I18n::MissingTranslationData: translation missing: en.faker error when seeding db

Question

I want to seed the database with Faker, the problem is that I am getting an error when I do a:

rake db:reset

I get this message:

rake aborted!

I don't know why is that error appearing, since I haven't got any problems with Faker before, I just wanted to reset the db to update the seeds.

I google it but I can't find anything related that solves the problem.

I tried to add:

I18n.reload!

After require 'faker' in my seeds.rb file, but no luck.

Looks like the problem is with Faker itself, because the database is being created properly, when I do a rake db:drop db:create db:migrate it works, until there, but when I try to seed the database with Faker with rake db:seed or rake db:reset, I get the error.

What can I do? Thanks in advance.

UPDATE - I included seeds.rb and en.yml files

seeds.rb:

require 'faker'

# Create Users
5.times do
  user = User.new(
    name: Faker::Name.name,
    email: Faker::Internet.email,
    password: Faker::Lorem.characters(10)
  )
  user.skip_confirmation!
  user.save!
end
users = User.all

# Create Wikis
25.times do
  Wiki.create!(
    title: Faker::Lorem.sentence,
    body: Faker::Lorem.paragraph,
    :private => false,
    user: users.sample
  )
end

# Create Admin account
admin = User.new(
  name: 'Admin User',
  email: '[email protected]',
  password: 'helloworld',
  role: 'admin'
  )
admin.skip_confirmation!
admin.save!

# Create Premium account
premium = User.new(
  name: 'Premium User',
  email: '[email protected]',
  password: 'helloworld',
  role: 'premium'
  )
premium.skip_confirmation!
premium.save!

# Create Standard account
standard = User.new(
  name: 'Standard User',
  email: '[email protected]',
  password: 'helloworld',
  role: 'standard'
  )
standard.skip_confirmation!
standard.save!

puts "Seed finished"
puts "#{Wiki.count} wikis created"
puts "#{User.count} users created"

en.yml:

en:
  hello: "Hello world"

Answer 1

In my case, the I18n available_locales config did not include en:

config.i18n.available_locales = %i[de de_en]

I reverted it back to

config.i18n.available_locales = %i[de en]

and it worked.

Check the I18n Faker configuration info here:

https://github.com/stympy/faker#customization

Looks like you should enforce the I18n Faker locale in case you are using a non standard locale in your app.

Just set Faker::Config.locale to the locale you want, and Faker will take care of the rest.
