I18n::InvalidPluralizationData (translation data {:one=>"tenth", :other=>"tenths"}

[touch-dev-null]

Hello,

Have an issue with EN translation, please see an example:

irb(main):016:0> I18n.with_locale(:ru) { (3.75).to_words }
=> "три целых и семьдесят пять сотых"

irb(main):017:0> I18n.with_locale(:fr) { (3.75).to_words }
=> "trois et soixante-quinze centièmes"

irb(main):018:0> I18n.with_locale(:ua) { (3.75).to_words }
=> "три цiлих i сiмдесят п’ять сотих"

irb(main):019:0> I18n.with_locale(:en) { (3.75).to_words }
Traceback (most recent call last):
        2: from (irb):19
        1: from (irb):19:in `block in irb_binding'
I18n::InvalidPluralizationData (translation data {:one=>"hundredth", :other=>"hundredths"} can not be used with :count => 75. key 'many' is missing.)
irb(main):020:0>

Hi!

I haven't been able to reproduce it. Do you mind sharing your installed gem versions?:

>> I18n.with_locale(:en) { (3.75).to_words }
=> "three and seventy-five hundredths"
>> NumbersAndWords::VERSION
=> "0.11.6"
>> I18n::VERSION
=> "1.7.0"

[touch-dev-null]

The same for me:

irb(main):006:0> NumbersAndWords::VERSION
=> "0.11.6"
irb(main):007:0> I18n::VERSION
=> "1.6.0"

Also, I have found one thing - this error happened for me only in staging and production Rails environments. In development all works as expected:

Loading production environment (Rails 5.2.3)
2.6.3 :001 > Rails.env
 => "production" 
2.6.3 :002 > I18n.with_locale(:en) { (3.75).to_words }
Traceback (most recent call last):
        2: from (irb):2

2.6.3 :002 > I18n.with_locale(:en) { (3.75).to_words }
 => "three and seventy-five hundredths" 

Do you know how is it possible?

There's a difference with localization data in those environments. Try to put up a project where this is reproducible that we can play with?

[touch-dev-null]

Sorry, it is private repo, I can`t share it.

I created new clean rails app and tested it - it is working without exceptions both for prod and dev o_O

Also, in my project, it started to work without exception when I changed

config.i18n.fallbacks = true

on

config.i18n.fallbacks = false

into config/environtments/production.rb

[dblock]

That's what I am saying, you have something in your en.yml that cannot be found, while it works for other languages. Try to drop two of your .yml's into the test Rails app?

[touch-dev-null]

Interesting, I reverted config.i18n.fallbacks to the true again and cleaned up all yml files in config/locales and an exception was reproduced.

Also, I tried to disable most of gems which I am using in my app without any luck.

Will try to find the issue reason and update you.

I wonder if it is related to ruby-i18n/i18n#401
