Ruby Ruby Collections Ruby Hashes Working with Hash Keys

The food variable was not found... Why not!

It works fine in Workspaces, but not in the code challenge. Very frustrating. If anybody can spot what is going on I would appreciate it.

I imagine it's a bug in the script that checks for the food variable, but I'm not seeing anybody else having problems.

Thanks!

hash.rb 
hash = { "name" => "Bread", "quantity" => 1, "calories" => 100 }

if hash.has_key?("calories")
  hash.store("food", true)
end

Hi Matt,

Using the has_key? method, check if the hash variable has a key called "calories". If it does, set a new variable called "food" to true.

It asks you to set a new variable and not create a new key with that value.

You need to create a new variable, not add a new key to the hash:

hash = { "name" => "Bread", "quantity" => 1, "calories" => 100 }

if hash.has_key?("calories")
  food = true
end
