I am able to combine purchase, however the quantity is not showing,  
any suggestions?  
Code:

class Basket

attr\_reader :purchases  
attr\_reader :total

def initialize  
@purchases = []  
@total = 0.0  
end

def add\_purchase(cart)  
@purchases \<\< Purchase.buy\_one(cart)  
@total += cart.price  
end

def add\_purchase(cart)  
appendFlag = true  
for purchase in @purchases  
if (cart.id == purchase.cart.id)  
appendFlag = false  
purchase.quantity += 1  
end  
end  
if(appendFlag)  
@purchases \<\< Purchase.buy\_one(cart)  
end  
@total += cart.price  
end

def clear  
@purchases = []  
@total = 0.0  
end

end
