In my frontend non-translated strings are replaced with word form of their key instead of the translation of base language.
That means that changing locale to :en or :tr both shows Summaries Header for t('activerecord.misc.badge.summaries_header') instead of Auswertungen from German locale. So it's obviously build from the last part of the key. Summaries Header does not appear as Label in any locale.
Other in :en/:tr translated strings are shown correctly.

# Versions
ruby 2.7.2
rails 5.2.4.4
i18n 1.8.6
rails-i18n 5.1.3
I can't find the reason for that behavior and I can't figure out which update at which time broke this.
How can I fix this?
TL;DR: Update to i18n v1.8.7 or higher with bundle update i18n
i18n v1.8.6 was broken regarding getting fallbacks from config.i18n.* into Thread variables.
See i18n issue #546 and changelog for v1.8.7

I am trying to add a US region specific locale to rails, however tells me that :en_locale is not a valid code for a locale. How can I include this specific region?
In app/config/locales, I have en.yml and en-US.yml.
My application.rb, I have the following:
# The default locale is :en and all translations from config/locales/*.rb,yml are auto loaded.
# config.i18n.load_path += Dir[Rails.root.join('config', 'locales', '*.{rb,yml}').to_s]
config.i18n.available_locales = [:en, :'en-US']
config.i18n.default_locale = :en
config.i18n.fallbacks = [:en]
# config.i18n.fallbacks = {:'zh-MY' => :'zh-CN'} # If we want to designate a lang to fallback to
Error Message:
I18n::InvalidLocale - :en_us is not a valid locale:
i18n (0.6.9) lib/i18n.rb:288:in `enforce_available_locales!'
i18n (0.6.9) lib/i18n/config.rb:11:in `locale='

The i18n library takes a pragmatic approach to locale keys (after some
discussion), including only the locale ("language") part, like :en,
:pl, not the region part, like :en-US or :en-GB, which are
traditionally used for separating "languages" and "regional setting"
or "dialects". Many international applications use only the "language"
element of a locale such as :cs, :th or :es (for Czech, Thai and
Spanish). However, there are also regional differences within
different language groups that may be important. For instance, in the
:en-US locale you would have $ as a currency symbol, while in :en-GB,
you would have £. Nothing stops you from separating regional and other
settings in this way: you just have to provide full "English - United
Kingdom" locale in a :en-GB dictionary. Few gems such as Globalize3
may help you implement it.

In our Rails 4.2 app views, there is I18n error whenever there is no key found in zh-CN file:
translation missing: zh-CN.no key
Here is in local.rb under config/initializers/:
I18n.default_locale = 'zh-CN' if Rails.env.production? || Rails.env.development?
We would like to turn off this error and prevent it from showing on views. There is a post about the error for Rails 3. However the solutions are not working with Rails 4.2. Also config.i18n.fallbacks = false/true does not do the trick.
You must add both a fallback locale and a fallback language.
config.i18n.default_locale = :en
config.i18n.fallbacks = true
This should force I18n to fallback to english. I use it extensively on a Rails 4.1 app, I'm not sure if something changed over it for 4.2 though.
We can config I18n callbacks in Rails application. For example, when zh-CN translation missing, I18n will fallback to en. Configuration in my Rails 4.2.2 application like below:
config/application.rb
config.i18n.load_path += Dir[Rails.root.join('config', 'locales', '**', '*.{rb,yml}').to_s]
config.i18n.default_locale = :"zh-CN"
config.i18n.fallbacks = true
config/initializers/i18n.rb
Rails.configuration.after_initialize do
I18n.fallbacks.map(:"zh-CN" => :en)
end

I am working on a rails app (3.2.13) that is being translated into several languages, including (one of the 3 available flavours of) Norwegian. On public pages, the app uses the browser's language settings to set locale.
Most browsers offer 3 separate Norwegian shortcodes: no, nb & nn. The translations we have are in nb, but I think it would be best if no & nn also defaulted to nb. That way, if a user's browser language preferences were set to no then en, the app would try to supply nb Norwegian first, instead of skipping straight to English.
Is it possible to configure a list of "language aliases" for the i18n gem, something like this?
config.i18n.available_locales = [:sv, :en, :nb, :da, :fi]
config.i18n.aliased_locales = [:nb <= :no, :nb <= :nn]
Short answer
Take a look to the fallbacks
Create a file in initializers like i18n_fallbacks.rb
config.i18n.fallbacks = {:no => [:nb], :nn => [:nb]}
Here the reference

