React to Doctrine entity lifecycle in Symfony with attribute listeners (#[AsDoctrineListener]/#[AsEntityListener], ORM 3) and lifecycle callbacks.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Doctrine Events (Symfony) ## Use when - You need side effects on entity persistence (timestamps, slugs, search indexing, notifications). - Migrating an `EventSubscriberInterface` Doctrine subscriber to ORM 3. - Choosing between lifecycle callbacks, entity listeners, and global lifecycle listeners. ## Default workflow 1. Pick the narrowest mechanism: callback (one entity, no deps) → entity listener (one entity, needs services) → lifecycle listener (cross-cutting, all entities). 2. Wire it with attributes (`#[ORM\HasLifecycleCallbacks]`, `#[AsEntityListener]`, `#[AsDoctrineListener]`). 3. Type the event argument by its per-event class (`PostPersistEventArgs`, `PreUpdateEventArgs`, …). 4. Verify the side effect fires with a targeted functional test against a real DB. ## Guardrails - ORM 3.0 removed `EventSubscriberInterface` Doctrine subscribers — never reintroduce them. - Type-check the entity early in a global lifecycle listener (it fires for every entity). - Never call `flush()` inside a Doctrine event handler — it corrupts the in-flight unit of work. - `preUpdate` is restricted: change fields only via `$args->setNewValue()`, never touch associations. …

How to install
mdr add dev-toolings/superpowers-symfony/doctrine-events@sha256:616dd07b80d7a76aThe line at the top of this page pins the label git:20261005.042befb, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
