创建新模型类django时模型中的OneToOneField错误 [英] Error at OneToOneField in models while creating new models class django

问题描述

在创建新模型类时，我面临以下错误。
仅在此行弹出错误 user = models.OneToOneField（User）
E1120：构造函数调用中参数'on_delete'没有值

I am facing below error while creating a new model class. the error pop up only at this line "user = models.OneToOneField(User)" "E1120:No value for argument 'on_delete' in constructor call"

section / models.py

section/models.py

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

class userProfile(models.Model):
    user = models.OneToOneField(User)

admin.py

from django.contrib import admin
from section.models import userProfile

admin.site.register(userProfile)

如果我在下面的条目中添加 on_delete = models.CASCADE

If I add below entry with "on_delete=models.CASCADE"

user = models.OneToOneField(User,on_delete=models.CASCADE)

错误消失了，但是新的类 userProfile没有出现在管理页面的用户标签下

the error got subsided but the new class "userProfile" is not appearing in admin page, under Users tab.

还运行迁移：

C:\Users\srini\djangoProjects\college>python manage.py makemigrations
No changes detected

C:\Users\srini\djangoProjects\college>python manage.py migrate
Operations to perform:
Apply all migrations: admin, auth, contenttypes, sessions
Running migrations:
No migrations to apply.

有人可以指导我如何解决这个问题吗？

Could some one please guide me how to fix this ?

推荐答案

将您的app_name包含在settings.py的 INSTALLED_APPS 列表中。

Include your app_name in INSTALLED_APPS list in settings.py.

然后尝试迁移。之后，在运行服务器后检查Admin。

Then try migrations. After that check Admin after running the server.
