¿ 19/6/2007 - Selecting a different RJS file to display in Ruby on Rails

Sometimes you have a many tasks that send some data to a server, and all of them result in the same line in the same list being updated.

Instead of making several method_name.rjs files, make one called update.rjs, and then add an empty method to your controller called "update"

Then at the end of each of the methods that need to update the record, do the following:

render => { :action => :update }

That way you can keep your views directory clutter free.

An example would be:

  def up
    @item = Item.find(params[:id])
    @item.move_higher
    do_list
    render :action => 'update'
  end

  def down
    @item = Item.find(params[:id])
    @item.move_lower
    do_list
    render :action => 'update'
  end

  def top
    @item = Item.find(params[:id])
    @item.move_to_top
    do_list
    render :action => 'update'
  end

  def bottom
    @item = Item.find(params[:id])
    @item.move_to_bottom
    do_list
    render :action => 'update'
  end

  def update
  end
end


# updae.rjs:

page.replace_html active_scaffold_content_id, :partial => "list"
