I'm struggling with the second part of these questions--setting the value or variable to be true...

How do I set the value or variable to be true?

hash.rb 
grocery_item = { "item" => "Bread", "quantity" => 1, "brand" => "Treehouse Bread Company" }
grocery_item.has_value?("bread")

So what this challenge is wanting you to do is check to see if a value exist in the hash, and if it does, create a new key with the value of true.

So this is the code that worked for me.

First you want to use an if statement to check to see if the value exist in the has. Then if the value is found, you want to create a new key in the hash with the value of true. If the value is not found, you don't need to do anything.

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

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