I'm developing my first app in Django and facing some issues. The server runs smoothly and I can operate the admin panel without any issues.
However, all of the app pages including the default homepage show a "404 not found" error.
I have created a templates directory in project root
updated this line in settings.py for templates,
'DIRS': [os.path.join(BASE_DIR,'templates')],
View for the app
from django.shortcuts import render
from .models import *
# Create your views here.
def customers(request):
customers = Customer.objects.all()
return render(request, "customers.html", {'customers': customers})
urls for the app
from django.urls import path from . import views
urlpatterns = [path('customers',views.customers, name='customers')]
urls for the project
from django.contrib import admin from django.urls import path, include from django.conf import settings from django.conf.urls.static import static
urlpatterns = [
path('trips/',include('trips.urls')),
path('customers/',include('customers.urls')),
path('drivers/',include('drivers.urls')),
path('vehicles/',include('vehicles.urls')),
path('admin/', admin.site.urls), ]
urlpatterns = urlpatterns + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
Help is appreciated
I can't see any problem with your case, you should be able to load http://localhost:8000/customers/customers. Maybe double customers was not you intention, then remove one of them (one in main urls.py one in app's).
Also when Django debug mode is active and you get a 404 because of URL mismatch, it shows you a list of URLs you have. To see it navigate to a non existing URL like http://localhost:8000/aaa. Then if you see customers/ there try http://localhost:8000/customers/. Go step by step to find the problem.

I am starting my first django application. I constantly keep getting 404 error after turning on server locally in my computer. I don't see any reason for such return because urls seem to be correct when compared to tutorials and guides on the internet.
This is my urls file inside app (app name is reservations)
from django.urls import path
from . import views
urlpatterns = [
path('', views.index, name='index')
]
This is urls file in project folder (project name is website)
from django.contrib import admin
from django.urls import include, path
urlpatterns = [
path('admin/', admin.site.urls),
path('reservations/', include('reservations.urls'))
]
and this is index function which is supposed to show basic html
def index(request):
response = """<html><body><p>This is home page</p></body></html>"""
return HttpResponse(response)
I thought that my urls are written incorrectly so i tried writing them in different way but it never worked. Thanks for any help.
I am trying to import views from my apps into the urls.py file. For awhile, I was able to using "from app_name.views import view_name", but for some reason now it is not recognizing the app name.
I did not change anything in my settings.py file so I'm not sure what caused this. I did delete some migrations and an my database.
One thing that is weird is that I can import them if I go up a folder so, "from src.appname.views" and this seems to work, but is not what I want since by base directory is the src folder.
from django.contrib import admin
from django.urls import path
from pages.views import home_page, history, more_information, prop_analysis
from Product.views import property_analysis_tools, property_analysis_results
urlpatterns = [
path('admin/', admin.site.urls),
path('', home_page),
path('home', home_page),
path('history', history),
path('information', more_information),
path('analyze', prop_analysis),
path('results', property_analysis_results)
Another odd thing is that when I run the server, all of these views seem to work. Can Django sometimes give off false errors?
In Django in order to import an app.view into project urls, we create an additional urls.py in every app and link that urls.py into
our project urls.py , just as shown below
change project urls.py
from django.contrib import admin
from django.urls import path, include
urlpatterns = [
path('admin/', admin.site.urls),
path('', include('pages.urls', namespace="pages")),
]
create another urls.py in your pages app
as below, similarly in any other apps.
from django.urls import path
from .views import (home_page,history,....)
app_name = 'pages'
urlpatterns = [
path(' ', homepage , name='homepage-view'),
path('history/',history, name='history-view'),
]
Every other view from respective app.views will be included in corresponding app.urls [if u have multiple apps]
nB: changes may occur according to your settings.py configurations,
for more, read this django URL documentation
watch Corey Schafer playlist best Django tutorial for beginners
I started working on django ( read the django documentation and several youtube tutorials )
I dont understand what is wrong , the editor is not showing any errors ( VSCode ).
When I start the server it is showing me the default rocket icon ....I have tried reinstalling django but it also didnt help....also restarted the server several times.
