I am a beginner Ruby on rails, I am trying to create a small system of cart. I already rather advance well thanks to stackoverflox and some little tutorial on the web. The problem is that I can not empty my cart without error, I would have to create an action that removes the cookie from my application but I can not. Here is the source of my app that works but without the possibility to empty are basket
view/cart/index.html.erb
> <h1>Votre panier</h1>
> <!DOCTYPE html>
> <html>
> <head>
> <title></title>
> </head>
> <body>
>
> <% total = 0 %>
>
> <table>
> <% @cart.each do |id, quantity| %>
> <% item = Item.find(id) %>
> <tr>
> <td class="images"><%= link_to image_tag(item.image_url, :size => "50x50"), item %></td>
> <td width="160"><%= item.produit %></td>
> <td width="160"><%= quantity %></td>
> <td width="160"><%= number_to_currency(item.prix, unit: "€") %></td>
> </tr>
> <% total += quantity * item.prix %>
>
> <% end %>
>
> <tr>
> <td colspan="4">Total :</td>
> <td><%= number_to_currency(total, unit: "€") %></td>
> </tr>
>
> </table>
>
> # Please, i want empty my cart !
> <%= link_to 'Back', items_path %>
>
> </body>
> </html>
cart_controller.rb
class CartController < ApplicationController
def index
@cart = session[:cart] || {}
end
def add
id = params[:id]
cart = session[:cart] ||= {}
cart[id] = (cart[id] || 0) + 1
redirect_to :action => :index
end
end
routes.rb
Rails.application.routes.draw do
resources :items
get 'cart/index'
match ':controller/:action/:id', via: [:get, :post]
root :to => "items#index"
end
