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

在视图中使用以下代码:

serializer = UploadFilesSerializer(data=request.data, context={'request': request})

然后在序列化器中使用这个访问它:

user = self.context.get("request").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

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)

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()
)
