I am trying to write a nested route ‘new style’

map.resources :franchises, :has\_many =\> :documents

in place of the :

map.resources :franchises do |franchises|  
franchises.resources :documents, :name\_prefix =\> “franchise\_”  
end

but get an error :  
no route found to match “/franchises/1/documents” with {:method=\>:get}

running rake routes, cannot see it…  
what could be the problem with my Rail install ?

thanks

Shouldn’t ‘franchise’ be singular when used with an id?

I tried it too…  
no route found to match “/franchise/1/documents” with {:method=\>:get}

a rake routes doesn’t show up any nested route for documents, it seems  
the :has\_many is not seen at all

Are you running edge Rails? If not, :has\_many won’t work.

I’ve put your map.resources line in my routes.rb, and I get this in  
the console:

> > r = ActionController::Routing::Routes  
> > =\> # lots of output…  
> > r.recognize\_path(“/franchises/1/documents”, :method =\> :get)  
> > =\> {:controller=\>“documents”, :action=\>“index”, :franchise\_id=\>“1”}

This is on revision 7340 (a fairly recent edge Rails).

David,  
I am trying to figure out if this is the intended behaviour  
map.resources :users,  
:has\_many =\> [:groups]

map.resources :groups, :collection =\> {:joined =\> :get, :created =\>  
:get}

in console I type

> > r = ActionController::Routing::Routes  
> > r.recognize\_path("/groups/created", :method =\> :get)  
> > =\> {:controller=\>“groups”, :action=\>“created”}

> > r.recognize\_path("/users/diego/groups/created", :method =\> :get)  
> > =\> {:controller=\>“groups”, :user\_id=\>“diego”, :action=\>“show”,  
> > :id=\>“created”}

the collections routes for groups are not carried over into the nested  
version inside of user.  
Furthermore there is no syntax like has\_many =\> [:posts =\>  
{:collections =\> {:joined =\> :get} } ] in place.

I am guessing that my only options is to repeat any :new, :member or  
:collections specific routes.

Am I guessing right?
