README

This bundle is highly inspired from KnpLabs/DoctrineBehaviors. Some behaviors have been modified because they didn't accomplish exactly what we wanted.

New behaviors have been added : Uploadable, Metadatable and Taggable.

The original behaviors have been wrapped in a Symfony2 bundle.

PHP 5.4 is required because we use traits.

For now, these behaviors are available :

How to use

Translatable

The entities

You have to generate both Translatable and Translation entities. For example, Text and TextTranslation :

# Text.orm.yml
Unifik\SystemBundle\Entity\Text:
  type: entity
  fields:
    id:
      type: integer
      id: true
      generator:
        strategy: AUTO
    createdAt:
      type: datetime
      gedmo:
        timestampable:
          on: create
    updatedAt:
      type: datetime
      gedmo:
        timestampable:
          on: update
# TextTranslation.orm.yml
Unifik\SystemBundle\Entity\TextTranslation:
  type: entity
  fields:
    id:
      type: integer
      id: true
      generator:
        strategy: AUTO
    text:
      type: text
    name:
      type: string
      length: 255
      nullable: true
    active:
      type: boolean
      nullable: true

In the Translatable entity, add a use statement to include the Translatable trait

<?php

namespace Unifik\SystemBundle\Entity;

use Unifik\DoctrineBehaviorsBundle\Model as UnifikORMBehaviors;

/**
 * Text
 */
class Text
{
    use UnifikORMBehaviors\Translatable\Translatable;

    /**
     * @var integer $id
     */
    protected $id;
    
    [...]
}

In the Translation entity, add a use statement to include the Translation trait

<?php

namespace Unifik\SystemBundle\Entity;

use Symfony\Component\Validator\ExecutionContextInterface;

use Unifik\DoctrineBehaviorsBundle\Model as UnifikORMBehaviors;

/**
 * TextTranslation
 */
class TextTranslation
{
    use UnifikORMBehaviors\Translatable\Translation;

    /**
     * @var integer $id
     */
    protected $id;
    
    [...]
}

You're done! The locale field and the bidirectional relation are automatically registered to the entity's classMetadata with Doctrine Event Listeners with the following names :

// $translations property
$textTranslations = $text->getTranslations();

// $translatable property
$text = $textTranslation->getTranslatable();

// $locale property
$locale = $text->getLocale()

Translated entities are loaded with the current locale on a postLoad Doctrine Event. If you want to load an entity in a specific locale, you can use the "setCurrentLocale" method :

$text->setCurrentLocale('fr');
$name = $text->getName(); // Will return the 'fr' version of the $name property

The forms

You need to build a form for both the Translatable and the Translation entities, and embed a TranslationForm on the translation property :

/**
 * Text Type
 */
class TextType extends AbstractType
{
    /**
     * Build Form
     *
     * @param FormBuilderInterface $builder The builder
     * @param array                $options Form options
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('translation', new TextTranslationType())
        ;
    }
    
    [...]
}
/**
 * Text Translation Type
 */
class TextTranslationType extends AbstractType
{
    /**
     * Build Form
     *
     * @param FormBuilderInterface $builder The builder
     * @param array                $options Form options
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('active', 'checkbox')
            ->add('name')
            ->add('text', 'textarea', array('label' => 'Text', 'attr' => array('class' => 'ckeditor')))
        ;
    }
    
    [...]
}

In twig, you can simply render the form with form_rest or field by field :

<table class="fields" cellspacing="0">

    {{ form_row(form.translation.active) }}

    {{ form_row(form.translation.name) }}

    {{ form_row(form.translation.text) }}

    {{ form_rest(form) }}

</table>

TranslatableEntityRepository

This trait is related to the Translatable behavior. It handles automatic LEFT/INNER JOIN on Translation tables to avoid additional queries to fetch the translation rows, when using the find, findBy, findOneBy and findAll methods.

To use this trait, you need to extend the Doctrine\ORM\EntityRepository and implement the Symfony\Component\DependencyInjection\ContainerAwareInterface, as follow :

<?php

namespace Unifik\SystemBundle\Entity;

use Unifik\DoctrineBehaviorsBundle\Model as UnifikORMBehaviors;

use Doctrine\ORM\EntityRepository;
use Symfony\Component\DependencyInjection\ContainerAwareInterface;

/**
 * SectionRepository
 */
class SectionRepository extends EntityRepository implements ContainerAwareInterface
{
    use UnifikORMBehaviors\Repository\TranslatableEntityRepository;
}

Sluggable

This behavior is pretty simple to implement with only two steps :

Trait

The trait will be used to add a slug field to the entity's metadataClass and to configure the slug field.

