PrefixStore

PrefixStore is an ActiveRecord extension to give an addictional method prefix_store_accessor which creates store_accessor getters and setters with prefix named by column.

Usage

Default:

# == Schema Information
#
# Table name: Car
#
#  id                                   :integer          not null, primary key
#  user_id                              :integer
#  name                                 :string(255)
#  spec                                 :json             default({}), not null
#

class Car < ActiveRecord::Base

    store_accessor  :spec,
                    :engine,
                    :v_max_km,
                    :country
    
    ...
end

$ [1] pry(main)> Car.last.v_max_km
$ Car Load (1.5ms)  SELECT "cars".* FROM "cars" ORDER BY "cars"."id" DESC LIMIT 1
$ => "225"

Solution with a prefix accessor:

# == Schema Information
#
# Table name: Car
#
#  id                                   :integer          not null, primary key
#  user_id                              :integer
#  name                                 :string(255)
#  spec                                 :json             default({}), not null
#

class Car < ActiveRecord::Base

    prefix_store_accessor   :spec,
                            :engine,
                            :v_max_km,
                            :country
    
    ...
end

$ [1] pry(main)> Car.last.spec_v_max_km
$ Car Load (1.5ms)  SELECT "cars".* FROM "cars" ORDER BY "cars"."id" DESC LIMIT 1
$ => "225"
