(the basic structure is from <app>.models import <ModelName>)
（基本结构是from <app>.models import <ModelName>）
update:
更新：
the problem is (almost!) certainly that your model begins with '7' -- change it to a letter character, and all will be well, I'm (almost!) sure :)
问题是（几乎！）当然，您的模型以“7”开头 - 将其更改为字母字符，一切都会好起来的，我（几乎！）确定:)

from django.db import models
from django.contrib.auth.models import User
class register(models.Model):
user = models.OneToOneField(User)
Then in your views.py, you can call like this :
然后在您的views.py，您可以这样调用：
from library.models import register
