Eager Loading and N+1 Prevention

Load Relations Explicitly

Post::with(['author', 'comments'])->paginate();

• Use load()/loadMissing() after fetching models when needed
• Select only required columns for both base query and relations

Guard Against Lazy Loading in Dev/Test

Add to a service provider (non-production):

Model::preventLazyLoading(! app()->isProduction());

Verify

• Use a query logger or debugbar to confirm relation queries are minimized
• Add tests that assert counts or avoid unexpected query spikes
