Using the values_at method, create an array called grocery_list with the value of the grocery_item hash at the "item" ke

what should i do?

hash.rb 
grocery_item = { "item" => "Bread", "quantity" => 1, "brand" => "Treehouse Bread Company" }


grocery_item["food"] = false
if grocery_item.has_value?("Bread")
  grocery_item["food"] = true
end

grocery_list = Array.new
grocery_list("item", grocery_item.values_at("item"))

Hi there,

The line grocery_item.values_at("item") returns an array so you could directly assign it to grocery_list instead of creating an empty one.

thanks Raymond!

I'm still stuck on this one.. this is where I am: grocery_item = { "item" => "Bread", "quantity" => 1, "brand" => "Treehouse Bread Company" }

grocery_item["food"] = false if grocery_item.has_value?("Bread") grocery_item["food"] = true end

grocery_list.unshift("item", grocery_item.values_at("item"))

IT GIVES ME: OOPS! LOOKS LIKE TASK ONE IS NO LONGER PASSING.

grocery_item = { "item" => "Bread", "quantity" => 1, "brand" => "Treehouse Bread Company" }

grocery_item["food"] = false if grocery_item.has_value?("Bread") grocery_item["food"] = true end

grocery_item.values_at(grocery_list)

this is still working :/

Hi Gad,

It looks like the part you're having trouble with is using hash methods for arrays which is very common. Changing task 2 to this line should solve it:

grocery_list = grocery_item.values_at("item")

I hope this was helpful and good luck!
