I'm a newbie in Django and just started looking at it before a day by installing Django 1.10 on my local.
I've followed all the instructions of this link https://docs.djangoproject.com/en/dev/intro/tutorial01/. However I'm continuously getting this error:
Page not found (404) Request Method: GET Request URL: http://127.0.0.1:8000/polls/
Using the URLconf defined in mysite.urls, Django tried these URL patterns, in this order:
^admin/
The current URL, polls/, didn't match any of these.
I've created polls app to getting started.
To make a start, I went with view.py, here is the code:
polls/views.py
from django.shortcuts import render
# Create your views here.
from django.http import HttpResponse
def index(request):
return HttpResponse("Hello World!")
Here is my code for urls.py:
polls/urls.py
from django.conf.urls import patterns, url
from . import views
urlpatterns = patterns('',
url(r'^$', views.index, name='index'),
)
And here is the urls.py in root:
mysite/urls.py
from django.conf.urls import patterns,include, url
from django.contrib import admin
urlpatterns = patterns('',
url(r'^polls/', include('polls.urls')),
url(r'^admin/', include(admin.site.urls)),
)
I've spent good piece of time to find out the solution, found that this question has been asked for many times,so tried with those solutions as well but none of them worked for me.
I can't find out what I'm missing here so please draw my attention to the gap.
I think you have edited the wrong file when trying to change the root url config.
Make sure you are editing the root url config in mysite/mysite/urls.py (the directory containing settings.py) not mysite/urls.py (the directory containing manage.py).
As general advice, install the latest release, currently 1.9. Don't use 1.10, which is under development. Make sure that you are following the tutorial for 1.9, because the tutorial changes for different versions. For example, your mysite/urls.py doesn't match the tutorial for 1.9, as the urlpatterns should be:
urlpatterns = [
url(r'^polls/', include('polls.urls')),
url(r'^admin/', admin.site.urls),
]
In settings.py you have a setting name INSTALLED_APPS-
Adds you app i.e. polls to it.
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
....
'polls',
]
It's working. Go to your url bar and type your app name:
http://127.0.0.1:8000/home
My app name is home. It will work.
If you want to set your app as your default page then import views from your app.
Like
from home import views
then write
url(r'^$', views.index),
inside.
It will set the views as your default page
http://127.0.0.1:8000/
When you type this it will redirect to your views.
I had the same problem as described. Running a Windows machine.
It turned out, that the virtual environment I was using had not been configured properly (or maybe I had forgot to activate it before installing Django) and the interpreter and django-admin were fetched from the wrong path by CMD.EXE.
If it appears as if Django is "ignoring" your urls.py - try deleting everything, re-creating the virtual environment, activating it and re-installing Django afterwards.
Make sure you have path("admin/", admin.site.urls) in your main url settings.
change the mysite/url
from django.conf.urls import patterns,include, url
from django.contrib import admin
urlpatterns = patterns('',
url(r'^&', include('polls.urls')),
url(r'^admin/', include(admin.site.urls)),
)
Then run your server and visit 127.0.0.1/8000.
This should take you to the index of your website.
or you leave your code as it is and run 127.0.0.1/8000/polls on your browser
if #Alasdair answer does not work, and it seems your working on correct files, just restart your server
The path in Django 2.2 does not support regular expression , I was using, path('(?P<id>\d+)/share/', views.mail_send_view) , so getting error, now changed to this, path('<int:id>/share/', views.mail_send_view). Now not getting any error. For more info please follow django's official documentation.
I too had same problem going through the official docs tutorial. I was using cloud 9. What I realised before I was able to solve this problem was that while creating the workspace I already chose django(ie by the time my workspace was created, django had already been installed) And going through the tutorial, I again executed $ django-admin startproject mysite thereby having another layer of django with multiple directories and unavoidably the confusion. My solution was to delete everything and start all over.

