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.
