我试图通过views.py路由AJAX GET请求并将其返回到模板，但只显示与登录用户连接的对象项

我正试图使用filter()，但出现以下错误：'User' object is not iterable

下面是views.py类：

class user_playlist(ListView):
    template_name = 'testingland/dashboard.html'
    context_object_name = 'playlist'
    model = UserVenue

    def get_queryset(self):
        venue = self.request.GET.get('venue', None)
        list = self.request.GET.get('list', None)

        return UserVenue.objects.filter(self.request.user)

型号：

class UserVenue(models.Model):
    venue = models.ForeignKey(mapCafes, on_delete=models.PROTECT)
    list = models.ForeignKey(UserList, on_delete=models.PROTECT)

class UserList(models.Model):
    list_name = models.CharField(max_length=255)
    user = models.ForeignKey(User, on_delete=models.CASCADE) 

    def __str__(self):
        return self.list_name

以下是模板：

<body>
    {% block content %}
        <div class="container-fluid" style="padding:15px">
            <!--location -->
            <div class="row">
              <div class="col-sm-3" id="playlist"></div>
                <ul class = "cafe-playlist">
                  {% for item in playlist %}
                    <li>
                      <div>
                          <h6 class="playlist-name">{{ item.list }}</h6>
                      </div>
                  </li>
                  {% endfor %}
                </ul>
              </div>
    {% endblock %}

下面是AJAX对良好措施的呼吁：

//dashboard
$(document).ready(function(){
    console.log('Document Ready')
    $.ajax({
            type: "GET",
             url : '/electra/playlist',
             dataType: "json",
             data: {
                 'venue': 'venue',
                 'list':  'list',
                },
                    success: function(data){
                    $("#playlist").html(data);
                    console.log(data)
                    },
                    failure: function(errMsg) {
                        alert(errMsg);
                    }
    });
    });

对于那些感兴趣的人，这里是完整的回溯：

使用此查询

 return UserVenue.objects.filter(list__user=self.request.user)