You can even set multiple fallbacks, and they will be taken in the same order as specified:
for instance:
config.i18n.default_locale = :de
config.i18n.fallbacks = {:de => [:en,:es]}
de.yml
:de:
greeting: Hallo
en.yml
:en:
foo: bar
es.yml
:es:
bar: baz
You get the following:
I18n.t :greeting # found in de.yml, no fallback
# => 'Hallo'
I18n.t :foo # not in :de, try in :en and found
# => "bar"
I18n.t :bar # not in :de, try in :en and in :es
# => "baz"
I81n.t :other # not found anywhere, note the message delivers not found for the current locale:
# => "translation missing: de.other"
In latest i18n gem (0.7.0) I have found it necessary to define fallback locales like this (in config/application.rb):
# Custom I18n fallbacks
config.after_initialize do
I18n.fallbacks = I18n::Locale::Fallbacks.new(at: :"de-DE", ch: :"de-DE", gb: :"en-US")
end
You also need to set config.i18n.fallbacks = true in all config/environments/*.rb files.
Edit: (to be clear and to the point)
I want the following to work on heroku: "11/13/2011".to_datetime, meaning I need the dates to be in english format. Thanks
I've set this the i18n locale in my application.rb
config.i18n.default_locale = :en
config.i18n.locale = :en
In the heroku console:
I18n.locale
=> :en
So it seems like it's set correctly.
But when I do:
"11/13/2011".to_datetime
=> ArgumentError: invalid date
Noooo!
Do you have any idea of what I'm doing wrong here?
Thanks.
The i18n config had nothing to do with my problem.
Just a ruby version "problem".
I was working with ruby 1.8.7 in my local env, and heroku was at 1.9.x.
Rails 1.9 assumes EU format, 1.8.7 does not.
I'm using Rails 3 with Globalize3 0.2.0.beta4
Ideally I need :fr to fallback to :en and vice versa.
There are cases when only a French translation is available and I need to show it even if the locale is :en.
I tried
config.i18n.fallbacks = { :fr => :en, :en => :fr }
but somewhat unsurprisingly it causes a stack level too deep error.
I'm changing my answer.
To enable fallbacks, add the following to your environment.rb file:
#support for locale fallbacks
require "i18n/backend/fallbacks"
I18n::Backend::Simple.send(:include, I18n::Backend::Fallbacks)
Then, you can enable circular fallbacks like you were trying to, eg:
config.i18n.fallbacks = {'en' => 'fr', 'fr' => 'en'}
In this case, if something is missing in the en locale, it'll check the fr locale, and then the other way around. I don't get any errors running this.
Source: http://batsov.com/articles/2012/09/12/setting-up-fallback-locale-s-in-rails-3/
If you pass an array of locales they will be set as default fallbacks for all locales.
config.i18n.fallbacks = [:en, :fr]
Unfortunately, I haven't found a way to set up just two locales to fall back to each other.
In the end I monkey patched Globalize3. Not great as I have to update the patch whenever the site needs a new locale, but hey, it worked.
module Globalize
class << self
def fallbacks(locale = self.locale)
case locale
when :en then [:en, :fr]
when :fr then [:fr, :en]
end
end
end
end
This seems to have changed to this:
Globalize.fallbacks = {:en => [:en, :fr], :fr => [:fr, :en]}
Got from the official docs:
https://github.com/globalize/globalize#fallback-locales-to-each-other
In latest i18n gem (0.7.0) I have found it necessary to define fallback locales like this (in config/application.rb):
# Custom I18n fallbacks
config.after_initialize do
I18n.fallbacks = I18n::Locale::Fallbacks.new(at: :"de-DE", ch: :"de-DE", gb: :"en-US")
end
You also need to set config.i18n.fallbacks = true in all config/environments/*.rb files.
