Ardent Laravel Package

Product Decisions This Supports

• Validation-Driven Development: Enables self-validating Eloquent models, reducing repetitive validation logic in controllers and reducing boilerplate code. Aligns with a clean architecture approach by encapsulating validation rules within models.
• Domain-Driven Design (DDD): Facilitates the creation of "rich" domain models with built-in business logic and validation, improving code organization and maintainability.
• Rapid Prototyping: Accelerates development by automating validation workflows, allowing teams to focus on core business logic rather than validation rules.
• Build vs. Buy Decision: Justifies a "build" approach for teams already using Laravel, avoiding the need for custom validation layers or third-party services.
• Compliance & Data Integrity: Ensures data consistency by enforcing validation rules at the model level, critical for regulated industries (e.g., finance, healthcare).
• Legacy System Modernization: Helps refactor monolithic controllers by shifting validation logic to models, improving testability and separation of concerns.

When to Consider This Package

• Avoid if:
  • Your team is using Laravel 8+ (Ardent is archived and incompatible with newer Laravel versions; consider alternatives like Laravel Model Observers or Spatie Validation).
  • You need active maintenance or modern PHP features (e.g., PHP 8+ attributes, first-class union types).
  • Your project requires complex nested validation (e.g., deeply nested forms or API payloads); Ardent’s validation may not scale as elegantly as dedicated libraries like VentureCraft/reval.
  • You’re building a new project and prefer a more actively maintained solution (e.g., Laravel’s built-in validation or FluentValidation).
• Consider if:
  • You’re maintaining a Laravel 5.x project and want to reduce validation boilerplate without major refactoring.
  • Your team values explicit model-level validation over controller-based validation.
  • You’re adopting DDD principles and want models to encapsulate business rules.
  • You need lightweight, self-contained validation without external dependencies (beyond Laravel/Eloquent).

How to Pitch It (Stakeholders)

For Executives:

*"Ardent is a lightweight, open-source package that embeds validation logic directly into Laravel models, reducing code duplication and improving data integrity. By shifting validation from controllers to models, we can:

• Cut development time by 20-30% for validation-heavy features (per industry benchmarks).
• Reduce bugs by enforcing rules at the model layer, closer to where data is created/updated.
• Future-proof our architecture with cleaner separation of concerns, making the codebase easier to maintain and scale. This aligns with our DDD/clean architecture roadmap and avoids vendor lock-in, as it’s a self-contained solution within Laravel’s ecosystem."*

For Engineering Teams:

*"Ardent lets us write self-validating Eloquent models, so validation rules live where they belong—in the model, not scattered across controllers or services. Here’s how we’d leverage it:

• Replace repetitive Validator::make() calls in controllers with model-level validation (e.g., if (!$user->save()) { return redirect()->back()->withErrors($user->errors); }).
• Enforce business rules at the model layer (e.g., User::validateRules(['email' => 'required|unique:users'])).
• Integrate seamlessly with Laravel’s existing ecosystem (e.g., works with API resources, form requests, and testing). Trade-offs: It’s archived (last update 2018), so we’d need to vet compatibility with our Laravel version. For new projects, we might explore alternatives, but for Project X, this gives us a quick win with minimal risk. Next steps: I’ll prototype a single model (e.g., User) to demonstrate the reduction in boilerplate and share a PR template for adoption."*

For Developers:

*"Ardent adds a validateRules() method to Eloquent models, letting you define validation rules in the model itself. Example:

class User extends Ardent {
    protected $rules = [
        'name' => 'required|max:255',
        'email' => 'required|email|unique:users',
    ];

    public function validateRules($rules = []) {
        $this->rules = array_merge($this->rules, $rules);
        return parent::validateRules();
    }
}

Why use it?

• No more copying/pasting validation rules across controllers.
• Errors are automatically attached to the model ($user->errors).
• Works with Laravel’s existing validation messages and custom rules. Caveats: Only for Laravel 5.x. For newer versions, we’d need to build a custom solution or use alternative X."*
