oh... you can add column named sync_state in table to judge.
for example: person A modify a record in local with offline, sync_state = update person B modify the same record in local with online, sync_state = update too. when you sync the data from local to server side, if primary both id and sync_state are same , the data not be saved in server side and send a error message by Workerpool to page.
