[Rails] Re: Associations join

I've just got a really basic setup to see if i got it working:


card.rb
class Card < ActiveRecord::Base
attr_accessible :attack, :defense, :name
has_many :cardlevels
has_many :users, :through => :cardlevels
end

cardlevel.rb
class Cardlevel < ActiveRecord::Base
attr_accessible :card_id, :level, :user_id
belongs_to :user
belongs_to :card
end

user.rb
class User < ActiveRecord::Base
attr_accessible :name
has_many :cardlevels
has_many :cards
end
-----------------------------------------------------

card_controller.rb
class CardController < ApplicationController
def show
@card = Card.all
end
end

User & cardlevel are empty for now
-----------------------------------------------------

<h1>Card#show</h1>
<p>Find me in app/views/card/show.html.erb</p>
<%= @card.user %>
Where i tried eaching the @card, tried @card.users, @card.user.name etc.
etc.
-----------------------------------------------------

The error:
Showing c:/tuts/kaartje/app/views/card/show.html.erb where line #3
raised:

Extracted source (around line #3):
