title: Naming REST API of user details informations
body: <p>Suppose you have 2 relational tables: User and UserDetails.
  In the user table you store userId, password, email ecc.
  In the UserDetails table you store other info user-related, such as user preferences, last time logged, last IP ecc. Between User and UserDetails exist a 1-1 relationship, they share the same primary key (userId).</p>
  <p>How do you name your REST API to retrieve UserDetails info of a specific user? Is <strong>/users/userId/userdetail</strong> correct or can you suggest a better API name?</p>
