sometimes, we want to refresh the data of X table, we do that by "X.delete_all" method.

after that, when you create new a row data which its id is not from 1 begin instead of from

last record before I delete it, how can I operate so that I can get consequence what just I mention at title.

my guess is that this should be handled by the database not rails try ALTER TABLE table AUTO_INCREMENT = 1 or alternatively you can truncate your table

@leozwa Thx, you right, it work for me now!

use SQL truncate
