Every URL generated in my Rails app has ?locale=en appended to it. I don't understand it and I don't want it. How can I remove it?
I do not set "default_url_options" in application_controller.rb
Here is the content of my config/application.rb
config.i18n.available_locales = %i[en es]
config.i18n.default_locale = :en
config.i18n.fallbacks = [I18n.default_locale]
config.i18n.fallbacks = true
My Setup:
- Rails 6.0.2.2
- Ruby 2.7.0
- Globalize gem

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.
# config/application.rb
config.i18n.default_locale = :de
config.i18n.available_locales = [
:de, # Deutsch
:pt, # Portugiesisch
:en, # Englisch
:tr, # Türkisch
]
config.i18n.fallbacks = true
# 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
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 have tried everything to make the i18n Fallback on Heroku but I couldn't.
I don't want to get the "translation missing messages". It work OK on developement mode.
Please help!
thanks
require "i18n/backend/fallbacks"
I18n::Backend::Simple.send(:include, I18n::Backend::Fallbacks)
I18n.fallbacks.map(:es => [:en])
config.i18n.fallbacks = true
I have this in my application.rb file:
config.i18n.fallbacks = [:en]
and I just commented this code in production.rb:
config.i18n.fallbacks = true
and it's working ok for me in heroku.
In config/enviroments/production.rb
class Appname::Application.configure do
# Enable locale fallbacks for I18n (makes lookups for any locale fall back to
# the I18n.default_locale when a translation can not be found)
config.i18n.fallbacks = true
end
how to use rails i18n fallback features
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.
So that's the problem. In my application globalize2 returns a NIL string if there's no translation on some record, instead of falling back to default_locale. I wonder how to enable thin functionality? Does anyone figured that out?
Install sven fuchs's i18n library from http://github.com/svenfuchs/i18n
Then, in your environment.rb :
require "i18n/backend/fallbacks"
I18n::Backend::Simple.send(:include, I18n::Backend::Fallbacks)
using :"en-US" as a default locale:
I18n.default_locale = :"en-US"
I18n.fallbacks[:ca] # => [:ca, :"en-US", :en]
I18n.fallbacks :dk => [:"se-FI", :"fi-FI"] # => [:dk, :"se-FI", :se, :"fi-FI", :fi, :"en-US", :en]
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.
This worked for me (i18n gem version 0.4x didn't work).
# config/environment.rb
config.gem 'i18n', :version => '0.3.7'
# config/initializers/i18n.rb
I18n::Backend::Simple.send(:include, I18n::Backend::Fallbacks)
