Laravel When On Relation Laravel Package

laravel-when-on-relation adds a fluent whenOnRelation() macro to Eloquent, letting you conditionally apply query constraints based on the relation a model was loaded through. This keeps eager-loading logic expressive and avoids brittle if checks or duplicated queries when the same model is fetched from different relations.

• Conditionally apply clauses only when loaded via a given relation
• Chainable, fluent API that fits naturally into existing query builders
• Supports nested relation paths and callback constraints
• Reduces duplicated query logic across controllers and repositories
• Fully tested and PSR-4 compliant for Laravel 9+
