Why are not displayed string?

I created method "to_s" :

  def to_s
    "#{self.name}:#{self.price}:#{self.weight}"
  end

When I add products to the cart by "cart.add_item"

@items = []
@items << AntiqueItem.new({:price => 111, :weight => 100, :name => 'car'})
@items << RealItem.new({:price => 111, :weight => 100, :name => 'kettle'})
@items << RealItem.new({:price => 200, :weight => 100, :name => 'dishwasher'})

cart = Cart.new('vitalik')

cart.add_item RealItem.new({:price => 111, :weight => 100, :name => 'car'})
cart.add_item RealItem.new({:price => 121, :weight => 100, :name => 'car'})
cart.add_item RealItem.new({:price => 151, :weight => 100, :name => 'kettle'})

p cart

In the console information is not displayed string

E:\work\storeapp3\app\storeapp\shop>ruby init.rb
#<Cart:0x2685888 @items=[#<RealItem:0x2685828 @weight=100, @real_price=111, @name="car">, #<RealItem:0x2685738 @weight=100, @real_price=121, @name="car">, #<RealItem:0x2685648 @wei
ght=100, @real_price=151, @name="kettle">], @owner="vitalik">

Maybe I made a mistake somewhere?

It's because p displays the result of calling inspect method on object. You can use puts instead.
