railscasts

I found this in Ryan Bates' railscast site, but not sure how it works.

#models/comment.rb
def req=(request)
self.user_ip    = request.remote_ip
self.user_agent = request.env['HTTP_USER_AGENT']
self.referrer   = request.env['HTTP_REFERER']
 end

#blogs_controller.rb
def create
 @blog = Blog.new(params[:blog])
 @blog.req = request
 if @blog.save
 ...

I see he is saving the user ip, user agent and referrer, but am confused with the req=(request) line. Any help is appreciated.

Thanks
