我看了很多关于stackoverflow的讨论，但没有一个有帮助。所以我决定在这里粘贴我的代码。所以请帮我找出我做错的地方。谢谢

这是 urls.py

(r'^showusersignin/(?P<userid>\d+)/$', 'views.showusersignin'),

这是views.py中的定义

def showusersignin(request,userid):

这是signin.html

{%for rec in records.object_list%}

        <tr>
            <td width = "15%">
               <a href="{%url views.showusersignin userid='rec.0' %}">{{rec.0}}</a>
            </td>
            <td width = "15%">
                {{rec.1}}
            </td>
            <td width = "15%">
                {{rec.2}}
            </td>

        </tr>
 {%endfor%}

服务器上的错误

你做错了两件事。

首先，你把'rec.0'字符串作为字符串放入 url 标记中。我认为您的意思是传递该列表项的值，所以您应该这样做userid=rec.0

其次，您的 URL 没有userid参数，因为您没有使用命名参数。将其更改为r'^showusersignin/(?P<user_id>\d+)/$'，或将您的 url 标签更改为{%url views.showusersignin rec.0 %}
