Thanks for your answer. As usually, things are clearer, but more
questions arise.
When I removed "self", leaving just
name = name.gsub(/[^A-Za-z]/, "") if attribute_present?("name")
I got exception saying I try to call gsub on null. Now this is strange...
If you could also explain how ruby can think "name" on the left side
is method. It has "=" sign on the right, is it possible with methods?
I come from java (and earlier C++) world, and I can see in ruby many
things are sooo different. It's not new programming language. It's new
way of thinking. That's why I wanna learn it.
Best regards
