title: Combining models within a single page in the admin page
body: <p>I have a User class, and each user has a PersonalInformation model and a Profile model.</p>
  
  <p>In my admin panel I have:</p>
  
  <p>AUTHENTICATION AND AUTHORIZATION
  Users
  Groups</p>
  
  <p>USERS
  Profiles
  Personal Informations</p>
  
  <p>Users have a ONE-ONE relationship with 'PersonalInformation' and 'Profile', but the two models do not have a relationship.</p>
  
  <p>So I can view the Users, the PersonalInformation and Profile models separately, but I want to join them so I can view all one users information on one page.</p>
  
  <p>Thank you.</p>
