title: Add onetoone field to all users, django
body: <p>In the middle of the project, I was faced with the fact that I needed to expand my user model. Since it is very problematic to create a custom model at the moment, I decided to use the onetoone field and everything is successful, but there is a question. I would like to add a relationship to my user model proxy for existing users and set permissions for them. How can I do that? I need to set start value for all users</p>
  <pre><code>class UserPermission(models.Model):
      user = models.OneToOneField(User, on_delete=models.CASCADE)
      start = models.BooleanField(default=True)
      professional = models.BooleanField()
      team = models.BooleanField()
      last_update = models.DateTimeField()
  
  </code></pre>
