Question

在尝试从数据库获取并返回数据时遇到错误。我正在使用switchableControllerActions返回查询集。我正在使用的命令是get_queryset()，但出现错误'BaseList'对象没有属性'items'。

我认为这是由于数据库中的数据所致，我的数据库data = MyModel.objects.filter(account_id=account_id)中有这种格式的数据

Is it due to result has list of dicttionaries

models.py

{
"result" : [ 
        {
            "savings" : 43.0548666420733,
            "count" : 18
        }, 
        {
            "savings" : 387.651510654053,
            "count" : 161
        }],
    }

views.py

from mongoengine import Document, fields


class MyModel(Document):
    result = fields.DictField()

serializers.py

class MyModelViewset(viewsets.ModelViewSet):

    renderer_classes = [renderers.JSONRenderer]
    serializer_class = MyModelSerializer

    def get_queryset(self):
        try:
            data = MyModel.objects.filter(account_id=self.kwargs['account_id'])
            return data
        except Exception as e:
            logger.exception(e)

urls.py

class MyModelSerializer(serializers.DocumentSerializer):
class Meta:
    model = MyModel
    fields = '__all__

由于我怀疑错误来自数据库。我已经更改了

    {
"result" : [ 
        {
            "savings" : 43.0548666420733,
            "count" : 18
        }, 
        {
            "savings" : 387.651510654053,
            "count" : 161
        }],
    }

对此

    {
"result" : {"data":[ 
        {
            "savings" : 43.0548666420733,
            "count" : 18
        }, 
        {
            "savings" : 387.651510654053,
            "count" : 161
        }]}
    }

，现在一切正常。 基本上，result的类型为array，我已将其转换为类型object