You need to add a use statement to include the sluggable trait and define the getSluggableFields method (declared as abstract in the trait) to configure the fields (1 or more) to slug :

<?php

namespace Unifik\SystemBundle\Entity;

use Unifik\DoctrineBehaviorsBundle\Model as UnifikORMBehaviors;

/**
 * SectionTranslation
 */
class SectionTranslation
{
    use UnifikORMBehaviors\Sluggable\Sluggable;

    /**
     * @var integer $id
     */
    protected $id;
    
    [...]
    
    /**
     * Get Sluggable Fields
     *
     * @return array
     */
    public function getSluggableFields()
    {
        return array('name');
    }
    
}

Other methods can be overloaded to configure the behavior :

  • getIsSlugUnique : Determines whether the slug is unique or not. Default is true (It supports the translatable behavior by looking for a similar slug in the current locale only).
  • getSlugDelimiter : The slug delemiter. Default is -.
  • getRegenerateOnUpdate : Determines if the slug should be regenerated when a sluggable field has been modified. Default is true. If set to false, the slug will be regenerated only if the slug field is set to NULL or an empty string.

Service

There is no need to create a service is you wish to use the default behavior.

When the slug is configured to be unique (via the getIsSlugUnique method in the entity/trait), a QueryBuilder is used to make a query on the entity's table to find a slug similar (in the same locale if it's a Translation entity) to the one generated by this behavior. While a slug is found, the slug will be appended by "-1", "-2", and so on. Optionally, you can create a new service and override the default getSelectQueryBuilder method to specify a different QueryBuilder. The QueryBuilder must find a slug similar to the entity's one, on other entities.

Simply use your own class for the service as follow :

services:
    unifik_system.section_translation.sluggable.listener:
        class: %unifik_system.section_translation.sluggable.listener.class%
        tags:
            - { name: doctrine.event_subscriber, type: sluggable, entity: Unifik\SystemBundle\Entity\SectionTranslation }

The class needs to extend the SluggableListener abstract class.

Here is an example of a custom service. We try to find a similar slug only on entities having the same parent than the sluggable's one :

// SectionTranslationSluggableListener.php

<?php

namespace Unifik\SystemBundle\Lib;

use Unifik\DoctrineBehaviorsBundle\ORM\Sluggable\SluggableListener;

use Doctrine\ORM\EntityManager;
use Doctrine\ORM\QueryBuilder;

/**
 * Class SectionTranslationSluggableListener
 */
class SectionTranslationSluggableListener extends SluggableListener
{

    /**
     * Returns the Select QueryBuilder that will check for a similar slug in the table
     * The slug will be valid when the Query returns 0 rows.
     *
     * @param string $slug
     * @param mixed $entity
     * @param EntityManager $em
     *
     * @return QueryBuilder
     */
    public function getSelectQueryBuilder($slug, $entity, EntityManager $em)
    {
        $translatable = $entity->getTranslatable();

        $queryBuilder = $em->createQueryBuilder()
                ->select('DISTINCT(s.slug)')
                ->from('Unifik\SystemBundle\Entity\SectionTranslation', 's')
                ->innerJoin('s.translatable', 't')
                ->where('s.slug = :slug')
                ->andWhere('s.locale = :locale')
                ->setParameters([
                        'slug' => $slug,
                        'locale' => $entity->getLocale()
                ]);

        // On update, look for other slug, not the current entity slug
        if ($em->getUnitOfWork()->isScheduledForUpdate($entity)) {
            $queryBuilder->andWhere('t.id <> :id')
                ->setParameter('id', $translatable->getId());
        }

        // Only look for slug on the same level
        if ($translatable->getParent()) {
            $queryBuilder->andWhere('t.parent = :parent')
                ->setParameter('parent', $translatable->getParent());
        }

        return $queryBuilder;
    }

}

Uploadable

The uploadable behavior simplifies the way you handle file upload in Symfony2. A trait is used to configure the uploadable fields and you only have to add 2 properties :

  • A property that will contain the filename and will be persisted
  • A non-persisted property that will contain the submitted file as an \Symfony\Component\HttpFoundation\File\UploadedFile entity

The config

You can optionally define what is your upload root (absolute) and web (relative to /web) folder by adding these lines to the config.yml file :

unifik_doctrine_behaviors:
    uploadable:
        upload_root_dir: ../web/uploads
        upload_web_dir: /uploads

The ../web/uploads and /uploads paths are the default values. If you wish to use the default paths, you don't have to add anything to config.yml.

You will be able to specify a different subfolder of upload_root_dir for each uploadable field in your entity, we'll see how later on.

The entities

First, you will have to add a non-persisted property and add a use statement to include the Uploadable trait.

This trait contains the getUploadableFields abstract method that you will need to define in your entity. This method returns a key => value array of the list of uploadable fields (key) with their respective upload directory (value).

