views.generic.base.RedirectView

class django.views.generic.base.RedirectView

Redirects to a given URL.

The given URL may contain dictionary-style string formatting, which will be interpolated against the parameters captured in the URL. Because keyword interpolation is always done (even if no arguments are passed in), any "%" characters in the URL must be written as "%%" so that Python will convert them to a single percent sign on output.

If the given URL is None, Django will return an HttpResponseGone (410).

Ancestors (MRO)

This view inherits methods and attributes from the following view:

django.views.generic.base.View

Method Flowchart

dispatch()
http_method_not_allowed()
get_redirect_url()

Example views.py:

from django.shortcuts import get_object_or_404
from django.views.generic.base import RedirectView
 
from articles.models import Article
 
class ArticleCounterRedirectView(RedirectView):
 
    permanent = False
    query_string = True
    pattern_name = 'article-detail'
 
    def get_redirect_url(self, *args, **kwargs):
        article = get_object_or_404(Article, pk=kwargs['pk'])
        article.update_counter()
        return super(ArticleCounterRedirectView, self).get_redirect_url(*args, **kwargs)

Example urls.py:

from django.conf.urls import url
from django.views.generic.base import RedirectView
 
from article.views import ArticleCounterRedirectView, ArticleDetail
 
urlpatterns = [
    url(r'^counter/(?P<pk>[0-9]+)/$', ArticleCounterRedirectView.as_view(), name='article-counter'),
    url(r'^details/(?P<pk>[0-9]+)/$', ArticleDetail.as_view(), name='article-detail'),
    url(r'^go-to-django/$', RedirectView.as_view(url='https://djangoproject.com'), name='go-to-django'),
]

Attributes

url: The URL to redirect to, as a string. Or None to raise a 410 (Gone) HTTP error.

pattern_name: The name of the URL pattern to redirect to. Reversing will be done using the same args and kwargs as are passed in for this view.

permanent: Whether the redirect should be permanent. The only difference here is the HTTP status code returned. If True, then the redirect will use status code 301. If False, then the redirect will use status code 302. By default, permanent is False.

Changed in Django 1.9:
The default value of the permanent attribute changed from True to False.

query_string: Whether to pass along the GET query string to the new location. If True, then the query string is appended to the URL. If False, then the query string is discarded. By default, query_string is False.

Methods

get_redirect_url(*args, **kwargs)

Constructs the target URL for redirection.

The default implementation uses url as a starting string and performs expansion of % named parameters in that string using the named groups captured in the URL.

If url is not set, get_redirect_url() tries to reverse the pattern_name using what was captured in the URL (both named and unnamed groups are used).

If requested by query_string, it will also append the query string to the generated URL. Subclasses may implement any behavior they wish, as long as the method returns a redirect-ready URL string.
