Method: Resourceful::Serialize.normalize_attributes

Defined in:
lib/resourceful/serialize.rb

.normalize_attributes(attributes) ⇒ Object

Takes an attributes option in the form passed to Builder#publish and returns a hash (or nil, if attributes is nil) containing the same data, but in a more consistent format. All keys are converted to symbols, and all lists are converted to hashes. For example:

Resourceful::Serialize.normalize_attributes([:foo, :bar, {"baz" => ["boom"]}])
  #=> {"baz"=>["boom"], :foo=>nil, :bar=>nil}
