routes - Rails routing multiple controller -

I am trying to create a admin controller which requires access to many other resource models is. / P>

For example

A : shelf controller : books , : movies and : Music .

Now I want to root it so I have tried it earlier: localhost: 3000 / shelf / books / new

  Resources: Books ,: Shelf => 'Books'   
 but they do not work.  
 At this time someone's help would be appreciated.  
 Thanks   
 
 
 Try something like that  
  Resources: do shelf resources: end of books   
 then you can do something  
  Resources: do shelf resources: books resources : Movies ... End   
 This will be the path to localhost: 3000 / shelf / books  Hope it helps!  
  Update  If you want all book resources under one shelf, then you can use a namespace  
  Namespace: Use shelf resources: end of books
