Implementation Guidelines

Query Efficiency & Performance

N+1 Prevention: Always use with() or $with for relationships. Never access relationship properties in a loop without eager loading (N+1 Prevention).
Strict Loading: Call Eloquent::preventLazyLoading(!app()->isProduction()) in AppServiceProvider::boot() to throw LazyLoadingViolationException in local/dev.
Large Datasets: Use chunk(), lazy(), or cursor() for processing many records without memory issues (Memory Efficiency).

Query Logic & Scopes

Reusable Scopes: Define scopeName(Builder $query): Builder methods in models for reusable query filters.
Chaining: Chain scopes (e.g., User::active()->verified()->get()) to keep controllers from duplicating query logic.

Models & Security

Mass Assignment: Always define protected $fillable array; use $request->validated() for Model::create().
Casting: Use protected $casts for dates, JSON, and custom types to ensure data consistency.

Anti-Patterns

No lazy loading: Eager-load with with() or $with; never in loops.
No business logic in Models: Move to Services or Actions.
No raw SQL strings: Use Query Builder or Eloquent methods.
No select *: Specify required columns to limit data transfer.
