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

Error encountered after appending hash to array. Code Challenge 3 of 3

Hello,

I'm working on Stage 3 of "Build A Simple Contact List", and in Code Challenge 3 of 3, you are asked to "Append the contact hash to the contact_list array." I enter the code that - to my understanding - should work:

contact_list.push(contact)

Error message: "Bummer! The contact_list array did not contain the contact hash."

Entire code listed below:

contact_list = []

contact = {"name" => get_name, "phone_number" => get_phone_number } def get_name return "" end

def get_phone_number return "" end contact_list.push(contact)

Thanks, in advance, Rachman

contact.rb 
contact_list = []

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

I believe you don't need to add the get_name and get_phone_number methods yourself.

All you really need to do is:

contact_list = []

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

contact_list << contact

This should work just fine. I'm guessing the test assumes the get_name and get_phone_number methods are already defined elsewhere, and is probably looking to see if what they returned is present in the hash.

Hope this helps!

Hi Raven, Thanks for replying; I tried contact_list << contact contact_list.push(contact) and I'm still getting the error message. I've run out of options to try, at least for now.

Oh you don't have to add contact_list.push(contact)The contact_list << contact is just a shorthand way of writing the same thing.

I tried Raven's solution of contact_list << contact and it worked like a charm. Thanks!
