Ruby on Rails

undefined local variable or method `cart'

undefined local variable or method `card'

What is the url you're using to show this on a separate page ? 

if its in the pattern of "/cards/:id/something" then you dont have to provide the card path as rails picks up @card object to build the path or you'll have to pass the card variable inside the path method. 

eg

<% @cards.each do |card| %>

  <li><%= link_to '<i class="fa fa-money"></i> Card'.html_safe, cart_path(card) %> </li>

<% end %>

This way, rails would know "which" exact card this link should take them to.

Hello,

I follow the Agile Web development book.

Now as a extra challenge I try to make the card visible on a seperate page.

So I made this link :

<li><%= link_to '<i class="fa fa-money"></i> Card'.html_safe, cart_path %> </li>

But now I see the above error message.

When I do card_path (:id) I see a message that there is no card with the id of id.
