python之Django 休息框架 : convert queryset to json response

我有两个模型，Appointment 和 EmployeeEvent。我需要从这些模型中获取数据并将结果合并到一个获取 API 请求中。

网址.py

url(r'^calenderevents', calender_events) 

View .py

@api_view(['GET']) 
def calender_events(request): 
    queryset1 = Appointment.objects.all() 
    queryset2 = EmployeeEvent.objects.all() 
    return Response({'Appointments':json.loads(serializers.serialize('json', queryset1)), 'EmployeeEvents': json.loads(serializers.serialize('json', queryset2))}) 

当我调用 API 时，我得到了结果，但它包含一些不需要的键，如“pk”、“模型”、“字段”等。同样在约会结果中，我需要完整的客户对象而不是客户ID。有什么方法可以指定 CustomerSerializer 和查询集吗？

正在获取结果

请您参考如下方法:

您需要编写序列化器以所需格式显示数据。阅读出色的教程以正确指导您。但是如果你想要一个快速的 hacky 答案，那么做这样的事情:

serializer = AppointmentSerializer(Appointment.objects.all(), many=True) 
return Response(serializer.data) 

序列化程序看起来像这样:

class AppointmentSerializer(serializers.ModelSerializer): 
    customer = CustomerSerializer(required=False, allow_null=True) 
 
    class Meta: 
        model = Appointment 
        fields = ('id', 'customer', 'status', 'etc...') 
        related_object = 'customer' 
 
class CustomerSerializer(serializers.ModelSerializer): 
    class Meta: 
        model = Customer 
        fields = ('id', 'first_name', 'etc...')
