What is the more "rails-like"? If I want to modify a model's property when it's set, should I do this:

  def url=(url)
    #remove session id
    self[:url] = url.split('?s=')[0]
  end

or this?

  before_save do |record|
    #remove session id
    record.url = record.url.split('?s=')[0]
  end

Is there any benefit for doing it one way or the other? If so, why? If not, which one is generally more common?
