python - 在 View 中找不到 Django Reverse，但 URL 有效

Question

我有一个包含一些应用程序的项目，例如帐户、Webadmin、等

登录后，我将用户重定向到Webadmin的 View 。 问题是我可以通过浏览器查看 Webadmin 页面!这意味着链接有效。

但是每当我尝试重定向查看时，它都会出现此错误。这是回溯

Environment:


Request Method: POST

这是我来自网站应用程序(根应用程序)的 urls.py 代码

from django.conf.urls import patterns, include, url
from django.contrib import admin
from django.conf.urls.static import static
from django.conf import settings

urlpatterns = patterns(
'',
url(r'^$', 'website.views.home', name='home'),
url(r'^account/', include('account.urls', namespace='account')),
url(r'^admin/', include('webadmin.urls', namespace='webadmin')),
url(r'^admin-panel/', include(admin.site.urls)),
)
if settings.DEBUG:
    import debug_toolbar
    urlpatterns += patterns('',
    url(r'^__debug__/', include(debug_toolbar.urls)),
    ) + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

来自 webadmin 应用程序的 url.py 代码

from django.conf.urls import patterns, url
urlpatterns = patterns('',
    url(r'create/$', 'webadmin.views.create', name='create'),
    url(r'list/$', 'webadmin.views.list_sites', name='list_sites'),
)

来自帐户应用程序的url.py代码

from django.conf.urls import patterns, url


urlpatterns = patterns( '',
    url(r'^view/(?P<id>\d+)/$', 'account.views.view', name='profile'),
    url(r'^login/$', 'account.views.sign_in', name='sign_in'),
    url(r'^register/$', 'account.views.sign_up', name='sign_up'),
    url(r'^logout/$', 'account.views.signout', name='logout'),
    url(r'^edit/$', 'account.views.edit', name='edit'),
    url(r'^activate/(?P<token>\d{4})/$', 'account.views.activate', name='activate'),
)

我用这个小代码重定向到list_sites(与其他应用程序的其他 View 一起使用)

from django.shortcuts import redirect
from webadmin.views import list_sites as webadmin_home

def someview(request):
    return redirect(webadmin_home)

我错过了什么吗？为什么会出现这个错误？如何修复它？ 提前致谢

Answer 1

您不会重定向到 View 方法，而是重定向到 URL。在 urls.py 中，您已经为该 URL 指定了一个名称，因此您需要使用该名称。

return redirect('webadmin:create')
