Transaction conflict?

[Tony.Nguyen]

Without seeing your code, it’s hard to guess the issues. Using @tables.in_transaction might help resolve the conflict

[ANSWERED] Auto Incrementing Field

Eek. No need for any of these shenanigans! Just use a transaction: # Assume there's a table called 'Counter' with a single column ('value') # and a single row: @tables.in_transaction def get_next_value_in_sequence(): row = app_tables.counter.get() row['value'] += 1 return row['value'] Anvil’s transactions are fully serialisable, and @tables.in_transaction automatically retries on conflict, so this function will produce a steady continuous sequence.
