Rails - Sep 2006 - possible bug: edge rails, nested resources and images

Im trying to show images in my restful application and have finally 
found what appears to be the source of the problem.

When i have the products resource nested in categories as showen below 
in the first routes file i can see the categories index (/categories).

When i add the images to the products resource map as shown in routes 2 
i get the error:

image_url failed to generate from {:controller=>"images", 
:action=>"show", :category_id=>"rails"}

It appears that the image_tag is being confused for an image_url ???

Has anyone come across this or have the acts_as_attachment plugin 
working in their application.




1. routes.rb (working version1) ========================#eg
categories/1/products

  map.resources :categories do |categories|
    categories.resources :products
  end

  map.connect '':controller/service.wsdl'', :action =>
''wsdl''
  map.connect '':controller/:action/:id''


2. routes.rb (not working version2)============================#eg
categories/1/products/1/images

  map.resources :categories do |categories|
    categories.resources :products do |products|
      products.resources :images
    end
  end

  map.connect '':controller/service.wsdl'', :action =>
''wsdl''
  map.connect '':controller/:action/:id''


view/index=============================<%= image_tag
''rails'' %>


error =================================ActionController::RoutingError in
Categories#index
Showing app/views/categories/index.rhtml where line #20 raised:

image_url failed to generate from {:controller=>"images", 
:action=>"show", :category_id=>"rails"}, expected: 
{:controller=>"images", :action=>"show"}, diff:
{:category_id=>"rails"}

I just changed the nested loop to look like this:


 #resource mappings
  map.resources :categories do |categories|
    categories.resources :products do |products|
      products.resources :parts
    end
  end

This now works. Parts is inherited from images.

So, it looks like you can''t have a resource called images! As this will
cause the image_tag to be read as image_url.

It would be good to get someones opinion on this, jsut in case im waaay 
of base.
