Umanit Block Bundle

Doctrine Block managment made easy.

  • Simple implementation
  • Flexible
  • Orderable Blocks
  • Database consistent
  • User friendly
  • Dev friendly

Philosophy

Usually when dealing with blocks, developers lose their database consistency because they have to store many block types in a single table. The most common way of storing many types of blocks in one single table is to store them in a json column.

We think json is bad for database consistency and performances. Searching, indexing, managing relations, primary and unique keys... You name it, none of them is possible with json.

UmanitBlockBundle intends to solve this problem by giving back their entities to the developers.

Front requirements

Install

Register the bundle to your config/bundles.php

<?php

return [
    // ...
    Umanit\BlockBundle\UmanitBlockBundle::class => ['all' => true],
];

Add one of the Twig's form theme

# config/packages/twig.yaml
twig:
    form_themes:
        # When using Sylius, the only available for the moment
        - '@UmanitBlock/sylius/form/panel.html.twig'

Add @umanit/block-bundle dev-dependency in your package.json. This part is automatically done if you use Flex in your projet.

{
  //...
  "devDependencies": {
    // ...
    "@umanit/block-bundle": "file:vendor/umanit/block-bundle/Resources/assets"
  }
}

Add stimulus controllers to your assets/controllers.json. This part is automatically done if you use Flex in your projet.

{
  "controllers": {
    // ...
    "@umanit/block-bundle": {
      "blocks": {
        "enabled": true,
        "fetch": "eager"
      },
      "item": {
        "enabled": true,
        "fetch": "eager"
      },
      "sortable": {
        "enabled": true,
        "fetch": "eager"
      }
    }
  }
  // ...
}

Don't forget to install the JavaScript dependencies as well and compile

yarn install --force
yarn encore dev

Usage

Terminology

  • A Block is a simple Doctrine entity that implements Umanit\BlockBundle\Model\BlockInterface.
  • A Block Manager is a service used to administrate and render a Block.
  • A Panel is a Doctrine entity that contains a collection of ordered Block instances.

Create an entity containing the Panel

Usually, you'll have a content entity (here we'll call it Page) having one or more Panels.

<?php

namespace AppBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Umanit\BlockBundle\Entity\Panel;

/**
 * @ORM\Entity()
 */
class Page
{
    // Your other fields...
    
    /**
     * @var Panel
     *
     * @ORM\ManyToOne(targetEntity="Umanit\BlockBundle\Entity\Panel", cascade={"persist"})
     * @ORM\JoinColumn(name="panel_id", referencedColumnName="id")
     */
    protected $content;
    
    // Getters and Setters...
}

Next, use the provided PanelType form to administrate the Page content.

use Umanit\BlockBundle\Form\PanelType;

$builder->add('content', PanelType::class);

Every block manager is available by default, if you want to filter them, you can give an option authorized_blocks, an array of all the block types allowed to be selected, or unauthorized_blocks, an array of all the block types not allowed to be selected.

use Umanit\BlockBundle\Form\PanelType;

$builder->add('content', PanelType::class, [
    'authorized_blocks' => [MyBlock::class]
]);

$builder->add('content', PanelType::class, [
    'unauthorized_blocks' => [MyBlock::class]
]);

Create a Block entity and its Block Manager

Start by creating your Block entity which should extends the bundle Block entity, like the following example:

<?php

namespace AppBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Umanit\BlockBundle\Entity\Block;

/**
 * @ORM\Entity()
 */
class TitleAndText extends Block
{
    /**
     * @var string
     *
     * @ORM\Column(name="title", type="string")
     */
    private $title;

    /**
     * @var string
     *
     * @ORM\Column(name="text", type="text")
     */
    private $text;
    
    // getters and setters ...
    
    /**
     * 
     */
    public function __toString()
    {
        return $this->getTitle() ? : 'New TitleAndText';
    }
}

Then, create a Block Manager service and it's FormType which should extend AbstractBlockType. This service will define the form used to administrate your Block. It will also allow you to define the rendering of the Block in the front end.

<?php

namespace AppBundle\BlockManager;

use AppBundle\Entity\TitleAndText;
use AppBundle\Form\TitleAndTextType;
use Umanit\BlockBundle\Block\AbstractBlockManager;
use Umanit\BlockBundle\Model\BlockInterface;
use Twig\Environment;
use \Twig\Error\LoaderError;
use \Twig\Error\RuntimeError;
use \Twig\Error\SyntaxError;

class TitleAndTextManager extends AbstractBlockManager
{
    /** @var Environment */
    private $twig;

    /**
     * QuoteBlockManager constructor.
     *
     * @param Environment $twig
     */
    public function __construct(Environment $twig)
    {
        $this->twig = $twig;
    }

    /**
     * Define which Block type is managed by this Manager
     *
     * @return string
     */
    public function getManagedBlockType(): string
    {
        return TitleAndText::class;
    }

    /**
     * This method must return the form typemanaged by this block manager.
     *
     * @return string
     */
    public function getManagedFormType(): string
    {
        return TitleAndTextType::class;
    }

    /**
     * Define how the block should be rendered on the front end.
     *
     * @param BlockInterface $block
     * @param array          $parameters
     *
     * @return string
     * @throws LoaderError
     * @throws RuntimeError
     * @throws SyntaxError
     */
    public function render(BlockInterface $block, array $parameters = []): string
    {
        return $this->twig->render('blocks/title-and-text.html.twig', ['block' => $block]);
    }
}
<?php

namespace AppBundle\Form\TitleAndTextType;

use Umanit\BlockBundle\Form\AbstractBlockType;
use Symfony\Component\Form\Extension\Core\Type\TextareaType;
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\Validator\Constraints\NotBlank;

class TitleAndTextType extends AbstractBlockType
{
    /**
     * Define the form used by the back end to administrate the block.
     *
     * @param FormBuilderInterface $builder
     * @param array                $options
     */
    public function buildForm(FormBuilderInterface $builder, array $options): void
    {
        $builder
            ->add('title', TextType::class, [
                'constraints' => [
                    new NotBlank(),
                ],
            ])
            ->add('text', TextareaType::class, [
                'constraints' => [
                    new NotBlank(),
                ],
            ])
        ;
    }
}

Finally, tag your Block Manager with umanit_block.manager.

# config/services.yml
services:
    app.block_manager.title_and_text_manager:
        class: AppBundle\BlockManager\TitleAndTextManager
        arguments: ['@twig']
        tags: ['umanit_block.manager']

Render your blocks

Use the twig function umanit_block_render to render each of your blocks.

{# page.html.twig #}

{% for block in page.content.blocks %}
    {{ umanit_block_render(block) }}
{% endfor %}

umanit_block_render will find the right BlockManager and call its render method.

You can pass an array of parameters to umanit_block_render. This parameters will be passed to the render method of the BlockManager.

Integration with UmanitTranslationBundle

This bundle is fully compatible with UmanitTranslationBundle. Once translating a Panel, all the Block instances and their properties will also be translated. If you need a locale parameter in you BlockManager form (to filter an EntityType for example), pass the parameter to the PanelType like so:

$builder->add('content', PanelType::class, ['locale' => 'be']);
