README

This bundle introduces the @Validator annotation, that gives a possibility to validate a Request data using Symfony Validator Constraints and Annotations. Normally Symfony is defining the assertions in the Entities, with this library we can just use a collection constraint for the request data and it'll pick it up automatically thanks to the @Validator annotation.

Installation

Step 1: Install the bundle

composer require kununu/controller-validation-bundle:dev-master

Step 2: Enable the bundle

// config/bundles.php

return [
    // ...
    Kununu\ControllerValidationBundle\KununuControllerValidationBundle::class => ['all' => true],
];

Configuration

Constraints namespace

You need to define the namespace where your Constraints are located:

# config/packages/kununu_controller_validation.yml
kununu_controller_validation:
    constraints_namespace: App\Validator\Constraints

Custom Validation Exception

You can define your own Exception to be thrown if needed. Otherwise the default ValidationException will be used:

# app/config/config.yml
kununu_controller_validation:
    validation_exception:
        class: App\Exception\ValidationException
        message: Validation error
        code: 400

Listener priority

The ControllerValidatorListener is by default registered with a priority equal to 0. In some cases it is needed to dispatch event earlier or later. That's why listener_priority configuration option was added.

Higher the priority, earlier the event will be dispatched.

# app/config/config.yml
kununu_controller_validation:
    listener_priority: 1

⚠️WARNING: ⚠️ If you're using @ParamConvert annotation, do not change the priority to be less than 0, if you're using any custom ParamConverters. The annotation is going to try to validate the request after the paramConverter is called, which makes no sense if the request is invalid and the actual conversion might fail. If it's absolutely necessary, make sure you manually validate the data in your custom converter, before any other operations.

Note: You can get a list of all registered events using the console command: bin/console debug:event-dispatcher

Usage

Constraints

<?php
// src/Bundle/Validator/Constraints/ExampleConstraints.php
namespace App\Validator\Constraints;

use Symfony\Component\Validator\Constraints;
use Symfony\Component\Validator\Constraints\CollectionValidator;

class ExampleConstraints extends Constraints\Collection
{
    public function __construct()
    {
        parent::__construct([
            'id'          => [
                new Constraints\NotBlank(),
            ],
            'name'        => new Constraints\NotBlank(),
            'example_id'  => [
                new Constraints\NotBlank(),
                new Constraints\Range(['min' => 0,'max' => 42]),
            ],
        ]);
    }

    public function validatedBy()
    {
        return CollectionValidator::class;
    }
}

Controller

<?php
// src/App/Controller/ExampleController.php
namespace App\Controller\ExampleController;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Kununu\ControllerValidationBundle\Annotation\Validator;

class ExampleController extends Controller
{
    /**
     * @param Request $request
     *
     * @Validator("ExampleConstraints")
     */
    public function exampleAction(Request $request)
    {
        // ...
    }
}
