self.user = serializer_field.context['request'].user KeyError: 'request

django DRF：

APIView和通用API的细节区别：

 

 使用CurrentUserDefault()时报错：

user = serializers.HiddenField(
    default=serializers.CurrentUserDefault()
) 

 报错如下：

File "C:\Users\sz.yu\Envs\Smartshop\lib\site-packages\rest_framework\fields.py", line 271, in set_context 

self.user = serializer_field.context['request'].user 

KeyError: 'request'

 

这是因为我使用的APIView而不是GenericAPIView（GenericAPIView会自动对context处理，而APIView不会） 

所有视图中序列化应该这样写：

def post(self, request, format=None):
    context = {
        "request":request,
    }
    serializer = UserMessageCreateSerializer(data=request.data, context=context)
    if serializer.is_valid(raise_exception=True):
        serializer.save()
        return Response(serializer.data, status=HTTP_201_CREATED, content_type="application/json")

 额外传递 context=context参数
