How to display multiple items using puts?

Question

I have written a Travel App with Tour Items and I'm trying to display the order at the end.

When I use puts @order_items I get {"SevendaySurfSportTour"=>2} for two tours.

I would like it to display 2 SevendaySurfSportTour at the end. But I don't know how, any help would be good?

class TourOrder
    def initialize
        @order_items = Hash.new(0)
    end
    def add_item(name, quantity)
        @order_items[name] += quantity
    end
    def get_items
        return @order_items
    end

    def display
        puts "Thank you for coming!"
        puts @order_items
    end
end

@order_items is a hash and what has printed out if the string representation of such a hash. When you want to format the output differently, then you have to implement that on your own – for example like this:

def display
  puts "Thank you for coming!"

  @order_items.each do |name, quantity|
    puts "#{quantity} #{name}"
  end
end

Below code works for you

class TourOrder
  def initialize
    @order_items = Hash.new(0)
  end
 
  def add_item(name, quantity)
    @order_items[name] += quantity
  end
 
  def get_items
    @order_items
  end

  def display
    puts "Thank you for coming!"
    puts items 
  end

  def items
    @order_items.collect{ |k, v| "#{v} #{k}"}
  end
end

t = TourOrder.new
t.add_item('SevendaySurfSportTour', 2)
t.add_item('Foo', 4)
t.add_item('Bar', 1)
t.display
=> Thank you for coming!
   2 SevendaySurfSportTour
   4 Foo
   1 Bar
