i am a beginner rails developer

in rails archies there is no proper relation between Model and 
Controller

inside controller i should create Model object .
At such situation i want to assign some values to model_object 
attributes from controller (without argument passing to model_object ) .
like

nowadays i am doing like this
model_object=Record.find(:first)
model_object.updated_by=session[:user]
model_object.save

but i want like this

class Record < AR
 before_update :assign_updated_by
 protected
  def assign_updated_by
   self.updated_by=session[:user] #or some idea here
  end
end
model_object=Record.find(:first)
model_object.save
.....
any idea...
