title: Wishlist relationships in Rails?
body: <p>Im building an app where Users have some sort of wishlist</p>
  
  <p>a User can have only one wishlist, and can add existing Items to that wishlist
  however the Items belong to other Users on the site</p>
  
  <p>I need to be able to access the wishlist items through current_user.wishlist.items (im using Devise so current_user is available)</p>
  
  <p>i though of adding a wishlist_id column to the items table, but that wouldnt work since items can belong to multiple wishlists.</p>
  
  <p>this seems simple but im having a hard time visualizing the relationship or the migration im supposed to generate</p>
