Rails routing with subfolders

Question

I have such structure of my view folders (they display logis structure):

so i have subfolder in admin subfolder, that in catalogs folder i have to subfolder, manufacturer etc (manufacturer and other have there controller's with views, only catalogs and to are empty)

and rails automatically generated me such routes:

 namespace :admin do
   namespace :catalogs do
     namespace :to do
       namespace :manufacturers do
         namespace :models do
           namespace :types do
             resources :articles
           end
         end
       end
     end
   end
 end

 namespace :admin do
   namespace :catalogs do
     namespace :to do
       namespace :manufacturers do
         namespace :models do
           resources :types
         end
       end
     end
   end
 end

 namespace :admin do
   namespace :catalogs do
     namespace :to do
       namespace :manufacturers do
         resources :models
       end
     end
   end
 end

 namespace :admin do
   namespace :catalogs do
     namespace :to do
       resources :manufacturers
     end
   end
 end

manufacturers, models, types work normally, but articles work strange... When i try to write such form partial:

= form_for [:admin, :catalogs, :to, :manufacturers, :models, :types, @art] do |f|
  = f.label "OEM"
  = f.text_field :oem_number
  = f.label "Бренд"
  = f.text_field :manufacturer
  = f.label "Название"
  = f.text_area :name
  = f.label "Кол-во"
  = f.text_field :quantity
  = f.label "Комментарий"
  = f.text_area :details
  = f.label "Только с VIN"
  = f.check_box :only_with_vin
  = f.hidden_field :type_id, @type_id
  .form-actions
    = f.submit 'Сохранить изменения', :class => "btn btn-primary"

something is bad, i get undefined method `admin_catalogs_to_manufacturers_models_types_to_articles_path' for #<#:0xbbedf60>

but for example in types i have such form:

= form_for [:admin, :catalogs, :to, :manufacturers, :models, @man] do |f|  
  %b
    = @man.Name
  %br
  = @man.TYP_PCON_START.to_s[4...6].concat("-").concat(@man.TYP_PCON_START.to_s[0...4])
  \-  
  -if @man.TYP_PCON_END.blank?
    = "наст. время"
  -else
    = @man.TYP_PCON_END.to_s[4...6].concat("-").concat(@man.TYP_PCON_END.to_s[0...4])
  %br
  = ((@man.TYP_HP_FROM.to_f*0.74).round).to_i
  kW
  = f.label "Отображать в списке ТО?"
  = f.check_box :is_in_to
  .form-actions
    = f.submit 'Сохранить', :class => "btn btn-danger"
    = link_to 'Назад', :back, :class => "btn"

and all is ok, what's wrong with articles? How and what to change in my route and optimize it? I try a little bit, but get errors...

If you wish to hold on to this nested structure, i think it is best to use nested resources instead of namespaces.

Nested resources would look like:

namespace :admin do 
  resources :catalogs do 
    resources :to do 
      resources :manufacturers do 
        resources :models do 
          resources :types do 
            resources :articles do 

A form for articles would look like: form_for [:admin, @catalogue, @to, @manufacturer, @model, @type, @article] A url for the index of afticles would look like admin_catalogs_to_manufacturers_models_types_articles_path(@catalogue, @to, @manufacturer, @model, @type) and would generate a url like: www.example.com/admin/catalogs/1/to/1/manufacturer/1/model/1/type/1/articles

Note that all the parts of a url are actually instances except for admin
