解决方案可以很简单，但我尝试使用self. contentt ['request']访问。用户，但没有在序列化器中工作。

如果你使用DRF显然登录通过令牌是唯一的来源或其他可能是有争议的。

朝着解决方案前进。

传递请求。创建serializer.create时的用户实例

views.py

if serializer.is_valid():
            watch = serializer.create(serializer.data, request.user)

serializer.py

 def create(self, validated_data, usr):
    return Watch.objects.create(user=usr, movie=movie_obj, action=validated_data['action'])

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)

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)。

正如Igor在其他回答中提到的，您可以使用CurrentUserDefault。如果你不想为此重写save方法，那么使用doc:

from rest_framework import serializers

class PostSerializer(serializers.ModelSerializer):
    user = serializers.PrimaryKeyRelatedField(read_only=True, default=serializers.CurrentUserDefault())
    class Meta:
        model = Post

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

在我的项目中，我的用户字段是只读的，所以我需要得到 创建方法中的用户id

class CommentSerializer(serializers.ModelSerializer):
    comment_replis = RecursiveField(many=True, read_only=True)
    user = UserSerializer(read_only=True)

    class Meta:
        model = PostComment
        fields = ('_all_')

    def create(self, validated_data):
 


        post = PostComment.objects.create(**validated_data)   
        print(self._dict_['_kwargs']['data']["user"]) # geting #request.data["user"] #  <- mian code
        post.user=User.objects.get(id=self._dict_['_kwargs']['data']["user"])
        return post

在我的项目中，我尝试了这种方法，并成功了
