Consider a production Laravel application that needs to use Relationship inclusion. How should the developer approach the requirement, and what should be checked before releasing it? Assume the system receives real users, real data and concurrent requests. The correct approach is to identify where relationship inclusion belongs, define its inputs and outputs, protect the boundary with validation and authorization where applicable, consider database and performance implications, and add automated tests for the expected behavior. Concept-specific reasoning: Resources can include related data when those relationships are intentionally available. A useful implementation pattern is: class ProductResource extends JsonResource { public function toArray($request): array { return [ 'id' => $this->id, 'name' => $this->name, 'price' => $this->price, ]; } }
