Question

I set the locale for every user in the User table. I followed these instructions to fetch the locale after the user logs in. It works until the user reloads the browser, then the standard locale (en) becomes active again. How can I keep the value of user.locale in the session? I’m using Rails_Admin, which means whilst I do have a User model, I don’t have controller for the User model.

 # ApplicationController
 def after_sign_in_path_for(resource_or_scope)
  if resource_or_scope.is_a?(User) && resource_or_scope.locale !=  I18n.locale
    I18n.locale = resource_or_scope.locale
  end
  super
end

While putting it in the session is a valid answer, you can use the current_user method to get the user’s locale (and keep your session a tad cleaner)

class ApplicationController < ActionController::Base
  protect_from_forgery
  before_filter :set_locale # get locale directly from the user model

  def set_locale
    I18n.locale = user_signed_in? ? current_user.locale.to_sym : I18n.default_locale
  end
end
