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。
当前回答
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)
其他回答
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']
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
实际上，你不需要考虑上下文。有一个更好的方法:
from rest_framework.fields import CurrentUserDefault
class PostSerializer(serializers.ModelSerializer):
class Meta:
model = Post
def save(self):
user = CurrentUserDefault() # <= magic!
title = self.validated_data['title']
article = self.validated_data['article']
CurrentUserDefault 可用于表示当前用户的默认类。为了使用这个，'request'必须在实例化序列化器时作为上下文字典的一部分提供。
在views.py
serializer = UploadFilesSerializer(data=request.data, context={'request': request})
这是传递请求的示例
在serializers.py
owner = serializers.HiddenField(
default=serializers.CurrentUserDefault()
)

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
