values shows you what is currently in the values hash. As you used
Employee for the initial load, it will contain only columns in the
employees table. For the other values, you call the method, and the method
will load the value:
e.num_staff #=> 3
If you want to populate the values for all columns:
e.class.columns.each{|c| e.send(c)}
e.values
