Subject: in the callback why I must use self


class User < ActiveRecord::Base
  def before_save
    self.name1 = fname + ' ' + lname
    name2 = fname + ' ' + lname
  end
end


In the callback I am using self for name1 and NOT using self for name2.
When a record is saved in the database I get proper value for name1 but
not for name2. Question is why?


In my judgement before name2 whether I use self or not should not matter
because there is an implicit self when there is no receiver. Then why
the difference in behavior?
