Helper module not included on subsequent requests form engine gem in development from passenger

Hi,

I’m working on a Rails 2.3.5 based gem that acts as an “add-on” for an
existing application. It basically pulls in functionality from
another more generic gem and sets up the application to use it.

In its rails/init.rb it adds some helpers to ApplicationHelper.
Here’s the init.rb file:

github.com

kete/kete_translatable_content/blob/master/rails/init.rb

require 'mongo_translatable'
require 'kete_translatable_content'
require 'kete_translatable_content/extensions/extended_content_translation'
require 'kete_translatable_content/extensions/translation_from_version'
require "#{Rails.root}/test/has_value.rb"

config.to_prepare do

  # In development/production, we want to only setup stuff if IS_CONFIGURED is true
  # In test mode however, we always want to have it, since IS_CONFIGURED won't be true
  # at this stage, but it will be changed to true after Rails initializes.
  if (IS_CONFIGURED || Rails.env.test?) && kete_translatable_content_ready?

    Kete.translatables.each do |name, options|
      args = [:mongo_translate, *options['translatable_attributes']]
      args << { :redefine_find => options['redefine_find'],
        :through_version => options["through_version"]}
      
      class_name = name.camelize
      klass = class_name.constantize

and here is the other gem’s lib that is being included:

github.com

kete/mongo_translatable/blob/master/lib/translatables_helper.rb

module TranslatablesHelper
  def available_in_locales_for(translatable, options = {})
    return if TranslationsHelper.available_locales.size < 2

    html = "<ul style='list-style:none; margin:0; padding:0;'>"
    html += "<li style='float:left;'>#{I18n.t('translations.helpers.available_in')}</li>"
    options[:params] ||= {}

    translated_in_locales = Array.new
    translatable.available_in_these_locales.each_with_index do |locale, index|
      styles = "float: left; padding: 0 5px; #{'border-left: 1px solid #000' unless index == 0}"
      onclick = 'update_translation_box(this); return false' if options[:lightbox]

      html += content_tag(:li, :style => styles) do
        link_to_unless_current(TranslationsHelper::available_locales[locale],
          url_for(:locale => locale, :to_locale => (params[:to_locale] if defined?(params))),
          { :onclick => onclick })
      end
      translated_in_locales << locale unless locale == translatable.original_locale
    end

My issue is that after the initial request to my app on a view that
calls one of those helpers, I get a method not defined error if I’m in
development mode (production works as expected).

I’ve tried a few different things (unloadable and wrapping method
definitions in unless modules.include? TranslatablesHelpers
conditional), but am not making any headway.

Suggestions?

Cheers,
Walter
