title: Allow user to edit their own data with device
body: <p>I know there's probably solutions to this elsewhere, but I'm looking for help that works specifically in my case because I'm having a lot of trouble translating other solutions into my situation. </p>
  
  <p>I currently have a device set up and the database is seeded so an admin is already created. Everyone else that signs up after that is a user. </p>
  
  <p>There are two tables right now, a user table generated by rails and a cadet table. The cadet table stores information such as <code>company</code>, <code>room number</code>, <code>class year</code> and such. </p>
  
  <p>My question is, how do I allow a user to edit/destroy only the cadet record that they've created? I know it seems like a big question but I've been looking all over and still can't find a reasonable way to implement this. Thank you!</p>
