从 django 中的 views.py 重定向到另一个 url 时发生 NoReverseMatch 错误

Question

我正在尝试在注册完成后重定向用户并收到以下错误。

Reverse for 'verificationsent' with arguments '()' and keyword arguments '{}' not found. 0 pattern(s) tried: []

urls.py --

urlpatterns = [
    url(r'^ciasadmin/', admin.site.urls),
    url("^$", views.homepage, name="home"),
    url(r'^account/', include('accounts.urls')),
]

accounts/urls.py --

from django.conf.urls import url
from . import views


urlpatterns = [
    url(r"^signup/$", views.signup, name="account_signup"),
    url(r'^verificationsent/$', views.verificationsent, name='account_verificationsent'),
    url(r'^activate/(?P<uidb64>[0-9A-Za-z_\-]+)/(?P<token>[0-9A-Za-z]{1,13}-[0-9A-Za-z]{1,20})/$',views.activate, name='activate'),
]

views.py --

return redirect('verificationsent')

完整的追溯

我已遵循以下 SO 参考中的解决方案，但没有奏效。

Redirect with parameters. NoReverseMatch at /test/

Django NoReverseMatch in form redirect

非常感谢任何帮助。提前致谢。

根据最佳实践，您不应使用直接 url 引用语句。总是reverse 网址

return redirect(reverse('account_verificationsent'))

如果您的应用程序有一个命名空间，那么您也必须反过来使用它。
