【问题描述】:
我在my reg_group 应用程序的models.py 中创建了一个AbstractUser 类
from django.contrib.auth.models import AbstractUser
from django.db import models
from django.utils.html import escape, mark_safe
class User(AbstractUser):
is_client = models.BooleanField(default=False)
is_agency = models.BooleanField(default=False)
is_vendor = models.BooleanField(default=False)
email = models.EmailField(max_length=255, default=None, blank=True, null=True)
class User_Info(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True)
def __str__(self):
return self.user.name
我还有另一个应用程序notification,其models.py 是这样的:
from django.db import models
from swampdragon.models import SelfPublishModel
from .serializers import NotificationSerializer
class Notification(SelfPublishModel, models.Model):
serializer_class = NotificationSerializer
message = models.TextField()
当我运行python manage.py runserver 时出现错误
django.core.exceptions.FieldError:“用户”类中的本地字段“电子邮件”与基类“AbstractUser”中名称相似的字段发生冲突
但notification 数据库中没有email 字段。
数据库的原始代码是这样的:
CREATE TABLE "notifications_notification" (
"id" integer NOT NULL PRIMARY KEY AUTOINCREMENT,
"level" varchar(20) NOT NULL,
"actor_object_id" varchar(255) NOT NULL,
"verb" varchar(255) NOT NULL,
"description" text,
"target_object_id" varchar(255),
"action_object_object_id" varchar(255),
"timestamp" datetime NOT NULL,
"public" bool NOT NULL,
"action_object_content_type_id" integer,
"actor_content_type_id" integer NOT NULL,
"recipient_id" integer NOT NULL,
"target_content_type_id" integer,
"deleted" bool NOT NULL,
"emailed" bool NOT NULL,
"data" text,
"unread" bool NOT NULL,
FOREIGN KEY("recipient_id") REFERENCES "reg_group_user"("id") DEFERRABLE INITIALLY DEFERRED,
FOREIGN KEY("target_content_type_id") REFERENCES "django_content_type"("id") DEFERRABLE INITIALLY DEFERRED,
FOREIGN KEY("actor_content_type_id") REFERENCES "django_content_type"("id") DEFERRABLE INITIALLY DEFERRED,
FOREIGN KEY("action_object_content_type_id") REFERENCES "django_content_type"("id") DEFERRABLE INITIALLY DEFERRED
);
当然是auto-generated。
我不明白为什么没有这样的公共字段时会出现字段冲突错误?
【问题讨论】:
-
公共字段“email”是否也在 abstractUser 或其父项中定义?这就是错误告诉你的字面意思
-
怎么是普通字段
-
它在
notification.model中不存在 -
不是您的通知模型。您继承自 AbstractUser 已经有一个电子邮件字段
-
这与通知无关。错误在用户中,它正在重新定义它从抽象用户继承的电子邮件字段。
