I have a Rails app that has a seq (sequence number field). I’d like it to be an invisible field, and for it to auto-increment, but be separate from the id.
On the index page, I’d like to be able to drag-and-drop the rows to re-sequence them, and the sequence should then go from 1 to the highest row.
What’s the easy way to do this or can anyone suggest a tutorial I could follow?
