位于/password_reset_complete/‘NoReverseMatch’的用户不是已注册的命名空间

Question

基础urls.py：

from django.contrib import admin
from django.urls import path, include
from django.contrib.auth import views as auth_views
from users import views as user_views

urlpatterns = [
    path('admin/', admin.site.urls),
    path('register/', user_views.register , name='register'),
    path('login/', auth_views.LoginView.as_view(template_name='users/login.html'), name='login'),
    path('logout/', auth_views.LogoutView.as_view(template_name='users/logged_out.html'), name='logout'),
    path('password_reset/',
         auth_views.PasswordResetView.as_view(template_name='users/password_reset.html'),
         name='password_reset'),
    path('password_reset/done/',
         auth_views.PasswordResetDoneView.as_view(template_name='users/password_reset_done.html'),
         name='password_reset_done'),
    path('password_reset_confirm/<uidb64>/<token>/',
         auth_views.PasswordResetConfirmView.as_view(template_name='users/password_reset_confirm.html'),
         name='password_reset_confirm'),
    path('password_reset_complete/',
         auth_views.PasswordResetCompleteView.as_view(template_name='users/password_reset_complete.html'),
         name='password_reset_complete'),
    path('', include('learning_logs.urls')),
]

password_reset_confirm.html：

{% extends "learning_logs/base.html" %}
{% load bootstrap4 %}

{% block page_header %}
    <h2>Reset your password.</h2>
{% endblock page_header %}

{% block content %}
    <form method="post">
    {% csrf_token %}
    {%  bootstrap_form form %}
    <button type="submit" class="btn btn-primary">Submit</button>
  </form>

{% endblock content %}

password_reset_complete.html：

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

{% block content %}
    <p>Password changed </p>
    <a href="{% url 'login' %}">Sign in</a>
{% endblock content %}

我试图找到这个错误所指的命名空间'users‘的引用。但我不知道来源在哪里。每当我填写用于重置密码的password_reset_confirm字段时，都会出现此错误。有什么想法吗？

回溯：

    extra, resolver = resolver.namespace_dict[ns]

During handling of the above exception, another exception occurred:

Answer 1

这个解决方案通常在这里可能会有帮助！最好在settings.TEMPLATES中定义模板目录DIRS列表

其中一种常见的方法是在每个应用程序中都有一个，层次结构如下：

testproject/
    testproject/
        settings.py
        urls.py
        ....
    users/
        models.py
        views.py
        ....
        templates/
            users/
                password_reset.html
                ....
    manage.py
    ....

然后，在settings.py上明确提到模板DIRs

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [
            'users/templates'
        ],
        ....
    }
]

这将避免Django混淆。现在，您可以像上面提到的那样添加template_name：template_name='users/password_reset.html'

Answer 2

在settings.py中我有：LOGIN_URL = 'users:login，它应该是LOGIN_URL = 'login'
