Laravel Composite Key Laravel Package

mpociot/laravel-composite-key adds first-class support for composite primary keys to Laravel's Eloquent ORM. Instead of forcing a single auto-incrementing ID, models can define an array of key columns and let the package handle lookups, persistence, and key generation behind the scenes.

It is designed as a drop-in trait for existing Eloquent models, keeping composite-key logic isolated while preserving normal model behavior.

• Define multiple primary key columns via $primaryKey
• Supports Eloquent find, save, and delete operations
• Generates and resolves composite key values automatically
• Works with existing models through a simple trait
• Keeps key handling out of your application code
