assertAutocommit

assertAutocommit(em, operation): void

Defined in: packages/ddd-mikro-orm/src/concurrency/assert-autocommit.ts:22

Rejects an externally active transaction before a write that reports durable success.

The lifecycle decorators treat a resolved save() as durable: @AcknowledgePersisted advances the aggregate’s persisted version baseline and @Cache synchronises or invalidates cache entries. Inside a caller’s transaction neither is true yet — the statement is buffered until a commit this code does not observe, so a later rollback would leave an acknowledged aggregate and a cache reflecting a write that never landed. Participating in an outer transaction needs commit callbacks or unit-of-work semantics; it must not be emulated by acknowledging early.

Call it before issuing the statement, so a rejected operation mutates nothing.

Parameters

em

EntityManager

The entity manager the operation will execute on.

operation

string

Name used in the error message, e.g. 'optimisticDelete'.

Returns

void

Throws

When em is inside an active transaction.
