Rails 5: How do I reference I18n translations from another yaml config file?

I have a config file:

# config/meta.yml
base_meta:
  title: 'Top 10 Cats'

It has an corresponding initializer:

# config/initializers/meta.rb
META = YAML.load_file("#{Rails.root.to_s}/config/meta.yml")

I can access the title like so:

META['base_meta']['title'] #=> "Top 10 Cats"

However, I want to internationalize my meta data. I believe this should be handled by the existing locales/ yaml files.

How do I reference the existing translation?

# config/locales/en.yml
en:
  title: 'Top 10 Cats'

I've tried using erb, but it doesn't work:

# config/meta.yml
base_meta:
  title: t(:title)

Renaming the file to config/meta.yml.erb has no effect either.

Is there a way to reference the I18n keys from my config file?

Instead of its value, you could add the key for the existing translation in your YAML file:

# config/locales/en.yml
en:
  cats:
    title: 'Top 10 Cats'

# config/locales/de.yml
de:
  cats:
    title: 'Top 10 Katzen'

# config/meta.yml
base_meta:
  title: 'cats.title'

So it just returns that key:

META['base_meta']['title'] #=> "cats.title"

Which can then be passed to I18n.t:

I18n.locale = :en

t(META['base_meta']['title']) #=> "Top 10 Cats"

I18n.locale = :de

t(META['base_meta']['title']) #=> "Top 10 Katzen"

Try replace in application.rb default value of config.i18n.load_path parameter with that:

config.i18n.load_path += Dir[Rails.root.join('config/locales/**/*.yml').to_s]

It works for me.
