Customize from enumize

EnumRender

Extend methods enum to I18n enum in Rails

Installation

Add this line to your application's Gemfile:

gem 'enum_render', "~> 1.0"

And then execute:

$ bundle install

Usage

  # app/model/event.rb
class Event
  enum status: {pending: 0, approved: 1, declined: 2}
end

In I18n translate file:

# config/locales/en.yml
en:
  enums:
    event:
      status:
        pending: "Pending"
        approved: "Approved"
        declined: "Declined"

# config/locales/ja.yml
ja:
  enums:
    event:
      status:
      pending: "保留中"
      approved: "承認済み"
      declined: "辞退"

We have methods: Event.statuses and Event.first.status

After install we have methods:

[2] pry(main)> Event.status_options
[{"key"=>"pending", "value"=>"保留中"}, {"key"=>"approved", "value"=>"承認済み"}, {"key"=>"declined", "value"=>"辞退"}]

[6] pry(main)> Event.first.status_option
{"key"=>"approved", "value"=>"承認済み"}

[9] pry(main)> Event.first.status_name
=> "承認済み"

[8] pry(main)> Event.first.status_value
=> 1

[10] pry(main)> Event.status_select
=> [["保 留 中 ", "pending"], ["承 認 済 み ", "approved"], ["辞 退 ", "declined"]]

Add validate for enum

Issues: rails/rails#13971

Currently, if a "bad" value (say, "canceled") is passed in, an ArgumentError is raised.

After install you can validate them by inclusion validates

  # app/model/event.rb
  class Event
    enum status: {pending: 0, approved: 1, declined: 2}

    validates :status, presence: true, inclusion: {in: statuses.keys}
  end
