I am using Active_job and sidekiq to send emails asynchronously.
But my current_locale is lost when performing the sending.
I set the I18n.locale by the url patterns of every request.
I used to use Sidekiq, which provide a plugin to store the current_locale, and use it when sending.
But I am now upgrading to Rails 4.2.1, ActiveJob seems it doesn’t provide a solution like this.
