我正在尝试使用 Django Rest Framework 和 Ajax 请求来获取用户列表。但是，我收到以下错误

AttributeError: 'UserListViewSet' object has no attribute 'GET'

不知道我做错了什么 - 我对 DRF 比 vanilla Django 更新。

阿贾克斯调用：

const showUserLists = function(map){
  let userName = "Henry";

  $.ajax({
      type: 'GET',
      url: '/api/userlist/',
      data: {
        'username': userName
      },
      success: function (data) {
        data.forEach(item => { 
              console.log(item.list_name)
              $("#userLists").append("<li class=userlist data-name=\"" + item.list_name + "\">" + item.list_name + "</li>")
          })
        }
      });
};

网址.py：

router = DefaultRouter()
router.register('userlist', views.UserListViewSet, basename= 'userlist')
router.register('uservenue', views.UserVenueViewSet, basename= 'uservenue')

视图.py

#this shows all lists for a user
class UserListViewSet(viewsets.ModelViewSet):
    serializer_class = UserListSerializer
 
    def get_queryset(request):
        name = request.GET.get('username', None)
        return UserList.objects.filter(user=name)

追溯：

的第一个参数get_queryset不是请求，而是UserListViewSet，所以self，可以通过 获取请求self.request：

class UserListViewSet(viewsets.ModelViewSet):
    serializer_class = UserListSerializer
 
    def get_queryset(self):
        name = self.request.GET.get('username', None)
        return UserList.objects.filter(user=name)
