rails-i18n translations seem to be not loaded

Question

Stage:

I have a Rails 3.2 application, I add to my Gemfile:

gem 'rails-i18n'

then I execute bundle install.

In a view I request a i18n message, for example:

<%= l Time.now, format: :short %>

and in config/initializers/locate.rb, I set default locate:

I18n.default_locale = :es
I18n.available_locales = :es

Problem:

I18n::MissingTranslationData in Events#index

translation missing: es.time.formats.short

What's wrong? Is rails-i18n not loaded right?

Test:

Let's add puts I18n.load_path in config/initializers/locate.rb file:

I18n.default_locale = :es I18n.available_locales = :es

puts I18n.load_path

and then restart application, asi you can see there are listed all path loaded:

Answer 1

It is available only in Rails' defaults for English - en.yml.

You have to add this lines to your es.yml:

es:

    formats:
      default: "%Y/%m/%d"
      short: "%b %d"
      long: "%B %d, %Y"
