Question

我只想让多个ssh-session与每个用户相关联

 from django.contrib.auth.models import User

 class Sshsession(models.Model):
  session_name=models.CharField(max_length=20)
  # Other session attributes
  usr=models.ForeignKey(User)

当我迁移时，我收到错误

 int() argument must be a string or a number, not 'User'

我尝试过做User.id但没有帮助。

Django用户为ForeignKey错误
