Question

In my rails app i have such route for carts controller:

resources :carts

so in layout, according to my logic i have:

= link_to "Моя корзина", @cart

and in browser i see for example:

******:3000/carts/112

Could i however do nested rails route show as post-like request? so i will have:

******:3000/carts/

also rake routes:

arts GET    /carts(.:format)                                                          carts#index
                                  POST   /carts(.:format)                                                          carts#create
                         new_cart GET    /carts/new(.:format)                                                      carts#new
                        edit_cart GET    /carts/:id/edit(.:format)                                                 carts#edit
                             cart GET    /carts/:id(.:format)                                                      carts#show
                                  PUT    /carts/:id(.:format)                                                      carts#update
                                  DELETE /carts/:id(.:format)                                                      carts#destroy
                             cart POST   /carts/:id(.:format)                                                      carts#show

I now how to write it for my own methods… But how to be with build-in show?

i need to change show route, so that id for show is sending not as get-param by url, but as post-param in request…

The resources method simply puts in a bunch of predefined routes, as described here.

Specifically, it is adding the equivalent of

get '/carts/:id' => 'carts_controller#show'
post '/carts' => 'carts_controller#create'
...

If you want to use a different set of routes, don’t use resources, and just define your own routes instead.

Also, you can’t hide the cart id from the user this way. If the request contains the ID, it means that the user can see it. He might have to view it with Firebug or by looking at the page source instead of his address bar, but it’s still not secret or protected in any way.