I am running a django project on a ubuntu digital ocean droplet with nginx/gunicorn on my own domain. I am using a virtual environment with Django version 3.1.6 and Python 3.8.5
I am trying to follow Corey Shafers Django tutorial to create a blog app and while I can reach the generic django success page on example.com I ran into the following from example.com/blog :
Page not found (404)
Request Method: GET
Request URL: example.com/blog
Using the URLconf defined in website.urls, Django tried these URL patterns, in this order:
admin/
The current path, blog, didn't match any of these.
My current ~/projectdir/website/urls.py (see edit at bottom):
from django.contrib import admin
from django.urls import path, include
urlpatterns = [
path('admin/',admin.site.urls),
path('', include('blog.urls')),
]
My ~/projectdir/blog/urls.py:
from django.urls import path
from . import views
urlpatterns = [
path('', views.home, name='blog-home'),
path('about/', views.about, name='blog-about'),
]
My ~/projectdir/blog/views.py:
from django.shortcuts import render
from django.http import HttpResponse
def home(request):
return HttpResponse('<h1>Blog Home</h1>')
As far as I can tell everything looks ok syntax-wise but I can't figure out why the URLconf is not seeing the blog path. I have tried reloading nginx and that didn't help.
EDIT
I have edited /projectdir/website/urls.py to look like this:
from django.contrib import admin
from django.urls import path, include
urlpatterns = [
path('admin/',admin.site.urls),
path('blog', include('blog.urls')),
]
I am still getting the same 404 reponse with "The current path, blog, didn't match any of these."
I think you have not included the blog app in your base urls.py, see this django doc.
Your virtual environment may not be enabled in Visual Studio code. Activate venv in vscode or other , then try again
you can activate venv in vscode by ctrl+shift+P -> select interpreter ->Select Interpreter path -> select your python that you want use it.
or you dont run your project in vscode and then run it
and then /polls request after localhost:8000 to the correct address will do
path('', include('blog.urls')) urls paths should written as path('blog/', include('blog.urls')).
This mean include path not be an empty string.
I'm a newbie to Django and I know this probably has been asked alot of times.
So basically what's happening is when I try to create a new project and whenever I'm trying to run my server, by default it's opening http://127.0.0.1:8000/catalog/ and not http://127.0.0.1:8000/.
Even if I run the server with my other projects, I'm facing the same error.
I followed this django basics tutorial on https://developer.mozilla.org/en-US/docs/Learn/Server-side/Django/skeleton_website
Idk but somehow I think it's default address is set to http://127.0.0.1:8000/catalog/.
Here's the link to the repo for the project:
https://github.com/Fanceh/django-404-error
Here's my project's urls.py:
from django.contrib import admin
from django.urls import path, include
from testuapp import urls
urlpatterns = [
path('admin/', admin.site.urls),
path('',include("testuapp.urls"))
]
Here's the code in my testuapp urls.py:
from django.urls import path
from . import views
urlpatterns = [
path('', views.testu),
]
Here's my webapp's views.py file:
from django.shortcuts import render
# Create your views here.
def testu(request):
render(request, 'Greetings!')
Is there any way I can change it?
Regards
From the tutorial link it mentions the redirect.
Any request for the root URL, will redirect you to /catalog.
Screenshot from the tutorial below.
HTH
so i assume you are below url pattern structure in your testuapp project.
urlpatterns = [
path('catalog',include("views.catalog"))
]
views.calalog is the name of the method in your view file.
Ok I think I figured it out, it's just the chrome cache. I cleared it and bam it's working!
I am working through a (mycodesmells) django tutorial and towards the bottom under "ADDING TO THE PROJECT" it says to update the url.py file with the code that it gives.
Once I update that file it crashes the server and gives me the error.
"No module named 'django_simple.todo'
I looked in SO posts and template view and redirect were mentioned in the following post.
1. Does this mean its deprecated?
2. How do i fix or adjust the code for Django 1.1 and Python 3
Templateview
from django.conf.urls import include, url
from django.contrib import admin
from django_simple.todo import views as todo_views
admin.autodiscover()
urlpatterns = [
url(r'^$', todo_views.index),
url(r'^admin/', include(admin.site.urls)),
]
Make sure you have an __init__.py file in the "todo" folder. That lets Python know it's a module.
