Faker: Faker::Lorem.paragraph raises I18n::MissingTranslationData without manual locale override

[rmm5t]

I18n::MissingTranslationData: translation missing: en.faker.lorem.words

This was introduced in v1.4.0 and is still a problem in v1.4.3. If I manually set the local to "en," it works as expected, but prior to v1.4.0, manually setting the locale wasn't necessary (tested with v1.2.0 and v1.3.0).

UPDATE: I was wrong about the locale override working. This appears to exhibit itself only when Faker is used inside an ERB file and when that ERB file is loaded from a rake file.

[drewish]

I'm getting it when using faker from FactoryGirl factories, but those are driven by rake tasks.

[drewish]

Actually doesn't seem like rake has anything to do with it:

Anyone have ideas on a workaround? Getting this issue from rake and from the console, and for many methods, not just words:

± bin/rails c
Loading development environment (Rails 4.1.8)
[1] pry(main)> require 'faker'
=> true
[2] pry(main)> Faker::Lorem.words(2)
I18n::MissingTranslationData: translation missing: en.faker.lorem.words
from /Users/thom/.rbenv/versions/2.1.3/lib/ruby/gems/2.1.0/gems/i18n-0.6.11/lib/i18n.rb:314:in `handle_exception'
[3] pry(main)> Faker::Company.name
I18n::MissingTranslationData: translation missing: en.faker.company.name

[4] pry(main)> Faker::VERSION
=> "1.4.3"
...

Calling Faker::Config.locale = 'en' doesn't seem to make any difference.

EDIT Found workaround: add I18n.reload! sometime after you first require 'faker' in your environment. Source: this super-old issue

[drewish]

yeah the I18n.reload! got it working for me too.

[StyleOffDev]

Still an issue :disappointed: We're using faker (1.4.3) and rails (= 4.2.0)

[fuzzyalej]

:-1: Still an issue w/ 1.4.3 & 4.2.0

[lessless]

same here with 1.5.0 and 4.2.4

[swapnilchincholkar]

Seems its working, check following

Loading test environment (Rails 4.2.4)
2.2.0 :001 > require 'faker'
 => false 
2.2.0 :002 > Faker::Lorem.words(2)
 => ["magni", "facere"] 
2.2.0 :003 > Faker::Company.name
 => "Gleason, Stanton and McKenzie" 
2.2.0 :004 > Faker::VERSION
 => "1.6.3" 

[coorasse]

require 'faker'
I18n.reload!

fixed for me as well

[dunyakirkali]

Still an issue with 1.6.3 and rails 3.2.22.1

[krisleech]

Still an issue with 1.6.5 and rails 4.2.7

[swapnilchincholkar]

Still doesn't seems an issue

Loading test environment (Rails 4.2.7)
2.2.0 :001 > Faker::VERSION
 => "1.6.5" 
2.2.0 :002 > Faker::Lorem.words(2)
 => ["cumque", "et"] 
2.2.0 :003 > Faker::Company.name
 => "Kuhn-Lakin" 

@krisleech could you provide any more info to debug

[deivid-rodriguez]

@swapnilchincholkar I think you can reproduce this by specifying gem 'faker', require: false in your Gemfile, and then manually requiring faker right before usage.

[thisismydesign]

This is still an issue for me on 1.9.1 using Faker::Beer.brand. None of the above workarounds worked.

[vbrazo]

@thisismydesign which ruby version were you using? Could you provide a sample application that reproduces the bug?

[thisismydesign]

ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-linux]

[mvdamme]

Same for me, I get this error with 1.9.1 using Faker::Educator.degree.

Hello we 're having the same problem with this setup:
rails 3.2.22.2, ruby 2.3.7, faker 1.9.1
In the Gemfile i tried gem 'faker' with and without require: false
Our default locale is :de. In config/environments/test.rb i specified config.i18n.default_locale = :en.
The setting of Faker::Config.locale = :fr in spec_helper.rb is ignored.

How can i tell Faker to not try to translate the phrases?

[jeremygachet]

I juste never call require 'faker' directly in rails.
Where should I add the I18n.reload! to make it work with Rspec ?

[coorasse]

I placed it in

config.before :suite do
  I18n.reload!
end

[alexives]

Using I18n.reload! doesn't seem to fix it for me with rails 5.5.2, faker 1.9.3, rspec-core 3.8.0, and ruby 2.5.1

[comerio]

I tried all the ways without any success with rails (5.2.2), faker (1.9.3) and ruby 2.5.0.
Despite I configure Faker::Config.locale in a faker.rb, on every try the Faker tries to load en.yml.

