我向我的应用程序添加了django.contrib.auth身份验证视图。现在，我无法访问这些视图。我收到上面标题中提到的错误。我是否必须删除名称空间或将名称空间更改为其他名称？urls.py：    from django.contrib.auth import views as auth_viewsfrom django.conf.urls import url,includefrom . import viewsapp_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 %}这是什么错误？在这里要做什么更改？请帮忙。提前致谢！错误的StackTrace：    NoReverseMatch at /Reverse for 'password_change' with no arguments not found. 1 pattern(s) tried: ['r^password_change/$']Request Method: GETRequest URL:    http://127.0.0.1:8000/Django Version: 2.0.7Exception Type: NoReverseMatchException Value:    

Answer 1

您有错别字：

 url('r^password_change/$',

在[R必须放在单引号之前：

 url(r'^password_change/$',

Answer 2

您的网址格式有误，我认为，请尝试此操作

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'),

]
