How to reorder rows in a table?
Hi, I have a link table with a location field, here is the code I wrote to reorder the rows # move_up action in links controller def move_up current_link = Link.find(params[:id]) current_link.location -= 1 current_link.save same_link = Link.find_by_location(current_link.location) same_link.location += 1 same_link.save redirect_to :action => ''list'' end But it does not work always, can''t figure it out. What may be the problem? Is there a better way to do this? Thanks
