product.ingredients is an array, you could reference product.ingredients[0].name or you could iterate the array using product.ingredients.each. Another useful construct is product.ingredients.map(&:name) which will give you an array of ingredient names. In all of this don't forget to watch out for a product with no ingredients (product.ingredients is nil in this case) which can give you run-time errors if you have not caught them. The same applies to stack.products. I wonder whether it would be useful for you to run through some basic Ruby tutorials to get a bit more grounding on the basics of Ruby.
