title: Laravel get related data from 3 tables
body: <p>I have three tables: <code>users, emails,attachments</code>. User table is connected with emails by user_id. Emails table is connected with attachments by email_id.</p>
  
  <p>My question is: How should I make it look eloquent in laravel to get all users their emails and their attachments? (I know how get all user and they emails but I don't know how to add attachments.)</p>
