doing wrong?
yep, knew it was simple.
Changed
path('/help', views.help, name='help'),
to:
path('help/', views.help, name='help'),
all good now.
I am trying to build an API of my blogging website using Django rest framework, but my URL is not matching.
I am trying Django Rest framework for the first time so I am not quite able to fix this. But I think I mess this up in url_patterns.
Here is my URL code from the main directory(the directory which contains settings.py) .
`
from django.conf.urls import url,include
from django.contrib import admin
from django.urls import path, include
from blog import views
from rest_framework import routers
router = routers.DefaultRouter()
router.register(r'apipost',views.PostViewSet)
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'',include('blog.urls')),
path('api-auth/',include('rest_framework.urls',namespace='rest_framework')),
]
`
I am trying url http://127.0.0.1:8000/apipost and expect to get value in json format.
You need to add router.urls to your urlpatterns.
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'',include('blog.urls')),
path('api-auth/',include('rest_framework.urls',namespace='rest_framework')),
]
urlpatterns += router.urls
Django REST Framework Won't magically register your router in urlpatterns, you have to do it by yourself. You can use urlpatterns += router.urls if you want to add them to the root of your urlpatterns, or url(r'^api/', include((router.urls, 'app_name'))), if you want to set subpath for them.
i'm learning django and i'm making a blog tutorial but it's from older version that i have, i have version 2.0.2 and i'm not understand documentation my problem is that i dont know how configure my urls.py
this is my three proyect:
i need to put archive.html in 127.0.0.1:8000/ and this is my urls code
codigofacilito/blog.urls.py :
"""codigofacilito URL Configuration

from django.contrib import admin<br/>
from django.urls import path<br/>
from . import views<br/>
urlpatterns = [
path('admin/', admin.site.urls),
]
and codigofacilito/codigofacilito.urls.py:
from django.contrib import admin
from django.urls import path
from . import views
enter code here`urlpatterns = [
path('admin/', admin.site.urls),
]
from django.views.generic import TemplateView
urlpatterns = [
path('', TemplateView.as_view(template_name = 'archive.html')),
path('admin/', admin.site.urls),
]
put this in your project's urls.py, this will directly render the archive.html when you visit 127.0.0.1:8000/ in your browser.
but if you want to render data from backend in this html page then i suggest you to use views (function based , class based, etc..)
then you just have to import the views in url file and specify path for that.
from your_app.views import your_view
urlpatterns = [
path('/', your_view),
]
[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
