The push method in ruby

I am having some problems with the sintaxis of this code , please tell me what i'm doing wrong. Thanks.

grocery_list = { 'title' => 'Grocery List', 'items' => [] } grocery_item = { 'title' => 'Bread', 'quantity' => 1 } grocery_list['items'].push{grocery_item}

shopping_list.rb
grocery_list = { 'title' => 'Grocery List', 'items' => [] }
grocery_item = { 'title' => 'Bread', 'quantity' => 1 }

Hey Leonardo,

You've pretty much got it, except for the type of 'brackets' after push. Remember push is a method, and therefore uses parenthesis, not curly braces. Just change those and you're good.

grocery_list['items'].push(grocery_item)

Keep Coding! :)
