In Django, we define url mapping in urls.py. Whats the difference between these two?
/app/kill/$
/app/kill$
They are both very different urls. But for must users they will be expected to be the same so django has a nice feature for this: the APPEND_SLASH settings variable.
From the docs:
When set to True, if the request URL does not match any of the patterns in the URLconf and it doesn't end in a slash, an HTTP redirect is issued to the same URL with a slash appended.

In my application , I need to display the REST url(s) without a slash at the end. I have tried below combination but it didnt work.
Added APPEND_SLASH=True in the settings.py
and on the urls.py file
from rest_framework.routers import SimpleRouter
router = SimpleRouter(trailing_slash=False)
After adding this when I am calling the urls without slash at the end in the postman, it is giving me an 404 error- URL not found. But with slash at the end is working fine.
Is there any option to make this url without with slash at the end ? Especially for the post urls
APPEND_SLASH will append it to the request (e.g. mysite/blog --> mysite/blog/). This is not what you want, since your urlconf explicitly says there should be no slash.
Also APPEND_SLASH is True by default. So you need to set it to False instead. That way, if you make a request without a slash, Django won't automatically add in a slash.
I am using Django 1.10, and my goal now is to make urls available both with and without trailing slash. To do this, I added slash to all my URLs in the URLConf files, and then set APPEND_SLASH variable value to True (well, this is the default value).
Now the problem is that external POST requests (which I can't control) yield the following error:
You called this URL via POST, but the URL doesn't end in a slash and
you have APPEND_SLASH set. Django can't redirect to the slash URL
while maintaining POST data. Change your form to point to
127.0.0.1:8000/Calendar/AddAccounts/ (note the trailing slash), or set APPEND_SLASH=False in your Django settings.
They mention this in Django doc, and yet after hours of surfing the net, I can't figure out how to address this issue.
I've also come across this question, but the proposed solution doesn't seem acceptable to me. It says I have to make the users call my URLs only with trailing slash. While I know that in other languages (C# for example) it is possible to enable both options
It seems weird to me that you want to support both cases. Ideally you would want to redirect from non slash to slash(or the other way around if you want that) on the server level (nginx/apache/whatever you use) before the request hits Django.
Just choose a strategy and stick to it, so add the trailing slash to your form and never look back. :)
It's important to be consistent. https://www.branded3.com/blog/urls-trailing-slash-seo/
If the urls are used for APIs or the SEO is not important to you, you can consider both with slash and without slash by adding "/?". In django 3.X:
from django.urls import re_path
re_path(r'^query/?$', 'search.views.query'),
re_path(r'^add/?$', 'search.views.add'),
In Restframework routers:
from rest_framework.routers import DefaultRouter
class CustomDefaultRouter(DefaultRouter):
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
self.trailing_slash = '/?'
router = CustomDefaultRouter()
router.register('link', ViewSet, basename='link')
I am using django social auth in my app and I found a Page not found error.
I have installed it in my app and also place it in my project parallel to my app.
And I have also add url to my url file
url(r'', include('social_auth.urls')),
But when it shows me the error It shows the list of url in my url file and where i have the required url which i am looking for.
The error page is as :
Page not found (404)
Request Method: GET
Request URL: http://abc.com/login/
Using the URLconf defined in webdev.urls, Django tried these URL patterns, in this order:
^$ [name='home']
^polls/
^admin/doc/
^admin/
^register1/
^edit/
^edit1/
^customerreg/
^checkout/
^checkout1/
^order/
^order1/
^upload/
^upload1/
^product/
^profile/
^logout/
^login/(?P<backend>[^/]+)/$ [name='socialauth_begin']
^complete/(?P<backend>[^/]+)/$ [name='socialauth_complete']
^associate/(?P<backend>[^/]+)/$ [name='socialauth_associate_begin']
^associate/complete/(?P<backend>[^/]+)/$ [name='socialauth_associate_complete']
^disconnect/(?P<backend>[^/]+)/$ [name='socialauth_disconnect']
^disconnect/(?P<backend>[^/]+)/(?P<association_id>[^/]+)/$ [name='socialauth_disconnect_individual']
The current URL, login/, didn't match any of these.
In the above list you can see that url file have that url , but it doesn't access that ??
^login/(?P<backend>[^/]+)/$ [name='socialauth_begin']
This url do not match with http://abc.com/login/ as the url pattern requires a backend parameter.
Something like this will match the url you are accessing, however there is no backend parameter there, so in view you may want to choose something default.
url(r'^login/$', 'your_view',),
i am trying to define a url pattern in django urls.py like
url(r'^networking$','mysite1.networking.views.networking'),
when i am typing http://myhost.com/networking in my address bar to go to networking page
i am getting 404 error and a slash '/' automatically added to the address bar like
http://myhost.com/networking/
help me out what i am doing wrong?
You probably aren't including your urlconf correctly. The behavior you're seeing is because of APPEND_SLASH is set to True by default when Django can't resolve the url.
Either set Append_Slash to false which is true by default or use your url description like given below which redirect url with slash to desired view.
url(r'^networking/$','mysite1.networking.views.networking'),
Seems your Apache server or some Django middleware is adding trailing slashes. You can either correct that, or the better way is you can use the following url pattern:
url(r'^networking/?$','mysite1.networking.views.networking'),
I've made a simple site in Django. The urls I use are http::/www.example.com/nl/ and http://www.example.com/fr/.
My Django urls.py has the following line:
(r'^(?Pnl|fr)/', 'example.views.index'),
In example.views.index I check the language parameter. If it's 'nl' I show a template. If it's 'fr', I show a different template.
This worked great. Now the customer made two different urls:
http://www.dutch.com/ and http://www.french.com/
And finally I'll ask the question:
Is there a way for me to use the new urls without changing my django code? I assume I can tell apache to present the http://www.example.com/nl/ page when the user goes to http://www.dutch.com/. But how do I do this? And will django still be able to get the 'language' parameter from the url?
Thanks in advance for any answers.
If you can use .htaccess files on http://www.dutch.com that you can use apache's redirect directive like so
redirectMatch 301 ^(.*)$ http://www.example.com/nl/
This will redirect all requests sent to dutch.com to example.com/nl
You could also use
redirect 301 /index.html http://www.example.com/nl/
This will redirect only "index.html" on dutch.com to example.com/nl/ (note that the first parameter is a path and can't be an URL - no http://www)
