I assume "has_value?" search for the "value", right? Then, how can I use this method to search string like this code challenge? Does this code work if I wrote "has_key?"?
grocery_item = { "item" => "Bread", "quantity" => 1, "brand" => "Treehouse Bread Company" }
if grocery_item.has_value? ("Bread")
food = true
end

The has_value? method returns true if the object it is called upon, in this case the grocery_item hash, contains the value that you specify; Bread in this case. You are correct that has_key? also exists.
In your code, you have called the method correctly. However, your statement inside the if conditional isn't quite right. You need to add the new pairing to the grocery_list hash, not just set a variable to true. You need to create a new key, "food" and assign it a value of true.
That could look like:
grocery_item = { "item" => "Bread", "quantity" => 1, "brand" => "Treehouse Bread Company" }
if grocery_item.has_value?("Bread")
grocery_item["food"] = true
end
I hope that helps,
Steve.
