Ruby Ruby Loops Build a Simple Contact List Assigning Hash Values From Methods

Ruby quiz on hashes / methods

The quiz question is as follows:

Assign the value of the key name to the return value of the method get_name() in the contact hash. Assume that get_name() returns a string. Given the following:

contact_list = []

contact = {"name" => "", "phone_number" => "" }

my answer starts here:

contact_list = []

contact = {"name" => "", "phone_number" => "" }

def get_name() svalue = "Quiz" return svalue end

contact["name"] = get_name() puts contact["name"] puts contact.inspect

Which appears to work but the auto-grader states:

Bummer! The contact['name'] hash key did not have the value of the get_name() method.

You are doing more than the exercise asks you to do. You have to assume that get_name was already defined somewhere and that you can use it in your program and it will return a string. The only line you need to add to the code provided by Treehouse is:

contact["name"] = get_name()

That works great Maciej. The question should be updated by author to read:

"Assign the value of the key name to the return value of the method get_name() in the contact hash. Assume that get_name() HAS ALREADY BEEN DEFINED and returns a string."

[uppercase means the change requested]

That would have saved me a half hour of hair pulling. :)

I know what you mean, my first instinct was exactly the same in this exercise. You should definitely suggest it to support (you can contact them using the link on the right).
