docs: The default method that takes a `params` object and converts
  it into an object.
  
  By default, a params hash that looks like `{ post_id: 1 }`
  will be looked up as `namespace.Post.find(1)`. This is
  designed to work seamlessly with Ember Data, but will work
  fine with any class that has a `find` method.
