def fetch

def find by_name=""
  return fetch if singleton?
  where(name: by_name).first
end

#where(has_attributes = {}) ⇒ Object

Find all objects of this type matching the given search criteria. Uses the all() method to scope calls from within the proper JSON for this class, and instantiates objects based on the found information, so you get back an Array of whatever object this model happens to be. If none, this returns an empty Array.
