literal_enum

LiteralEnum

Stop using integers in your database when using enums. Use the enum type define in your model for better DX.

Usage

The following class_method is added to your arsenal and now ["pending", "accepted"] are saved as strings in your database.

class Article < ApplicationRecord
  # @NOTE:
  # The column `status` is supposed to be of type string in your database.
  literal_enum :status, ["pending", "accepted"]
end

Installation

Add this line to your application's Gemfile:

gem "literal_enum"

And then execute:

$ bundle

Or install it yourself as:

$ gem install literal_enum

Huge shout-out to hundredwatt!

I was tired of this integer in the database when using enums, and he jumped into the discussion on Twitter and showed me this:

After learning about Rails engines, I thought that this could be a great first gem ;)

The original class_method is actually from the gist by @hundredwatt.
