Rejectconf did not disappoint, delivering the inside scoop on the really advanced and cutting-edge Rails stuff. I presented my upcoming unit of work concept, which lets you write your controller methods the following way:

class IterationController < ActionController::Base
  include Renaissance::UnitOfWork
  
  def create
    case unit_of_work do
      @iteration = Iteration.new(params[:iteration])
    end
    
    when Success
      redirect_to iteration_path(@iteration)
      
    when ValidationError
      render :action => 'new'      
    end
    
  end
  
  def update
    case unit_of_work do
      @iteration = Iteration.find(params[:id])
      @iteration.update_attributes(params[:iteration])
    end
    
    when Success
      redirect_to iteration_path(@iteration) and return
    
    when StaleObject
      flash[:error] = "Another user beat you to changes"
      @iteration.refresh_and_apply(params[:iteration])
    end
    
    render :action => 'edit'
  end

end
