I18n.locale is wrong after I install this gem.

[piya23300]

My rails version is 5.1.4 and r18n gem version is

r18n-core (2.2.0)
    r18n-rails (2.2.0)
      r18n-rails-api (= 2.2.0)
    r18n-rails-api (2.2.0)
      i18n
      r18n-core (= 2.2.0)

At application.rb

config.i18n.default_locale = :th

before I install r18n gem

puts I18n.locale => :th

after I installed r18n gem

puts I18n.locale => :"en-US"

Can you help me?

Thank you in advance.

What files so you have in config/locales and app/i18n?

[piya23300]

I have 2 files at config/locales. en.yml and th.yml

Strange. Where do you put I18n.locale? What do you have in R18n.get?

[piya23300]

Where do you put I18n.locale?

I put it on console (rails console). My view is wrong. I try to debug it.

What do you have in R18n.get?

I can call it. it returns a lot of data.

[ai]

Show me R18n.get.code

[piya23300]

#<R18n::Untranslated:0x007fbaf2251f70 @translated_path="", @untranslated_path="code", @locale=Locale en-US (American English), @filters=#<R18n::GlobalFilterList:0x007fbaefcf2a18>>

What locale will you have in Rails controller in HTTP request from browser with th locale?

[piya23300]

I don't send any locale.

Started GET "/pet_cards/new" for 127.0.0.1 at 2017-12-23 17:57:40 +0700

Put I18n.locale to your controller code or in your view file

[piya23300]

I18n.locale => en-US
18n.default_locale => th

What HTTP_ACCEPT_LANGUAGES header do you have in your browser?

Maybe your can create small Rails project to reproduce the problem, do I will not ask you for many tests 😅?

[piya23300]

{"X-Frame-Options"=>"SAMEORIGIN", "X-XSS-Protection"=>"1; mode=block", "X-Content-Type-Options"=>"nosniff"}

I just create the project 1 week ago - -"

[piya23300]

my repo https://github.com/piya23300/hopet_r18n

URL FOR TEST http://localhost:3000/pet_cards/new

all translations is correct except prompt of select

I expect

At locales/th.yml

datetime:
    prompts:
      day: -- เลือกวัน --
      hour: -- เลือกชั่วโมง --
      minute: -- เลือกนาที --
      month: -- เลือกเดือน --
      second: -- เลือกวินาที --
      year: -- เลือกปี --

but it shows

Day
Month
Year

Here are two different problems:

1. Locale in rails console
2. Locale in controller during a web request.

Let’s fix the first one first. Here is current R18n locale choosing for rails console:

1. Take ENV['LANG'].
2. If ENV['LANG'] is missed, use I18n.default_locale.

So, what is your operation system language? Show puts ENV['LANG']

[piya23300]

irb(main):001:0> ENV['LANG']
=> "en_US.UTF-8"

Oh, I see. >< but I think the gem should use I18n.default_locale the same rails to be a default locale.

http://guides.rubyonrails.org/i18n.html#configure-the-i18n-module

The I18n library will use English as a default locale, i.e. if a different locale is not set, :en will be used for looking up translations.

Thank you to help me and Happy New Year 2018 🎉🎉🎉

Good question. R18n Rails is compatibility layout. But it is not 100% the same since it try to improve I18n 😊.

Because current R18n behavior is public API I can't change it without major version.

Do you really need Rails behavior? I can give you small snippet to ignore ENV.

[piya23300]

Yes, I need it.

because I think gems shouldn't change the behavior of default Rails configuration.

[ai]

Create config/initializers/r18n_fix.rb and put this code:

ActiveSupport.on_load(:after_initialize) do
  locale = I18n.default_locale.to_s
  if defined? Rails::Console and not defined? Wirble
    i18n   = R18n::I18n.new(locale, R18n.default_places,
                            off_filters: :untranslated,
                            on_filters:  :untranslated_bash)
    R18n.set(i18n)
  else
    R18n.set(locale)
  end
end

it will remove ENV usage.

Thank you so much.
