Setting default_url_options for mounted Rails engine

Question

Using rails 3.2.13 and spree 2.0.2
I\'ve encountered the similar problem as in Rails mountable engine under a dynamic scope

My routes:

scope \':l

Faced exactly the same problem and I have found a solution for that...

Here is my application_controller-File (my engines inherit from this file (which is the Main Apps ApplicationController, so that I don't have code-duplication)

#!/bin/env ruby
# encoding: utf-8
class ApplicationController < ActionController::Base
  # Prevent CSRF attacks by raising an exception.
  # For APIs, you may want to use :null_session instead.
  protect_from_forgery with: :exception

  before_filter :set_locale_from_params

  def url_options
    { locale: I18n.locale }
  end

  protected
    def set_locale_from_params
      if params[:locale]
        if I18n.available_locales.include?(params[:locale].to_sym)
          I18n.locale = params[:locale]
        else
          flash.now[:notice] = 'Translation not available'
          logger.error flash.now[:notice]
        end
      end
    end
end

Note, that the url_options-code is outside the protected part. It has to be public.

Found the tipps for the solution here: default_url_options and rails 3

Hope it helps
