Customize from enumize
Extend methods enum to I18n enum in Rails
Add this line to your application's Gemfile:
gem 'enum_render', "~> 1.0"
And then execute:
$ bundle install
# 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"]]
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}
