Allow different types of data in the same field - Ruby On Rails

  • 772

I have a logic query that I'm not sure how to solve, I'm doing a kind of survey, in which, when creating the questions, I need to specify the type of response that it will receive, either a text string , a boolean data, a numeric data, etc. However, I have the database field saved by default as "string", within the "Answer" table, how could I allow any type of data, specifically in the field called "response" and that at the time from calling it on view return as such? I appreciate your suggestions

question.rb

class CreateQuestions < ActiveRecord::Migration[5.2]
  def change
    create_table :questions do |t|
      t.string :title
      t.references :survey, foreign_key: true

      t.timestamps
    end
  end
end

answer.rb

class CreateAnswers < ActiveRecord::Migration[5.2]
  def change
    create_table :answers do |t|
      t.string :response
      t.references :question, foreign_key: true

      t.timestamps
    end
  end
end

    What I would do is serialize the field.

    class Answer < ActiveRecord::Base
  serialize :response
end

    And in the db leave the field as t.text :responseinstead of string, so you would save any type of data in the same field, including hashes or objects, and then you would recover it as it is when consulting them.