I am stuck right now.
main url file
from django.contrib import admin
from django.urls import path, include
urlpatterns = [
path('calc/',include('calc.urls')),
path('admin/', admin.site.urls),
]
url file for the app (calc)
from django.urls import path
from . import views
urlpatterns = [
path('',views.index,name='index')
]
views file for the app
from django.shortcuts import render
from django.http import HttpResponse
# Create your views here.
def home(request):
return HttpResponse("Hello World")
edit url path in calc app to the below.
path('', views.home ,name='index')
I am a beginner in Django I have created a Django project in that I have included two more application when I did add urls.py file in both Applications both are working well but when I am fetching my main admin URL it is giving an error
Page not found (404)
Request Method: GET
URL: http://127.0.0.1:8000/
the URLconf defined in mac.urls, Django tried these URL patterns, in this order:
admin/
shop/
blog/
The empty path 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.
when I am fetching this URL in http://127.0.0.1:8000/ i am getting an error it is working for http://127.0.0.1:8000/shop/
here is my main urls.py
from django.contrib import admin
from django.urls import path, include
urlpatterns = [
path('admin/', admin.site.urls),
path('shop/', include('shop.urls')),
path('blog/', include('blog.urls')),
]
Your django app has 3 routes:
http://127.0.0.1:8000/admin/ goes to django admin app
http://127.0.0.1:8000/shop/ goes to your shop app
http://127.0.0.1:8000/blog/ goes to your blog app
And since you have no configuration for http://127.0.0.1:8000, you see an error instead.
You can see that in the error, when django tries to match your url with list of available urls.
If you want to get admin app on url http://127.0.0.1:8000, change urls.py to:
from django.contrib import admin
from django.urls import path, include
urlpatterns = [
path('', admin.site.urls),
path('shop/', include('shop.urls')),
path('blog/', include('blog.urls')),
]
It's generally not advisable to set admin app at root url - it has it's own system of urls inside (admin/<app_name>/<model_name>), so chances are it will shadow your urls and make the unreachable.
Create a view that will be your front page.
From there you should link to the other areas of your website.
Don't direct that to admin, that's ridiculous.
You've created a Django project and started two apps. You should have a project-level urls.py file and then an app-level urls.py file for each of your apps.
To explain that in greater detail lets say our Django project is called config and our two apps are called app1 and app2. Your project-level urls.py file, which will be located at config/urls.py, could contain the following:
# config/urls.py
from django.contrib import admin
from django.urls import path, include
from django.views.generic.base import TemplateView
urlpatterns = [
path('admin/', admin.site.urls),
path('', TemplateView.as_view(template_name='home.html'),
name='home'),
path('app1/', include('app1.urls')),
path('app2/', include('app2.urls')),
]
In this file we specify a route for our admin panel, which on your local server will be located at http://127.0.0.1:8000/admin. We've also specified a home route, the second path with the empty string. This means when you navigate to http://127.0.0.1:8000/ you will be directed to your home page (for the example above I just used a generic built-in view). It's not a good idea to route immediately to your admin panel.
We've also included paths to our other two apps. What these two lines essentially say is: "include the urls from this other app". Now we need to create two urls.py files, one for each of our apps. In this example I'll just focus on the urls.py file for app1:
# app1/urls.py
from django.urls import path
from .views import AppContentView
urlpatterns = [
path('content/', AppContentView.as_view(),
name='app_content'),
]
This is a view that you would have to create, but what we've now done is we've created one path that will be located at http://127.0.0.1:8000/app1/content. In fact any new paths we create in this file will always begin with http://127.0.0.1:8000/app1/, because we've already told Django in our project-level urls.py to include the urls from the app1 urls.py file so we've essentially prefixed all of these paths with /app1/.
If you think of urls configurations like a tree it might help too:

I have a working api, and I am writing a UI to the API, as a separate application in the same project. My project urls.py looks like this
from django.conf.urls import *
import search
from django.contrib import admin
admin.autodiscover()
urlpatterns = patterns('',
url(r'^api/search$', search.validation),
url(r'^ui', include('ui.urls')),
)
My UI app's urls.py looks like this
from django.conf.urls import *
import views
urlpatterns = patterns('',
(r'^ui/$', views.search_template),
)
However, when I am trying to access with my browser(domain.com:8000/ui), I am getting an error.
Using the URLconf defined in api.urls, Django tried these URL patterns, in this order:
^api/search$
^ui ^ui$
The current URL, ui, didn't match any of these.
But if I use the below mapping in the main project's urls.py, it works.
(r'^ui$', ui.views.user_template),
I tried clearing the urls.pyc to make sure it is not stale, but it still persists. Please let me know what am I doing wrong.
You shouldn't repeat ui regex in the app's urls.py:
urlpatterns = patterns('',
(r'^$', views.search_template),
)
