Django URL Redirect
Question:
How can I redirect traffic that doesn’t match any of my other URLs back to the home page?
urls.py:
urlpatterns = patterns('',
url(r'^$', 'macmonster.views.home'),
#url(r'^macmon_home$', 'macmonster.views.home'),
url(r'^macmon_output/$', 'macmonster.views.output'),
url(r'^macmon_about/$', 'macmonster.views.about'),
url(r'^.*$', 'macmonster.views.home'),
)
As it stands, the last entry sends all “other” traffic to the home page but I want to redirect via either an HTTP 301 or 302.
Answers:
You can try the Class Based View called RedirectView
from django.views.generic.base import RedirectView
urlpatterns = patterns('',
url(r'^$', 'macmonster.views.home'),
#url(r'^macmon_home$', 'macmonster.views.home'),
url(r'^macmon_output/$', 'macmonster.views.output'),
url(r'^macmon_about/$', 'macmonster.views.about'),
url(r'^.*$', RedirectView.as_view(url='<url_to_home_view>', permanent=False), name='index')
)
Notice how as url in the <url_to_home_view> you need to actually specify the url.
permanent=False will return HTTP 302, while permanent=True will return HTTP 301.
Alternatively you can use django.shortcuts.redirect
Update for Django 2+ versions
With Django 2+, url() is deprecated and replaced by re_path(). Usage is exactly the same as url() with regular expressions. For replacements without the need of regular expression, use path().
from django.urls import re_path
re_path(r'^.*$', RedirectView.as_view(url='<url_to_home_view>', permanent=False), name='index')
If you are stuck on django 1.2 like I am and RedirectView doesn’t exist, another route-centric way to add the redirect mapping is using:
(r'^match_rules/$', 'django.views.generic.simple.redirect_to', {'url': '/new_url'}),
You can also re-route everything on a match. This is useful when changing the folder of an app but wanting to preserve bookmarks:
(r'^match_folder/(?P<path>.*)', 'django.views.generic.simple.redirect_to', {'url': '/new_folder/%(path)s'}),
This is preferable to django.shortcuts.redirect if you are only trying to modify your url routing and do not have access to .htaccess, etc (I’m on Appengine and app.yaml doesn’t allow url redirection at that level like an .htaccess).
Another way of doing it is using HttpResponsePermanentRedirect like so:
In view.py
def url_redirect(request):
return HttpResponsePermanentRedirect("/new_url/")
In the url.py
url(r'^old_url/$', "website.views.url_redirect", name="url-redirect"),
In Django 1.8, this is how I did mine.
from django.views.generic.base import RedirectView
url(r'^$', views.comingSoon, name='homepage'),
# whatever urls you might have in here
# make sure the 'catch-all' url is placed last
url(r'^.*$', RedirectView.as_view(pattern_name='homepage', permanent=False))
Instead of using url, you can use the pattern_name, which is a bit un-DRY, and will ensure you change your url, you don’t have to change the redirect too.
The other methods work fine, but you can also use the good old django.shortcut.redirect.
The code below was taken from this answer.
In Django 2.x:
from django.shortcuts import redirect
from django.urls import path, include
urlpatterns = [
# this example uses named URL 'hola-home' from app named hola
# for more redirect's usage options: https://docs.djangoproject.com/en/2.1/topics/http/shortcuts/
path('', lambda request: redirect('hola/', permanent=True)),
path('hola/', include('hola.urls')),
]
