CachedKeyValueStore

Sending redis a request for each of those thousands of translations scattered throughout your app is slow. This gem memoizes those requests, and sets up a simple mechanism to bust the cache.

If you want to use Redis for I18n, I recommend you watch this railscast, and use this backend instead of the KeyValue one that he uses.

Add this line to your application's Gemfile:

gem 'cached_key_value_store'

And then execute:

$ bundle

Or install it yourself as:

$ gem install cached_key_value_store

In your initializer:

I18n.backend = I18n::Backend::CachedKeyValueStore.new($redis)

The #ensure_freshness! method can be called periodically to make sure that new changes show up. I put mine in a before filter:

class ApplicationController < ActionController::Base
  before_filter :ensure_fresh_i18n

  private
  def ensure_fresh_i18n
    I18n.backend.ensure_freshness! I18n.locale
  end
end

You can also call #update_version!(locale) yourself to signal that the translations have been modified.

The on_update_version hook will be triggered every time the version is updated.
