how would I do such a thing? I want to be able to store the params object into a string attribute of a model, and be able to deserialize it into params hash object again, how would I do this in ruby? or is there an out of the box solution in rails?
Active Record can serialize any object in text columns using YAML. To do so, you must specify this with a call to the class method serialize. This makes it possible to store arrays, hashes, and other non-mappable objects without doing any additional work.
class User < ActiveRecord::Base
serialize :preferences
end
user = User.create(preferences: {background: "black", display: "large"})
User.find(user.id).preferences
# => {background: "black", display: "large"}
Mori's answer is correct, but if your data type in the model is truly a string, it may not fit. Suggest you use text instead.
