How to solve "Page not found (404)" error in Django?

Question

My project is named homefood, and when I runserver I get this error.Anybody have any clue how to fix this error.

Page not found (404)

Request Method: GET

Request URL:    http://127.0.0.1:8000/

Using the URLconf defined in homefood.urls, Django tried these URL patterns, in this order:

^foodPosts/

^admin/

The current URL, , 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.

My settings.py file looks like this...

import dj_database_url
"""
Django settings for homefood project.

BASE_DIR = os.path.dirname(os.path.dirname(__file__))

and my urls.py in my homefood folder is

from django.conf.urls import patterns, include, url

from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    # Examples:
    # url(r'^$', 'homefood.views.home', name='home'),
    # url(r'^blog/', include('blog.urls')),

    url(r'^foodPosts/',include('foodPosts.urls')),
    url(r'^admin/', include(admin.site.urls)),
)

I think my problem is either in my urls.py, or my settings.py but I am unsure. Any help would be greatly appreciated. Thanks.

Answer 1

You are getting the 404 because you haven't defined a url pattern for http://127.0.0.1:8000/ yet.

You should be able to view the admin site at http://127.0.0.1:8000/admin/ and your food posts at http://127.0.0.1:8000/foodPosts/.

To add a url pattern for the homepage, uncomment the following entry in your urls.py, and replace homefood.views.home with the path to the view you want to use.

url(r'^$', 'homefood.views.home', name='home'),

Basically the answer to this to add a entry in the project urls.py file as blank example:

path('', include('MYAPP.urls')),

and in the app urls.py you add this

url('MYAPP', views.index),

make sure in the settings.py you include your app also make sure in the app urls.py you import your views

Thank you for help. I can see the page now but only by adding path('', include('MYAPP.urls')), in project's urls.py. I didn't understand why it need to add second line in app's urls.py and also couldn't understand the reason of adding app in settings.py Sorry if you find this question very basic as I'm a newbie in Django. If you can elaborate then would be really helpful – Arabist

Answer 3

I had this error too and the solution was to change double quotes to single quotes for the name= parameter in the urls.py file of the concerned app!

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

Thanks for this - I don't know how long I would have been searching for this... otherwise – Flapdoodle

Answer 4

Not directly relevant to the OP, but maybe useful for others:

My admin pages all went 404 after I accidentally removed the trailing slash from the path() route (django 3.2):

urlpatterns = [
    path('admin', admin.site.urls),  # trailing slash missing...
    path('', include('myapp.urls'))
]

This was easily fixed by restoring to 'admin/'.

It's work for me by just added / in the end of 'users' in urls.py app file look like this

path('users/', get_users, name='users')

Answer 6

I got the same error below:

Page not found (404)

Because I didn't put / after test/<int:id> as shown below:

urlpatterns = [     # ↓ Here
    path('test/<int:id>', views.test, name="test")
]

So, I put / after test/<int:id> as shown below, then the error was solved:

urlpatterns = [      # ↓ Here
    path('test/<int:id>/', views.test, name="test")
]

Answer 7

You only see the landing page when there are NO URLS defined:

As soon as you configure a URL (e.g foodPosts/) , the / route will NOT show the landing page unless you explicitly define a / route in urls.py

Hence you don't see that rocket with this link : http://127.0.0.1:8000/
