如何修復Django中的“object（）不帶參數”錯誤

Question

我正在嘗試訪問名為Active_Project_View的數據庫。 其中包含我試圖在ag-grid中顯示的信息。 我已經使用了objects.all()來獲取信息，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)

    new agGrid.Grid(eGridDiv1, ActiveProjectGrid);

      fetch('getActiveGrid').then(function (response) {
          return response.data();
      }).then(function (data) {
          ActiveProjectGrid.api.setRowData(data);
          })

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


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

class Active_Project_View（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

我希望得到的客戶名稱，電話號碼，郵政編碼和員工要顯示的是網格。 我目前正在收到“loading ...”框，我不確定我做錯了什么。

您的實施存在多個問題。 你可以像這樣一個一個地修復它們：

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'),
