ruby on rails - Changing Route from "/:id/model" to "/model" -

ruby on rails - Changing Route from "/:id/model" to "/model" -

i want alter path root/carts/56 root/cart.

i applied logic question rails route username instead of id, changes id of user username in path. works because username can set unique.

i want /cart lead (obviously) 1 cart visiter (no users) working , rid of :cart/:id. do not utilize user model, otherwise @user.cart (:user/cart)

so (understandably so) error

invalid route name, in use: 'cart'

because line

match '/:carts/:id' => 'carts#show', :as =>'cart', :via => :get

relevant routes:

carts /carts(.:format) carts#index post /carts(.:format) carts#create new_cart /carts/new(.:format) carts#new edit_cart /carts/:id/edit(.:format) carts#edit cart /carts/:id(.:format) carts#show patch /carts/:id(.:format) carts#update set /carts/:id(.:format) carts#update delete /carts/:id(.:format) carts#destroy

update:

with resource :cart, :only => :show # note 'resource' not 'resources' improvement, can remove id path somehow?

http://localhost:3000/cart?id=52

is gives me.

sorry - line gives me id in url is

<li><%= link_to "cart", cart_path(id: session[:cart_id]) %></li>

is singular resource need? creating carts in session this

<% if session[:cart_id] == nil %> <li><%= link_to "cart", new_cart_path %></li> <% else %>

the thought there beingness if haven't created cart yet, create 1 when visit page.

i followed tutorial carts here

in routes file use

resource :cart, :only => :show # note 'resource' not 'resources'

this give cart_path can call. nail show method in carts_controller. if need /root/ theres few ways add together that.

put above user path that's declared in routes.rb file.

you may need validation ensure users don't select names reserved.
