Trying to store the key "food" in my hash if the statement = true

Not sure what I'm doing wrong here.

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

First, the string is case sensitive, in the has_value? use "Bread" with big B. You have to add a new key,value pair to the existing hash, you do that by doing this:

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

Thank you, I was struggling with this one. I forgot that t was case sensitive. Also adding the value to the hash I had correct the first time, I changed it to just adding a value because I thought that's where the problem was.

I tried the code you displayed and it keeps telling me it's not find food in the hash?

I guess this is what you trying to do?

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

if grocery_item.has_value?"bread".capitalize grocery_item['item'] = "food" end
