ruby on rails - Convert serialized-hash to Model attributes -

i have serialized data on activerecord model, , want delegate attributes it. this:

class object < ar::base   serialize :data   delegate :title, to: :data end 

but of course doesn't work hash. there other way?

what want in end this. give activerecord model list of symbols:

[ :title, :size, :color ] 

they transformed getters , setters so:

def title   data[:title] end  def title=(val)   data[:title]= val end 

and represented next rest of ar attributes:

#<model id: 21, title: "foo", size: 4, color: nil> 

you looking store:

class user < activerecord::base   store :settings, accessors: [ :color, :homepage ] end  u = user.new(color: 'black', homepage: '37signals.com') u.color                          # accessor stored attribute u.settings[:country] = 'denmark' # attribute, if not specified accessor
