EnumI18nHelper

Help ActiveRecord::Enum feature to work fine with I18n.

As you know in Rails 4.1.0 , ActiveRecord supported Enum method. But it doesn't work fine with I18n

This gem can help you work fine with Enum and I18n

Installation

Add this line to your application's Gemfile:

gem 'enum_i18n_helper'

And then execute:

$ bundle

Or install it yourself as:

$ gem install enum_i18n_helper

Usage

Required Rails 4.1.x

In model file:

class Order < ActiveRecord::Base
  enum status: { "nopayment" => 0, "finished" => 1, "failed" => 2, "destroyed" => 3 }

  def self.restricted_statuses
    statuses.except :failed, :destroyed
  end
end

You can call:

order = Order.first
order.update_attribute :status, 0
order.status
# > nopayment
order.status_i18n # if you have an i18n file defined as following, it will return "未支付".
# > 未支付

You can also fetch the translated enum collection, if you need to:

Order.statuses_i18n

I18n local file example:

# config/locales/model/order.zh-cn.yml
zh-cn:
  enums:
    order:
      status:
        finished: 完成
        nopayment: 未支付
        failed: 失败
        destroyed: 已删除

Notice

If you want to use enum feature, field of your table can't be named with reference. When it is named with 'reference' and define enum in model file, there will be raised an error as below:

NoMethodError: super: no superclass method `enum' for...

Thanks
