Problem with locales containing underscores

[krukgit]

The locale.gsub('_', '-') i18n hack is preventing the page from loading on Rails 4.2.3 and i18n 0.7.0

2.1.5 :010 > I18n.available_locales
 => ["en", "th", "zh_CN", "zh_HK"] 
2.1.5 :011 > I18n.locale = :en
 => :en 
2.1.5 :012 > I18n.locale
 => :en 
2.1.5 :013 > I18n.locale = :zh_HK
 => :zh_HK 
2.1.5 :014 > I18n.locale 
 => :"zh-HK" 

This results in I18n::InvalidLocale: :"zh-HK" is not a valid locale exception.

Monkey patching I18n to remove this hack fixes the problem.

you can turn off the enforce_available_locales ... not sure if that just silences or fixed the problem ...

I think the hack is there to make gettext locales look like i18n locales for compatibility ... maybe also patch available_locales ... or just the place that raises the exception ...

alternatively remove the hack and see which tests blows up ...

@krukgit What ended up working for you? I'm running into the same issue.

This seems to be working for me.

In the initializer I have:

module I18n
  class Config
    def locale
      FastGettext.locale.to_sym
    end
  end
end

In the application.rb I changed our I18n config to use underscores instead of hyphens:

config.i18n.available_locales = [:en, :fr, :de, :nl, :es, :it, :nl_BE]

I renamed our nl-BE.yml to nl_BE.yml`

So far this looks to be working.
