我的序列化器：

class TaskSerializer(serializers.ModelSerializer):
    class Meta:
        model = Task
        fields = "__all__"

    def create(self, validated_data):
        try:
            print(validated_data)
            print(validated_data.author)
            task = Task.objects.create(**validated_data)
            return task
        except BaseException as e:
            print(e)
            raise HTTP_400_BAD_REQUEST

字符串
我的看法：

class TaskCreateApiView(generics.CreateAPIView):
    serializer_class = TaskSerializer

型
我的模型：

from django.db import models
from django.contrib.auth.models import User

class Task(models.Model):
    content = models.CharField(
        default="",
        max_length=255,
    )
    author = models.ForeignKey(
        User,
        on_delete=models.CASCADE,
        null=True,
    )
    category = models.CharField(
        default="",
        max_length=255,
    )

    def __str__(self):
        return str(self.id) + self.content

型
我从序列化器的日志：
请输入'content'：'test 2'，'category'：'test'，'author'：<User: zaq1>}
“dict”对象没有属性“author”print（validated_data.author）^^
如何访问author？我看到它以<User:zaq1>的形式存在，但似乎无法访问它
