README

This package helps returning JSON API compliant errors while using the native Laravel validation logic. Also, it lets you add unique codes to your validation rules which makes it easier on the consumer end.

Laravel / Lumen Versions

Installation

You can install the package via composer:

Laravel / Lumen 10

composer require "nestecha/laravel-json-api-validation":"^5.0"

Laravel / Lumen 9

composer require "nestecha/laravel-json-api-validation":"^4.0"

Laravel / Lumen 8

composer require "nestecha/laravel-json-api-validation":"^3.0"

Laravel / Lumen 7

composer require "nestecha/laravel-json-api-validation":"^2.0"

Laravel / Lumen 6

composer require "nestecha/laravel-json-api-validation":"^1.0"

Go in App\Exceptions\Handler.php and change the render method :

/**
 * Render an exception into an HTTP response.
 *
 * @param  \Illuminate\Http\Request  $request
 * @param  \Exception  $exception
 * @return \Illuminate\Http\Response|\Illuminate\Http\JsonResponse
 */
public function render($request, Exception $exception)
{
    if ($exception instanceof \Nestecha\LaravelJsonApiValidation\Exception\JsonApiValidationException) {
        $responseFactory = new \Nestecha\LaravelJsonApiValidation\ResponseFactory();
        return $responseFactory->fromErrors($exception->errors()->getArrayCopy());
    }

    return parent::render($request, $exception);
}

Then, in your controller :

public function home(Request $request)
{
    $validator = new \Nestecha\LaravelJsonApiValidation\JsonApiValidator();
    $validator->validateAsJsonApi($request->all(), ['title' => 'required']);

    // ...
}

This would yield :

{
    "errors": [
        {
            "status": "422",
            "title": "Unprocessable Entity",
            "detail": "The title field is required.",
            "source": {
                "pointer": "\/data\/attributes\/title",
                "value": ""
            },
            "meta": {
                "failed": {
                    "rule": "required"
                }
            }
        }
    ]
}

For Laravel :

To add a code to the errors, use this artisan command to copy the default config file to your config folder.

php artisan vendor:publish --tag=config

For Lumen :

To add a code to the errors, a base config file is available, simply copy paste it into your config folder as json-api-validation.php. Then in bootstrap/app.php add this line :

$app->configure('json-api-validation');

To customize the config filename :

json-api-validation.php is the default config filename. You can customize the validator by passing a string in the constructor :

public function home(Request $request)
{
    $validator = new JsonApiValidator('name-of-your-config-file');
    $validator->validateAsJsonApi($request->all(), ['title' => 'required']);
}

For custom rules :

When using Laravel custom rules :

class UppercaseRule implements Rule
{
    /**
     * @inheritDoc
     */
    public function passes($attribute, $value)
    {
        return strtoupper($value) === $value;
    }

    /**
     * @inheritDoc
     */
    public function message()
    {
        return "The :attribute should be uppercase.";
    }
}

To add an error code in the config, you should use the name in kebab-case format :

return [
    'uppercase-rule' => ['code' => 'VALIDATION_ERROR_UPPERCASE'],
];

The error will format the rule name in kebab-case in the meta field :

{
    "errors": [
        {
            "status": "422",
            "title": "Unprocessable Entity",
            "detail": "The title should be uppercase.",
            "source": {
                "pointer": "\/data\/attributes\/title",
                "value": "lowercase_title"
            },
            "meta": {
                "failed": {
                    "rule": "uppercase-rule"
                }
            }
        }
    ]
}
