对于那些使用Django ORM并将用户添加为外键的人，他们将需要包括用户的整个对象，而我只能在create方法中做到这一点，并删除必选字段:

class PostSerializer(serializers.ModelSerializer):

def create(self, validated_data):
    
    request = self.context.get("request")
    
    post = Post()
    post.title = validated_data['title']
    post.article = validated_data['article']
    post.user = request.user

    post.save()

    return post

class Meta:
    model = Post
    fields = '__all__'
    extra_kwargs = {'user': {'required': False}}

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

你需要在你的序列化器中做一个小编辑:

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']

下面是一个使用Model混合视图集的示例。在create方法中，您可以找到调用序列化器的正确方法。Get_serializer方法正确地填充上下文字典。如果需要使用视图集上定义的不同的序列化器，请参阅update方法，了解如何使用上下文字典初始化序列化器，该方法还将请求对象传递给序列化器。

class SignupViewSet(mixins.UpdateModelMixin, mixins.CreateModelMixin, viewsets.GenericViewSet):

    http_method_names = ["put", "post"]
    serializer_class = PostSerializer

    def create(self, request, *args, **kwargs):
        serializer = self.get_serializer(data=request.data)
        serializer.is_valid(raise_exception=True)
        self.perform_create(serializer)
        headers = self.get_success_headers(serializer.data)
        return Response(serializer.data, status=status.HTTP_201_CREATED, headers=headers)

    def update(self, request, *args, **kwargs):
        partial = kwargs.pop('partial', False)
        instance = self.get_object()
        kwargs['context'] = self.get_serializer_context()
        serializer = PostSerializer(instance, data=request.data, partial=partial, **kwargs)
        serializer.is_valid(raise_exception=True)
        self.perform_update(serializer)    
        return Response(serializer.data)

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

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'])
