【问题描述】：

我正在尝试创建一个用于通过电子邮件重置忘记密码的系统，但遇到了一些错误。

我的网址是：

from django.contrib.auth import views as auth_views

urlpatterns = [
    url(r'^$', auth_views.login, name='login'),
    url(r'^logout/$', auth_views.logout, name='logout'),
    ## more irrelevant urls here ##
    url(r'^password/reset/done/$', auth_views.PasswordResetDoneView.as_view(), name='password_reset_done'),
    url(r'^password/reset/$', auth_views.PasswordResetView.as_view(), name='password_reset'),
    url(r'^password/reset/(?P<uidb64>[0-9A-Za-z_\-]+)/(?P<token>[0-9A-Za-z]1,13-[0-9A-Za-z]1,20)/$', auth_views.PasswordResetConfirmView.as_view(), name='password_reset_confirm'),
    url(r'^password/reset/complete/$', auth_views.PasswordResetCompleteView.as_view(), name='password_reset_complete'),
]

在password_reset 提交电子邮件地址时，电子邮件发送但我收到此错误：

当我将链接复制到浏览器并重置密码时，密码重置正确但出现以下错误：

技术上是系统功能，但显然这些错误信息并不理想。

以下是我对此提出的其他问题：

NoReverseMatch error with password reset emails

Error with system for email password resets

这就是我关注的tutorial。

【问题讨论】：

也许你的应用中有这个 url 文件？

@LeLouch 是的，它在一个名为选举的应用程序中。不应该吗？

您链接到的教程不使用基于类的视图..？还注意到 /password/reset/MQ/set-password/ 与您的 password_reset_confirm 网址匹配...

@thebjorn 在切换到基于类的视图之前，我遇到了 NoReverseMatch 错误。我相当肯定使用这些视图的基于类的版本不是这些错误的原因。另外，网址不应该匹配吗？

好吧，因为我看不到你的文件结构和完整的 url，所以在你的主 url 文件中包含这个 url 应该可以解决你的问题

【参考方案1】：

您没有得到反向匹配，因为 password_reset 函数重定向到 ('password_reset_done') 而不是您的应用命名空间 有关详细信息，您可以查看here 中的文档

例如，如果您的选举应用程序的包含 url 看起来像这样：

urlpatterns = [
    url(r'election', include(election.urls, namespace="SomeName")),

]

您可以通过删除包含 url 中的名称/命名空间来解决问题，或者您需要覆盖 password_reset 函数。 从 django.contrib.auth.view 导入密码重置

#views.py
def new_password_reset(password_reset):
    if post_reset_redirect is None:
        post_reset_redirect = reverse('SomeName:password_reset_done')

    return TemplateResponse(request, template_name, context) 

#urls.py
from election import views as election_views
#and in your urls change that url:
url(r'^password_reset/$', auth_views.password_reset, name='password_reset')

#with that url :
url(r'^password_reset/$', election_views.new_password_reset, name='password_reset')

你应该没事的

【参考方案2】：

我不知道这在较新的 Django 中是否仍然可行，但在以前的版本中我们已经这样做了：

# django login views
urlpatterns += patterns(
    'django.contrib.auth.views',
    url(r'^logout/$',
        'logout',
        dict(
            template_name='my/logout.html',
            redirect_field_name='next',
        )),

    url(r'^password-reset/$',
        'password_reset',
        dict(
            template_name='my/password-reset-form.html',
            email_template_name='my/password-reset-email.html',
            subject_template_name='my/password-reset-email-subject.html',
            from_email=settings.FROM_EPOST,
        ),
        name="my-password-reset"),

    url(r'^password-reset-done/$',
        'password_reset_done',
        dict(
            template_name='my/password-reset-done.html',
        )),

    url(r'^password-reset-confirm/(?P<uidb64>.+)/(?P<token>.+)/$',
        'password_reset_confirm',
        dict(
            template_name='my/password-reset-confirm.html',
            # post_reset_redirect='url',
        )),

    url(r'^password-reset-complete/$',
        'password_reset_complete',
        dict(
            template_name='my/password-reset-complete.html',
        )),
)

我似乎记得在这些网址中有斜杠是个问题，但我已经很久没有写这些了..

电子邮件模板包含：

% block reset_link %
 protocol :// domain % url 'django.contrib.auth.views.password_reset_confirm' uidb64=uid token=token %
% endblock %
