未找到任何参数的“password_change”反向。尝试了 1 种模式：['r^password_change/$']

Question

我在我的应用程序中添加了 django.contrib.auth 身份验证视图。现在我无法访问这些视图。我收到了上面标题中提到的错误。我是否必须删除命名空间或将命名空间更改为其他名称？

urls.py：

    from django.contrib.auth import views as auth_views
from django.conf.urls import url,include
from . import views

app_name = 'set_goals'

urlpatterns = [
    url(r'^$',views.index,name='index'),
    url(r'^(?P<pk>[0-9]+)/about/$',views.about,name='about'),
    url(r'^(?P<pk>[0-9]+)/download/$', views.download, name='download'),
    url(r'^login_user/$', views.login_user, name='login_user'),
    url(r'^logout_user/$', views.logout_user, name='logout_user'),
    url(r'^register/$', views.register, name='register'),
    url('r^password_change/$',auth_views.password_change,{'post_change_redirect':'set_goals:password_change_done'},name='password_change')

,
url('r^password_change/done/$',auth_views.password_change_done,name='password_change_done'),
]

base.html：

 {% if user.is_authenticated %}
        <li class="nav-item">
          <a class="nav-link" href="{% url 'set_goals:about' user.id %}">All Goals</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="{% url 'set_goals:password_change' %}">Change Password</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="{% url 'set_goals:logout_user' %}">Logout ({{user.username}})</a>
        </li>
        {% else %}
        <li class="nav-item">
          <a class="nav-link" href="{% url 'set_goals:index' %}">About</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="{% url 'set_goals:login_user' %}">Login</a>
        </li>
                      <li class="nav-item">
          <a class="nav-link" href="{% url 'set_goals:register' %}">SignUp</a>
        </li>
        {% endif %}

这里有什么错误？这里要做的改变是什么？请帮忙。提前致谢！

base.html 中带有 password_change 视图的行显示为错误。

Answer 1

你有一个错字：

 url('r^password_change/$',

r 必须放在单引号之前：

 url(r'^password_change/$',

Answer 2

我认为您的 URL 模式是错误的， 试试这个

urlpatterns = [
    # your other patterns

    url(r'^password_change/$', auth_views.password_change,
        {'post_change_redirect': 'set_goals:password_change_done'},
        name='password_change'),
    url(r'^password_change/done/$',
        auth_views.password_change_done,
        name='password_change_done'),
]
