How to set I18n.t in Rails 3.2 for individual user?

Our rails app sets the I18n.t in a file under config/initializers:

I18n.default_locale = 'EN' if Rails.env.production?

This line of code is executed before a user logs in. We would like to set the I18n.t environment based on individual user after she/he logs in. Is there a way doing this individual user based I18n.t?

Solution

  • The the I18n.locale in a before_filter in your application_controller after you identified the current_user. 

    before_filter :set_locale

private
def set_locale
  I18n.locale = current_user.preferred_locale if current_user
end

    Note: You might need to change current_user and preferred_locale to match the naming of these instances and attributes in your application.

    See Rails guides about setting and passing the locale.
