You're perhaps thinking of accessor methods. The following code:

class Foo
  attr_accessor :bar
end

does effectively the same as this:

class Foo
  def bar
    @bar
  end
  def bar=(val)
    @bar = val
  end
end

For learning about the basics of Ruby, I strongly recommend the book 
Programming Ruby. The first edition is available to view online for 
free:
http://www.ruby-doc.org/docs/ProgrammingRuby/

Since you're already a programmer you should find this very accessible.

HTH,

Brian.
