Not setting default_locale in Rails 3.1.3

application.rb:

config.i18n.default_locale = :en

I have got 3 locales (en,es and ca) And when i go to my console:

I18n.locale => :ca # I guess the first one in the array

I am using Gettext. Somebody got a clue what it could be?

Did you uncomment the following line ?

config.i18n.load_path += Dir[Rails.root.join('my', 'locales', '*.{rb,yml}').to_s]

Rails will take translated text from this location only. But this is for Rails specific translation gem. If you want to set default locale for gettext you need to set as below

Add it to environment.rb

I18n.supported_locales = Dir[File.join(RAILS_ROOT, "locale/*")].collect{|v| File.basename(v)}

Test in a rails console

 ::I18n.locale = 'en'

You can verify this by the following gettext method

GetText.locale.to_s

Basically I set languages by setting I18n.locale = 'en' or any other locale. You can set the default language based on browser preferred language also. You can also force the language to set locale in (gettext) by passing lang='ca', etc. All you need is to use :before_filter. Call the below method in that filter 

def set_default_language
    languages   = get_browser_preferred_languages_hash(request.env["HTTP_ACCEPT_LANGUAGE"])
    @locale     = languages.blank? ? 'en' : app_preferred_language(languages, params[:lang])[0..1]
    I18n.locale = @locale || 'en'
end

  def get_browser_preferred_languages_hash(languages)
    # no language accepted
    return [] if languages.blank?
    # parse Accept-Language
    accepted = languages.split(",")
    accepted = accepted.map { |l| l.strip[0..1]}
  end

  def app_preferred_language(languages,forced_lang)
    unless forced_lang.blank?
      return forced_lang.class == Array ? forced_lang[0] : forced_lang       
    end
    return 'en' if languages.blank?
    @matched_lang = ''
    languages.each do |lang|
      @matched_lang = support_languages_hash.values.detect{|ele| ele[0..1] == lang}
      break if !@matched_lang.blank?
    end
    return @matched_lang.blank? ? 'en' : @matched_lang
  end

  def support_languages_hash
    GetText.locale
    { _('English')    => 'en-US',
      _('Spanish')    => 'es-419',
      _('Catalan')    => 'ca' }
  end

I don't think this is it, but maybe you're overriding config.i18n.default_locale in your environment file, ie. environments/development.rb.

A good start point would be to look for all the occurences of I18n.locale, I18n.default_locale, and related values by grepping. I would start by grep 'locale' app -rn (r for recursive, n to show line numbers), then do it again in the project root.

I'm learning rails. I'm following Pragmatic Agile Web Development with Rails. I was just trying and trying to make localization work and it just didn't work. After some time, I have noticed that in my tests the locale was correct. Weird. Then I realized that the view was cached. So try to remove files in rails_app_path/tmp.

Cheers!

  • I just spent probably 2 hours banging my head against the wall trying to figure out why `config.i18n.default_locale` was not being respected in my app. This is what fixed it. Ridiculous. But thank you. – James Duffy May 23 '14 at 10:37

Add to application.rb this line config.i18n.locale = :ca and Rails will set default locale. It is working for me in production server, but I set :ru locale

  • Hey this is working indeed. But I seriously dont like the solution. Because default_locale is the variable to set... Anyway I accept your answer :) – Michael Koper Feb 26 '12 at 21:27

Your problem is probably related to using Gettext. If I'm not mistaken it uses its own mechanisms for storing and fetching the locale and I suppose it simply doesn't respect any default_locale settings. In case some of you got here because you have had similar problems without Gettext. For you guys I can say that at least with latest stable rails release default_locale works just fine. You have probably redefined it and or explicitly set the locale somewhere. Grep your project for references:

grep -rn default_locale . 
grep -rn I18n.locale .

or smhtn..

Another thing to remember is that server restart is probably needed for the new default_locale setting to have effect.
