我试过类似的方法，但不管用。
class PostSerializer(serializers.ModelSerializer):
class Meta:
model = Post
def save(self):
user = self.context['request.user']
title = self.validated_data['title']
article = self.validated_data['article']
我需要一种能够访问请求的方法。用户从我的Serializer类。

你不能直接访问self.context.user。首先，你必须在序列化器中传递上下文。以下步骤如下:
Some where inside your api view: class ApiView(views.APIView): def get(self, request): items = Item.object.all() return Response( ItemSerializer( items, many=True, context=request # <- this line (pass the request as context) ).data ) Then inside your serializer: class ItemSerializer(serializers.ModelSerializer): current_user = serializers.SerializerMethodField('get_user') class Meta: model = Item fields = ( 'id', 'name', 'current_user', ) def get_user(self, obj): request = self.context return request.user # <- here is current your user

您无法访问该请求。直接用户。您需要访问请求对象，然后获取用户属性。
是这样的:
user = self.context['request'].user
或者为了安全起见，
user = None
request = self.context.get("request")
if request and hasattr(request, "user"):
user = request.user
更多的上下文可以在这里阅读
在GET方法中:
添加context={'user':请求。View类中的user}:
class ContentView(generics.ListAPIView):
def get(self, request, format=None):
content_list = <Respective-Model>.objects.all()
serializer = ContentSerializer(content_list, many=True,
context={'user': request.user})
在Serializer类方法中获取:
class ContentSerializer(serializers.ModelSerializer):
rate = serializers.SerializerMethodField()
def get_rate(self, instance):
user = self.context.get("user")
...
...
POST方法:
遵循其他答案(例如Max的答案)。
你可以通过请求。用户在视图中调用.save(…)时:
class EventSerializer(serializers.ModelSerializer):
class Meta:
model = models.Event
exclude = ['user']
class EventView(APIView):
def post(self, request):
es = EventSerializer(data=request.data)
if es.is_valid():
es.save(user=self.request.user)
return Response(status=status.HTTP_201_CREATED)
return Response(data=es.errors, status=status.HTTP_400_BAD_REQUEST)
这是模型:
class Event(models.Model):
user = models.ForeignKey(to=settings.AUTH_USER_MODEL, on_delete=models.CASCADE)
date = models.DateTimeField(default=timezone.now)
place = models.CharField(max_length=255)
如果你正在使用通用视图，并且你想在保存实例时注入当前用户，那么你可以覆盖perform_create或perform_update:
def perform_create(self, serializer):
serializer.save(user=self.request.user)
User将作为一个属性添加到kwargs中，您可以通过serializer中的validated_data访问它
user = validated_data['user']