Also make sure you have django_simple.todo in your Django apps list in your settings.py.
I followed the instructions in the tutorial
I made one change for debugging, here are the files:
mysite1\urls.py:
from django.conf.urls import include, url
from django.contrib import admin
urlpatterns = [
url(r'^abc/', include('polls.urls')),
url(r'^polls/', admin.site.urls),
url(r'^admin/', admin.site.urls),
]
File: mysite1\polls\urls.py
from django.conf.urls import url
from .import views
urlpatterns = [
url(r'^&', views.index, name='index'),
]
Now if I go to the site http://127.0.0.1:8000/polls/ then it shows the login page same as going to the site http://127.0.0.1:8000/admin/.
However, if I go to the site http://127.0.0.1:8000/abc/ it gives me the following:
Page not found (404)
Request Method: GET
Request URL: http://127.0.0.1:8000/abc
Using the URLconf defined in mysite1.urls, Django tried these URL patterns, in this order:
^abc/
^polls/
^admin/
The current URL, abc, didn't match any of these.
You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page.
Can someone guide me what I am doing wrong?
In mysite1\polls\urls.py It should be
url(r'^$', views.index, name='index'),
Notice that your code had an & instead of $. $ indicates a end-of-string match character.
I had a few issues with this, maybe it'll help someone. My VS code was running python 2.7 so the first line on page urls.py in the web project folder (not the polls folder) I had to change to "django.conf.urls import include, url" from "from "django.urls import include, path". I had to include .conf. and urls, path was not working and it was not working without "conf".
Another issue I had on this same page is I had to correct it to "urlpatterns = [url('', include('hello.urls'))..." from "urlpatterns = [path('', include("hello.urls"))". Path was not working so I got this to work.
The third thing is, Notice that there is a '' in the code. It should be blank otherwise when you go to url http://127.0.0.1:8000/ it doesn't redirect to views.py in the polls folder.
I hope this helps someone. Thanks
I am extremely new to programming. I searched and found a few similar threads here, though unfortunately the answers in those threads didn't seem to fix my own issue.
Problem
I am working my way through the Django tutorials, and I am on the third tutorial:
https://docs.djangoproject.com/en/1.7/intro/tutorial03/
I'm not sure if this matters, but I am working on a Macintosh w/ Mavericks.
The root directory in which I am working is 'Test2'. The directory structure is:
/Users/me/src/collact/collact/test2/
Within 'test2', and per the previous two tutorials, I have '/polls' and '/templates' folders.
My polls/views.py file has the following text:
from django.http import HttpResponse
def index(request):
return HttpResponse("Hello, world. You're at the polls index.")
My polls/urls.py file has the following text:
from django.conf.urls import patterns, url
from polls import views
urlpatterns = patterns('',
url(r'^$', views.index, name='index'),
)
Finally, in /test2/, I have a urls python file as well (.py). It has the text:
from django.conf.urls import patterns, include, url
from django.contrib import admin
urlpatterns = patterns('',
url(r'^polls/', include('polls.urls')),
url(r'^admin/', include(admin.site.urls)),
)
As far as I can tell, this is what the tutorial prescribes. Unfortunately, when I run the server using: python manage.py runserver, the website gives me an error/404 message:
Page not found (404)
Request Method:
GET Request
URL: http://localhost:8000/polls/ Using the URLconf defined in
test2.urls, Django tried these URL patterns, in this order: ^admin/
The current URL, polls/, didn't match any of these. You're seeing this
error because you have DEBUG = True in your Django settings file.
Change that to False, and Django will display a standard 404 page.
Does anyone have any idea how I can fix this? I know that this is a really stupid question, but I have been trying to figure it out for the past day or two, and unfortunately I'm just not familiar enough with programming to solve this on my own.
