"The 'has_value' method was not called" why?

Please Help

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

Did you watch and understand the previous videos about hashes? How do you add key and value to a hash? This way:

grocery_item.store("food", true)

It's all here, in the previous lesson, even in the teacher's notes:
