python - Django:解析 "Reverse for ' password_reset_complete' 未找到。”

Question

我正在尝试使用自定义 html 模板使用 Django 重置密码。我可以通过电子邮件请求重置密码(使用 EMAIL_BACKEND = 'django.core.mail.backends.console.EmailBackend')，然后我会在控制台中收到一封“电子邮件”，如我所愿。电子邮件确实将我带到了我想要的“password_reset_confirm.html”页面，我可以为与用户关联的用户输入新密码。

但是，当我点击“重设密码!”时出现以下错误。按钮:

"Reverse for 'password_reset_complete' not found. 'password_reset_complete' is not a valid view function or pattern name."

尽管出现此错误，但密码确实发生了变化，但我(显然)不希望出现此错误。

项目的结构在主结构中有一个用户“app”，所以它是:

项目
主应用
用户
----模板
--------注册
--------------password_reset_form.html
-----------password_reset_confirm.html
--------------password_reset_done.html
--------------password_reset_email.html
-----------password_reset_complete.html

我在users中的urls.py代码如下:

from django.urls import path, include, reverse_lazy

from . import views
from django.contrib.auth import views as auth_views

app_name = 'users'
urlpatterns = [
    # Default authorisation urls.
    path('', include('django.contrib.auth.urls')),
    # Registration page.
    path('register/', views.register, name='register'),
    # Password reset urls.
    path(
        'password_reset',
        auth_views.PasswordResetView.as_view(
            template_name='registration/password_reset_form.html',
            email_template_name='registration/password_reset_email.html',
            success_url=reverse_lazy('users:password_reset_done')
        ),
        name='password_reset'
    ),
    path(
        'password_reset/done/',
        auth_views.PasswordResetDoneView.as_view(template_name='registration/password_reset_done.html'),
        name='password_reset_done'
    ),
    path(
        'reset/<uidb64>/<token>/',
        auth_views.PasswordResetConfirmView.as_view(
            template_name='registration/password_reset_confirm.html',
            success_url=reverse_lazy('users:password_reset_complete.html')
        ),
        name='password_reset_confirm'
    ),
    path(
        'reset/done/',
        auth_views.PasswordResetCompleteView.as_view(template_name='registration/password_reset_complete.html'),
        name='password_reset_complete'
    ),

]

我有一个类似的问题，但有“password_reset_done”，但是我能够通过查看这个网站来解决这个问题，通过添加

success_url=reverse_lazy('users:password_reset_done')

到密码重置的路径，这解决了那个问题，但是我随后遇到了上面的后续问题，而且我还没有找到任何解决它的解决方案。将以下内容添加到 password_reset_confirmation 的路径没有帮助:

success_url=reverse_lazy('users:password_reset_complete.html')

例如，我尝试将其更改为登录页面，但似乎没有任何变化，经调查发现我可以删除以下内容，程序将保持不变:

    path(
        'reset/<uidb64>/<token>/',
        auth_views.PasswordResetConfirmView.as_view(
            template_name='registration/password_reset_confirm.html',
            success_url=reverse_lazy('users:password_reset_complete.html')
        ),
        name='password_reset_confirm'
    ),
    path(
        'reset/done/',
        auth_views.PasswordResetCompleteView.as_view(template_name='registration/password_reset_complete.html'),
        name='password_reset_complete'
    ),

这就是为什么本例中的 success_url 没有改变行为。我想知道 password_reset_email.html 是否是罪魁祸首，以防这导致调用“password_reset_confirm”，而不是“user:password_reset_confirm”(因为 urlpattern 被忽略)。

password_reset_email.html:

{% autoescape off %}
To initiate the password reset process for your account, click the link below:

{{ protocol }}://{{ domain }}{% url 'users:password_reset_confirm' uidb64=uid token=token %}
If clicking the link above doesn't, please copy and paste it into a new browser instead.

{% endautoescape %}

我还包含了 password_reset_confirm.html 代码，以防有帮助:

{% extends "demeter_app/base.html" %}

{% block content %}
    <p>Please enter your new password:</p>
    <form method="post">
        {% csrf_token %}
        {{ form.as_p }}
        <input type="submit" value="Reset password!">
    </form>
{% endblock content %}

有人知道我该如何解决这个问题吗？我试过查看 Stackoverflow，但大多数查询都与 password_reset_done 相关，而不是 password_reset_complete。

它对您不起作用，因为链接顺序已损坏。首先，重新指定的应该去，然后才是标准的。为了正常操作，这样做就足够了:

urlpatterns = [
    path('password_reset/',
        auth_views.PasswordResetView.as_view(
            success_url=reverse_lazy('users:password_reset_done')), 
        name='password_reset'),
    path('reset/<uidb64>/<token>/', 
        auth_views.PasswordResetConfirmView.as_view(
            success_url=reverse_lazy('users:password_reset_complete')), 
        name='password_reset_confirm'),
    path('', include('django.contrib.auth.urls')),
]

这个顺序是必要的，因为'django.contrib.auth.urls'已经包含'reset/ / /' 。因此，您的代码没有运行。
