Hello folks,

I have a problem with nested namespaces route and can’t figure what to  
do. (I hate this clouse 🙂 )

Let’s say I have (for better understanding)  
posts =\> inv\_ocenas  
comments =\> inv\_ocena\_posts

I am in the form for editing inv\_ocena. At the bottom I have table  
with all correspondig inv\_ocena\_posts.  
When I try to add new inv\_ocena\_posts, the correct url is generated  
(“[http://localhost:3000/admin/inv\_ocenas/2/inv\_ocena\_posts/new](http://localhost:3000/admin/inv_ocenas/2/inv_ocena_posts/new)”), but  
the form for adding new “inv\_ocena\_posts” is not opened. I get error  
“NoMethodError in Admin/inv\_ocena\_posts#new”.

As I can see, the problem is in wrong generated path for add-ing new  
inv\_ocena\_posts “admin\_inv\_ocena\_admin\_inv\_ocena\_posts\_path” ← admin  
is present 2 times in path!!  
It should generate “admin\_inv\_ocena\_inv\_ocena\_posts\_path”

By the book it should work …  
[http://api.rubyonrails.org/classes/ActionController/Routing/RouteSet/Mapper.html](http://api.rubyonrails.org/classes/ActionController/Routing/RouteSet/Mapper.html)  
(It’ll also create admin\_product\_tags\_url pointing to “admin/products/  
#{product\_id}/tags”, which will look for Admin::TagsController.)

I google a lot, but can’t find what I am missing here … please  
help 😉
