title: Laravel 4 One to One relationship
body: <p>I would like to have a one to one relationship with a pivot table or by referencing an ID in a table.</p>
  
  <p>I currently have a Films table that has a one to many relationship with a Stock table, each stock item needs a format, however I would like the formats to be a set list of formats so I created a Formats table that only has 2 columns ID and Name</p>
  
  <p>Normally I would just add a Format_ID column to the Stock table however I'm unsure how this would work with the Eloquent ORM or if it's even possible / best practice</p>
  
  <p>Sorry if this is hard to understand, cant quite figure out the best way of explaining it</p>
