I can't add my groceries Item to the array. I got this error message :
Shoppinglist.rb:30:in `<top (required)>': undefined method `add_list_item' for main:Object (NoMethodError)
from -e:1:in `load'
from -e:1:in `<main>'
class Shoppinglist
def create_list
print "What is the list name? "
name = gets.chomp
hash = {"name" => name , "items" => Array.new }
return hash
end
def add_list_item
print "What is the item called? "
item_name = gets.chomp
print "How much ? "
quantity = gets.chomp.to_i
hash = { "name" => item_name , "quantity" => quantity}
return hash
end
end
shopping = Shoppinglist.new
list = shopping.create_list()
puts "My List :" + list.inspect
#puts "My Shopping List " + shopping.add_list_item.inspect
list['items'].push(add_list_item())
puts "My hash : " + list.inspect
Many thanks in advance.
Regards, Thomas

# Change
list['items'].push(add_list_item())
# To
list['items'].push(shopping.add_list_item())
