Hi,

I’m not using Ruby, but in the “create” method or function you can’t access directly the username instance variable, I guess that you should replace
#{username} by #@username .

best regards

Yup. that was the error.

Do you know why the “initialize” method is not called during the instantiation of the class ? I’m using 'Computer.new ’ instead of ‘Computer.initialize’ .

Try replacing #{Computer.get_users} with #{paul_computer.get_users} in the last line
