Hi!

I am trying to get this to work: it is really close and half way  
works.

routes:

map.namespace(:admin) do |admin|  
admin.namespace(:products) do |products|  
products.resources :brains,  
:has\_many =\>  
[:pdfs, :images, :firmwares, :specables]  
end  
end

when I run rake routes i get stuff like:

new\_admin\_products\_brain  
edit\_admin\_products\_brain

which is what I expected. however when I try to use this in a form  
like such:

\<% form\_for([:admin, @product]) do |f| %\>

I get an error this error from rails in a from view:

undefined method `admin\_product\_brain\_path’ for #\<ActionView::Base:  
0x20350f0\>

Not sure how to fix this, but this is so freggin close it is  
painful…

Anyone know the answer?

Happy New Year!

BTW,

My controller looks like this:

class Admin::Products::BrainsController \< Admin::ProductsController  
end

as these are all just products…  
Hope this makes sense.
