我正在尝试访问名为Active\u Project\u View的数据库。这里面是我试图在ag网格中显示的信息。我用了objects.all()来获取信息，但它不起作用

class getActiveGrid():
    def get_queryset(self, request, format=None):
        queryset = Active_Project_View.objects.all()
        return queryset

    def get(self, request, format=None):
         filters = request.data
         serializer = ActiveGridViewSerializer(self.get_queryset(filters), many=True)
         return HttpResponse(serializer.data)

<h1>Project Grids</h1>

<div class="box c">

活动项目 你知道吗

  <script type="text/javascript" charset="utf-8">

    const Active_Project = [
        { headerName: "Last Name", field: "app.Customer_Last_Name", sort: 'asc' },
        { headerName: "First Name", field: "Customer_First_Name", },
        { headerName: "Phone Number", field: "Customer_Phone_Number", },
        { headerName: 'Employee', field: 'Employee_First_Name' },
        { headerName: 'Zip Code', field: 'Customer_Zip' },
       ];

   const ActiveProjectGrid = {
        columnDefs: Active_Project,
      };


    var eGridDiv1 = document.querySelector('#ActiveProjectGrid');     
    new agGrid.Grid(eGridDiv1, ActiveProjectGrid);

      fetch('getActiveGrid').then(function (response) {
          return response.data();
      }).then(function (data) {
          ActiveProjectGrid.api.setRowData(data);
          })
  </script>
</body>
</html>


url(r'^getActiveGrid$',app.views.getActiveGrid, name='postActive'),


class ActiveGridViewSerializer():
    class Meta:
    model = Active_Project_View
    fields= '__all__'

类活动项目视图（models.Model）：

id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
Customer_First_Name= models.CharField(max_length=255, blank = False)
Customer_Last_Name = models.CharField(max_length=255, blank = False)
Customer_Phone_Number = models.CharField(max_length=10, blank=True) 
Customer_Zip = models.CharField(max_length = 5, blank = False)
Employee_First_Name=models.CharField(max_length=255)
Quote_Status = models.CharField(max_length = 16, default = None)

class Meta:
    managed = False

我希望得到客户的姓名，电话号码，邮政编码和员工显示是网格。我目前得到的“加载…”框，我不知道我做错了什么

您的实现存在多个问题。你可以这样一个接一个地修复它们：

from rest_framework.views import APIView
from rest_framework.response import Response
from rest_framework import serializers

#serializer
class ActiveGridViewSerializer(serializers.ModelSerializer):
    class Meta:
        model = Active_Project_View
        fields= '__all__'

# view
class getActiveGrid(APIView):
    def get_queryset(self):
        queryset = Active_Project_View.objects.all()
        return queryset

    def get(self, request, format=None):
         serializer = ActiveGridViewSerializer(self.get_queryset(), many=True)
         return Response(serializer.data)

# url
url(r'^getActiveGrid$',app.views.getActiveGrid.as_view(), name='postActive'),
