ActsAsCustomizedAttributes

Add custom attributes to your models, which doesn't have predefined names but can be created runtime, and still be able to do queries on that data.

Install

Bundle

Add this to your Gemfile and bundle:

gem 'acts_as_customized_attributes'

Modify model

class SomeModel
  acts_as_customized_attributes

class AddCustomizedAttributesForSomeModel < ActiveRecord::Migration
  def up
    SomeModel.create_customized_attributes!
  end

  def down
    SomeModel.drop_customized_attributes!
  end
end

some_model.update_customized_attributes(my_custom_attribute: 5)

some_model.customized_attributes #=> {:my_custom_attribute => 5}

Query data

    model.update_customized_attributes_with_args(data: {my_custom_attribute: 5}, transactioner: trans)
