What problem does it solve?

Doctrine ORM best practices for Symfony help teams avoid common pitfalls such as N+1 queries, brittle migrations, and inconsistent entity mappings by codifying standards around mapping, queries, and migrations.

Core Features & Use Cases

• Entity mapping with attributes: keep mapping as the source of truth and generate migrations from it.
• Parameterized DQL / QueryBuilder: promote safe, injective queries and prevent SQL injection.
• N+1 prevention: use fetch joins and proper fetch strategies.
• Relations management: configure cascade, fetch, and orphanRemoval for robust aggregates.
• Migrations & lifecycle events: automate migrations with lifecycle hooks for auditability.

Quick Start

Start applying these patterns by configuring your Symfony entities with attributes, validating queries, and enabling migrations to keep schema in sync.
