因此，我使用REST框架创建了“ API”，现在尝试对其进行过滤。那就是我models.py或多或少的样子：

class Airline(models.Model):
    name = models.TextField()

class Workspace(models.Model):
    airline = models.ForeignKey(Airline)
    name = models.CharField(max_length=100)

class Passenger(models.Model):
    workspace = models.ForeignKey(Workspace)
    title = models.CharField(max_length=200)

因此，我想在我的JSON文件中看到“特定工作区中的所有乘客”或“特定航空公司中的所有乘客”等。

这是我的， serializers.py

class AirlineSerializer(serializers.ModelSerializer):
    class Meta:
        model = Airline


class WorkspaceSerializer(serializers.ModelSerializer):
    class Meta:
        model = Workspace


class PassengerSerializer(serializers.ModelSerializer):
    class Meta:
        model = Passenger

和views.py：

class AirlineList(generics.ListCreateAPIView):
    model = Airline
    serializer_class = AirlineSerializer


class AirlineDetail(generics.RetrieveUpdateDestroyAPIView):
    model = Airline
    serializer_class = AirlineSerializer


class WorkspaceList(generics.ListCreateAPIView):
    model = Workspace
    serializer_class = WorkspaceSerializer


class WorkspaceDetail(generics.RetrieveUpdateDestroyAPIView):
    model = Workspace
    serializer_class = WorkspaceSerializer


class PassengerList(generics.ListCreateAPIView):
    model = Passenger
    serializer_class = PassengerSerializer


class PassengerDetail(generics.RetrieveUpdateDestroyAPIView):
    model = Passenger
    serializer_class = PassengerSerializer

这是我第一次使用REST框架，我检查了文档，他们帮助了我到目前为止所做的一切，我想使用

根据查询参数进行过滤：http : //www.django-rest-
framework.org/api-guide/filtering/#filtering-against-query-
parameters

真的不能得到它..
