Rails 3命名空间模型和控制器路由问题

Question

I have namespaced model Equipment::Feature and namespaced controller in my admin part Admin::Equipment::FeaturesController . Model is generic and is used as from within :admin namespace and for public website. I've set up the routing for :admin and :equipment namespaces

namespace :admin do
  namespace :equipment do
    resources :features
  end
end

Which gives me following routes:

 admin_equipment_features     GET /admin/equipment/features(.:format)          admin/equipment/features#index
                              POST /admin/equipment/features(.:format)         admin/equipment/features#create
 new_admin_equipment_feature  GET /admin/equipment/features/new(.:format)      admin/equipment/features#new
 edit_admin_equipment_feature GET /admin/equipment/features/:id/edit(.:format) admin/equipment/features#edit
 admin_equipment_feature      GET /admin/equipment/features/:id(.:format)      admin/equipment/features#show
                              PUT /admin/equipment/features/:id(.:format)      admin/equipment/features#update
                              DELETE /admin/equipment/features/:id(.:format)   admin/equipment/features#destroy

Pretty standard stuff. But when I address /admin/equipment/features it throws uninitialized constant Admin::Equipment::FeaturesController::Equipment exception

#index action in my Admin::Equipment::FeaturesController looks like

def index
  @features = Equipment::Feature.all
end

It did seem to work, until I declared Admin::Equipment namespace. Before it was like Admin::EquipmentFeaturesController

I guess this is some sort of namespace collision, but I don't get it - where does it come from?

Thanks in advance!

UPDATE Feature model (uses STI pattern)

class Equipment::Feature < ActiveRecord::Base

  attr_accessible :category_id, :name_en, :name_ru, :type

  belongs_to :category, :class_name => 'Equipment::Category'

  has_many :item_features, :class_name => 'Equipment::ItemFeature'
  has_many :items, :through => :item_features

  translates :name
end

class FeatureBoolean < Equipment::Feature

end

class FeatureNumeric < Equipment::Feature

end

class FeatureString < Equipment::Feature

end

class FeatureRange < Equipment::Feature

end

UPDATE2 Fixing #index action as per answer below resolved the issue. New code:

def index
  @features = ::Equipment::Feature.all
end

Answer 1

I think it's now looking for Feature in Admin::Equipment , rather than in ::Equipment

Try specifying that there is no namespace, ie

def index
  @features = ::Equipment::Feature.all
end

Answer 2

Please create folder like this app/controllers/admin/equipment/features.rb

And then edit your controller name to Admin::Equipment::FeaturesController

class Admin::Equipment::FeaturesController < ActiveRecord::Base

end
