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

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

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']

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}}

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
