load_missing_constant

I have a model 'site' defined in a sub-folder 'cms' class Cms::Site < ActiveRecord::Base .....

the model is loaded correctly , checked in console: application.rb     config.autoload_paths += Dir["#{config.root}/app/models/**/"]

console

Cms::Site.all =>

Now trying to access this model from a sites_controller ( in backoffice/cms subfolder, action: index ) I get the load_missing_constant error, aslking for the model to define Site and not Cms::Site... where am I wrong ? or did I missed any initializing parameter ?

backoffice/cms/sites_controller.rb class Backoffice::Cms::SitesController < ApplicationController   def index   @sites = Cms::Site.all   end

LoadError in Backoffice::Cms::SitesController#index Expected /Users/..../app/models/cms/site.rb to define Site (activesupport (3.2.8) lib/active_support/dependencies.rb:503:in `load_missing_constant')

should it not be related to the nested namespace :backoffice :cms ? I'll try to change it
