Exists for compatibility with old json library which allows creation of arbitrary ruby objects by JSON.parse. Creates a new instance and populates it using InstanceMethods#from_json_node with the :all_columns and :all_associations options. Not recommended for usage in new code, consider calling the from_json method directly with the JSON string.
