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

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)

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}}

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

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']