I18n::MissingTranslationData (translation missing: en.faker.name.title)

[vbrazo]

@DaKaZ Faker doesn't provide Faker::Name.title anymore. It was deprecated last year and removed recently. Please use Faker::Job: https://github.com/stympy/faker/blob/master/doc/default/job.md.

[DaKaZ]

@vbrazo ahhh, sorry, stupid user error ;) I didn't even think to check that the API had changed. Thanks

[rojosinalma]

Any solutions to this 5 year old problem?

I tried I18n.reload! without success
Faker::Config.locale also did nothing for me

[Ex-Ark]

I am having the I18n::MissingTranslationData (translation missing: en.faker) in my test suite as well.

I run with RSpec.config.order = :random and sometimes the tests all pass, and sometimes they all fail due to faker running into missing translation error.
If I run with no random order, then I encounter no errors.

I isolated multiple seeds in which the tests all fail. I have no idea if this could be a lead onto something. (38629 , 56820 )
I'm just going to disable the random order for now, but I'm eager to see this bug resolved as it is not a viable solution.

Also depending if I run my test suite with bundle exec rspec or rspec I have differents outputs (all fail => all pass).

In conclusion I believe it's just related to the order in which the files are required, as I have a default case in which everything works fine.

My env:

Rails.config.action_view.raise_on_missing_translations = false
I18n.config.available_locales = :fr
I18n.config.default_locale = :fr
Faker::Config.locale = 'fr'

@stympy ping

[stympy]

It would be helpful if someone could provide a sample app and info on the environment that can reliably reproduce this error.

[Ex-Ark]

After some experimenting, I found for my case that it was the enforce_available_locale that was causing this.

I have only one available locale set in my rails app (:fr), so when Faker fallback to :en locale then it raises MissingTranslation because :en locale was not loaded in a first place :

When faker load its locales, the enforce available locale is defaulted to true by Rails if not set, and so the :en locale file is skipped, raising later a MissingTranslation error in case the fallback to :en is needed.

Here is how I18n filter the given .yml in load_paths :

def store_translations(locale, data, options = EMPTY_HASH)
          if I18n.enforce_available_locales &&
            I18n.available_locales_initialized? &&
            !I18n.available_locales.include?(locale.to_sym) &&
            !I18n.available_locales.include?(locale.to_s)
            return data
          end
          locale = locale.to_sym
          translations[locale] ||= {}
          data = data.deep_symbolize_keys
          translations[locale].deep_merge!(data)
end

Notice how if enforce_available_locale is true then the .yml locale must be specified in available_locales in order to be loaded.

Maybe Faker could force load the :en yml locale files into I18n, because it is needed internally by Faker, even if the whole Rails app doesnt need english at all.
This can handle the case where the fallback to :en locale is needed , but the Rails env has no :en in available locale and enforce is true by default.

I noticed Faker already plays with enforce_available_locale so it could be used as well when loading the locales :

I18n.load_path += Dir[File.join(mydir, 'locales', '**/*.yml')]
I18n.reload! if I18n.backend.initialized?

To fix it in the Rails app, I manually set up config.i18n.enforce_available_locales = false in my config\environments\test.rb so when Faker loads the locales, nothing is skipped.

Other solution could be to add :en to available_locale for the test env, before Faker is loading yml locales.

[bjnord]

Note the answer from @vbrazo above: The right solution to this error is to change Faker::Name.title to Faker::Job.title in your code.

But if you just want to make the error go away, and I18n.reload! isn't working for you, you can add the missing translation to your config/locales/en.yml (or other locale) file:

en:
  faker:
    name:
      title: 'Title'

[weston-vericatch]

Warning: This error will also occur if you accidentally use .uniq instead of .unique.

Do you think we could possibly add this as an alias?

[Piioo]

I have this problem with locale de for de.faker.lorem.punctuation.space.

This happen, because faker do not have translations for this key in de locale and I do not load the en locale as fallback

or you use the fallback, but then you need to define all fallbacks:

require 'i18n/backend/fallbacks'
I18n::Backend::Simple.send(:include, I18n::Backend::Fallbacks)

I18n.fallbacks = { de: [:de, :en], en: [:en] }
