views.py

Question

很抱歉，如果它是noob代码或问题。我正在使用django-pagination进行分页，我正在这样做。但是这在我的页面上给了我keyError，它还提到它在模板渲染过程中出错。我在这里做错了。我已经成功安装了分页，修改了settings.py文件。但我不知道我需要做什么。任何帮助将受到高度赞赏。

 <table class="active_table"  summary="active_user">
    <thead>
     <tr><th>Name</th><th>Mobile Number</th><th>Count</th></tr>
    </thead>
    <tbody id="table_content">
     {% load pagination_tags %}
       {% block content %}
         {% autopaginate response_data 5 %}
           {% for b in response_data %}
              <tr class="table_rows"><td>{{ b.name }}</td><td>{{ b.mobile_number }}</td><td>{{ b.count }}</td></tr>
           {% endfor %}
         {% paginate %}
        {% endblock %}
     </tbody>
  </table>

视图代码如下

views.py

@csrf_exempt

def active_user_table（request，b）： if request.method！=“GET”：提高Http404

if (b=='4'):
         cursor = connection.cursor()
         cursor.execute("SELECT core_user.id, name,mobile_number,COUNT(*) as count, created FROM core_user,core_useractivity WHERE core_user.id = core_useractivity.user_id GROUP BY user_id ORDER BY count DESC")
         response_data = dictfetchall(cursor)
         return render_to_response("siteadmin/active_user_table.tmpl",{'response_data':response_data})
elif (b=='3'):
         cursor = connection.cursor()
         cursor.execute("SELECT core_user.id, name, mobile_number, COUNT(*) as count, created FROM core_user, core_useractivity WHERE core_user.id = core_useractivity.user_id AND MONTH(CAST(created as date)) = MONTH(NOW()) AND YEAR(cast(created as date)) = YEAR(NOW()) GROUP BY user_id ORDER BY count DESC")
         response_data = dictfetchall(cursor)
         return render_to_response("siteadmin/active_user_table.tmpl",{'response_data': response_data})
elif (b=='2'):
         cursor = connection.cursor()
         cursor.execute("SELECT core_user.id, name, mobile_number, COUNT(*) as count, created FROM core_user, core_useractivity WHERE core_user.id = core_useractivity.user_id AND DATEDIFF(NOW(), created) <= 7 GROUP BY user_id ORDER BY count DESC")
         response_data = dictfetchall(cursor)
         return render_to_response("siteadmin/active_user_table.tmpl",{'response_data': response_data})
elif (b=='1'):
         cursor = connection.cursor()
         cursor.execute("SELECT core_user.id, name, mobile_number, COUNT(*) as count, created FROM core_user, core_useractivity WHERE core_user.id = core_useractivity.user_id AND DATE(created) = DATE(NOW())")
         response_data = dictfetchall(cursor)
         return render_to_response("siteadmin/active_user_table.tmpl",{'response_data': response_data})
else:
         raise Http404

对不起，我现在没有使用django ORM，但我将来会这样做。

Answer 1

您必须在render_to_response调用中添加 context_instance ：

return render_to_response("siteadmin/active_user_table.tmpl",{'response_data': response_data}, context_instance=RequestContext(request))

或者您可以在settings.py中使用 TEMPLATE_CONTEXT_PROCESSORS 元组。将此字符串“django.core.context_processors.request”添加到上下文处理器，每个RequestContext都将包含一个变量请求。

Answer 2

我自己解决了，但感谢ndpu帮助我至少我相信没有其他问题，但有一些设置问题。在这个问题中I have problems with setting up django-pagination。 Alasdair曾提到将“django.contrib.auth.context_processors.auth”添加到TEMPLATE_CONTEXT_PROCESSORS。在添加它时，我得到了正确的预期值。

Answer 3

对于那些使用render shortcut的人并且仍然面临此错误，只需将{'request':request}添加到上下文变量

即可

context = { ..., 'request':request}
return render(request, 'templatename.html', context)

我也较早遇到了这个错误。我收到以下错误：内部服务器错误：/ cancel-email /

我尝试了一些google解决方案，但无法解决，然后终于再次检查我的代码，发现模板文件中存在一个愚蠢的错误。

只需添加：

{% load static %}

位于模板文件的顶部。

Django中的keyError。在模板渲染期间
