What Doctrine relationship types are supported?

The skill covers all primary Doctrine associations: ManyToOne, OneToMany, ManyToMany, and OneToOne, including their bidirectional configurations.

How does this skill help with database performance?

It provides specific patterns for Join Fetching and EXTRA_LAZY loading to eliminate the N+1 query problem, ensuring your Symfony application remains fast as your data scales.

Can I use it for complex self-referencing models?

Absolutely. It includes specific guidance for self-referencing relationships, which are ideal for building hierarchical structures like category trees or parent-child page systems.

Does it handle bidirectional relationships correctly?

Yes, it includes best-practice patterns for synchronizing both the owning and inverse sides of associations within the entity's add and remove methods.

Does it help with database indexing?

Yes, it provides patterns for indexing foreign keys to ensure that relationship-based queries are optimized at the database level.

Database Management

Configures and optimizes Doctrine ORM entity relationships, fetch modes, and cascade operations for Symfony applications.

About

This skill empowers Claude to architect robust database schemas within Symfony by implementing best-practice Doctrine entity relationships. It provides deep expertise in defining bidirectional OneToMany, ManyToMany, and OneToOne associations, configuring performance-critical fetch modes like EXTRA_LAZY, and managing complex cascade operations. Crucially, it helps developers identify and eliminate N+1 query performance bottlenecks through efficient join fetching, indexing strategies, and automated side-synchronization in entity methods.

Key Features

Performance optimization techniques to detect and fix N+1 query issues
Granular control over cascade operations and orphan removal logic
21 GitHub stars
Implementation of bidirectional and self-referencing entity relationships
Advanced fetch mode configuration including LAZY, EAGER, and EXTRA_LAZY
Standardized boilerplate for adding/removing entities while maintaining side synchronization

Use Cases

Modeling complex data structures such as nested categories, user profiles, or social media tags
Refactoring existing Doctrine entities to improve database performance and query efficiency
Implementing automated cascading deletes and persistence for parent-child data models
