Ruby Ruby Collections Ruby Hashes Working with Hash Values

Am I adding the new key to the hash correctly?

I'm not sure if I'm using the method for adding a new set of key/value to an existing hash that the challenge wants.

hash.rb 
grocery_item = { "item" => "Bread", "quantity" => 1, "brand" => "Treehouse Bread Company" }
if grocery_item.has_value?("Bread")
  grocery_item[:food] = "true"
end

The challenge wants you to set the value to the boolean true not a string.

Try getting rid of the double quotes around the true value :)

Good luck! ~alex

Tried that (as that's what I then next thought) and got " Bummer! The key food was not found in the grocery_item hash." So hm.

True should be a boolean and not a string so remove them double quotes.

There are a few ways of adding a new Key -> Value pair to a hash and what you have done isn't wrong, but the test needs you to assign the key as a string to get it to pass. 

grocery_item = { "item" => "Bread", "quantity" => 1, "brand" => "Treehouse Bread Company" }
if grocery_item.has_value?("Bread")
  grocery_item['food'] = true
end

This should pass. Its worth noting that you can use strings or symbols as hash keys. There is a difference and its worth researching.
