Artesaos - Shield

Artesãos Shield provides you a simple way to centralize your validation rules. It was mainly designed to solve the FormRequest rules practice, that is valid outside HTTP requests.

Installing

The package installation can be done with composer by the following command:

composer require artesaos/shield

Shield does not provides Facades or ServiceProviders, they aren't needed.

Usage

1 - Defining Rules

Operating Shield is simple. It starts by defining a rules class for your model or other kind of entity. Take a look on the following example:

<?php

namespace App\Domains\Users\Rules;

use Artesaos\Shield\Rules

class UserRules extends Rules
{
	public function defaultRules()
	{
		return [
			'name' => 'required|min:6',
		];
	}

	public function creating($callback=null)
	{
		// returnRules method should be used
		// whenever the rules should be merged
		// with the default ones.
		return $this->returnRules([
			'email' => 'required|email',
		], $callback);
	}

	// any other methods / actions that needs rules

}

2 - Enabling Rules

You could instantiate the rules by hand, but the recommended way of doing it is setting a static property into the class that owns the rules and using the proper trait

<?php

// some other use statements here
use Artesaos\Shield\HasRules;
use App\Domains\Users\Rules\UserRules;

class User extends Model
{
	// using the rules trait
	use HasRules;

	// setting the rules class
	protected static $rulesFrom = UserRules::class

	// some model stuff here
}

3 - Usage

Whenever you need to access the rules, you can do it by creating a new instance of the rules class, or just using the classes (mainly models) you enabled.

User::rules()->creating();

User::rules()->updating();

User::rules()->yourCustomMethodForACustomAction();

User::rules()->whatever();

A really nice way of using it inside FormRequests are by passing the current HTTP method, that will be translated to the corresponding rules method (that's a convention)

// inside a form request
User::rules()->byRequestType($this->getMethod());

// wherever you have a request instance
User::rules()->byRequestType($request->getMethod());
