@todesking serialize 使うとそれっぽいことができます

If you have an attribute that needs to be saved to the database as an object, and retrieved as the same object, then specify the name of that attribute using this method and it will be handled automatically. The serialization is done through YAML . If class_name is specified, the serialized object must be of that class on retrieval or SerializationTypeMismatch will be raised. Parameters attr_name - The field name that should be serialized. class_name - Optional, class name that the object type should be equal to. Example # Serialize a preferences attribute class User < ActiveRecord :: Base serialize :preferences end
