Formable Symfony Bundle

Why?

Because the cleanest way to transfer data from a web request to the domain is by using DTOs. For simple DTOs Symfony forces you to create 2 classes, the FormType class and the SomethingDTO class.

How?

This Bundle allows you to describe DTOs by the annotation @Formable(). Let's see an example.

Example

The Data Transfer Object

use Formable\Definition\Formable;
use Symfony\Component\Validator\Constraints as Assert;

class PublishPostCommand
{
    /**
     * @Formable(name="title", dataType="text")
     *
     * @Assert\Length(max=250)
     */
    public $title;

    /**
     * @Formable(name="content", dataType="text")
     */
    public $content;

    /**
     * @Formable(name="tags", dataType="collection", options={
     *   "type"="text",
     *   "allow_add"=true
     * })
     *
     * @Assert\Count(
     *   min = "2"
     * )
     *
     */
    public $tags;

    /**
     * @Formable(name="date", dataType="date", options={
     *   "widget"="single_text",
     *   "format"="yyyy-M-d"
     * })
     */
    public $date;
}

Embedded DTOs

    /**
     * @var
     *
     * @Formable(name="moneyDTO", class="Formable\Tests\Integration\DTOs\TestMoneyDTO")
     */
    public $moneyDTO;

The Controller

public function publishAction(Request $request)
{
    $publishCommand = new PublishPostCommand();
    $publishCommand->date = new \DateTime('now');
    
    $form = $this->get('trt.formable')->generate($publishCommand);
    $form->submit($request->request->all(), false /* Do not clear missing data */);
    
    if ($form->isValid()) {
        ...
    }
}

The annotation in depth

The @Formable() annotation follows the Symfony\Component\Form\FormBuilderInterface interface.

ARGUMENTS:

• name: [string] the field name
• dataType: [string] the FormType
• options: [array] the FormType options

    /**
     * @Formable(name="date", dataType="date", options={
     *   "format"= IntlDateFormatter::MEDIUM,
     *   "days" = {1,2,3,4}
     * })
     */
    public $date;

Installation

composer require trt/formable

// Register the Bundle

class AppKernel extends Kernel
{
    public function registerBundles()
    {
        $bundles = array(
            ...
            new \Formable\Bundle\FormableBundle(),
        );

        return $bundles;
    }

}