You can add as many uploadable fields as you wish. In this example, we'll add two uploadable fields, as follow :

<?php

namespace Unifik\SystemBundle\Entity;

use Symfony\Component\HttpFoundation\File\UploadedFile;

use Unifik\DoctrineBehaviorsBundle\Model as UnifikORMBehaviors;

/**
 * Section
 */
class Section
{
    use UnifikORMBehaviors\Uploadable\Uploadable;
    
    /**
     * @var integer
     */
    private $id;
    
    /**
     * @var UploadedFile
     */
    private $image;

    /**
     * @var UploadedFile
     */
    private $otherImage;

    /**
     * Get the list of uploabable fields and their respective upload directory in a key => value array format.
     *
     * @return array
     */
    public function getUploadableFields()
    {
        return [
            'image' => 'images',
            'otherImage' => 'autres_images'
        ];
    }
    
    /**
     * @param UploadedFile $image
     */
    public function setImage($image)
    {
        $this->setUploadedFile($image, 'image');
    }

    /**
     * @return UploadedFile
     */
    public function getImage()
    {
        return $this->image;
    }

    /**
     * @param UploadedFile $otherImage
     */
    public function setOtherImage($otherImage)
    {
        $this->setUploadedFile($otherImage, 'otherImage');
    }
    
    /**
     * @return UploadedFile
     */
    public function getOtherImage()
    {
        return $this->otherImage;
    }

    [...]
}

Note: The UploadedFile properties setters will have to call the trait method setUploadedFile with 2 arguments, the UploadedFile instance and the name of the field. This method will handle the file naming and the file deleting in case of a file replacement.

Next, you'll have to add a persisted field for each uploadable field to your entity's schema. The name of each persisted property will be the name of the non-persisted field suffixed by "Path". In this example, for $image we'll have $imagePath and for $otherImage, we'll have $otherImagePath :

# Section.orm.yml

Unifik\SystemBundle\Entity\Section:
  type: entity
  fields:
    id:
      type: integer
      id: true
      generator:
        strategy: AUTO
    imagePath:
      type: string
      length: 255
      nullable: true
    otherImagePath:
      type: string
      length: 255
      nullable: true

Generate the getters and the setters :

// Section.php
  
    [...]

    /**
     * @param string $imagePath
     */
    public function setImagePath($imagePath)
    {
        $this->imagePath = $imagePath;
    }

    /**
     * @return string
     */
    public function getImagePath()
    {
        return $this->imagePath;
    }

    /**
     * @param string $otherImagePath
     */
    public function setOtherImagePath($otherImagePath)
    {
        $this->otherImagePath = $otherImagePath;
    }

    /**
     * @return string
     */
    public function getOtherImagePath()
    {
        return $this->otherImagePath;
    }
    
    [...]

Other methods can be overloaded to configure the behavior :

  • getNamingStrategy : Determines the naming strategy to use when renaming files with the alphanumeric naming strategy. Available choices are alphanumeric, random and none. See the phpdoc for a detailed description. Default is alphanumeric.
  • getAlphanumericDelimiter : The delemiter when using the alphanumeric naming strategy. Default is -.
  • getIsUnique : Determines whether the filename should be unique or not. Default is true. If true, the trait will generate a unique filename by appending "-1", "-2" and so on to the filename. If set to false and the uploaded file name already exists on the disk, it will be overwrited.

The form

Simply add a new file field to your form type and you're done :

<?php

namespace Unifik\SystemBundle\Form\Backend;

/**
 * Section Type
 */
class SectionType extends AbstractType
{
    /**
     * Build Form
     *
     * @param FormBuilderInterface $builder The Builder
     * @param array                $options Array of options
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('image', 'file')
            ->add('otherImage', 'file')
        ;
    }

    [...]
}

Controller

The upload process is handled by this listener.

When an entity is deleted or when a file is replaced, the files get automatically deleted from the server.

Timestampable

The timestampable behavior is the easiest one to use, it simply requires to include a Trait in your entity and you're done. The updatedAt and createdAt properties will automatically be added to your entity.

Only add the Timestampable trait to your entity :

<?php

namespace Unifik\SystemBundle\Entity;

use Unifik\DoctrineBehaviorsBundle\Model as UnifikORMBehaviors;

/**
 * Section
 */
class Section
{
    use UnifikORMBehaviors\Timestampable\Timestampable;

    /**
     * @var integer
     */
    private $id;
    
    [...]
}

Blameable

The blameable behavior lets you track which User created, updated or deleted an entity. You can configure a User entity to link with the blameable entities, which means that these entities will have a many-to-one relation with the User entity. If you don't specify a User entity, the name of the current logged User will be used instead and will be saved as string.

To activate the blameable behavior, simply use the Trait in the entity you want to behave as blameable :

<?php

namespace Unifik\SystemBundle\Entity;

use Unifik\DoctrineBehaviorsBundle\Model as UnifikORMBehaviors;

/**
 * Section
 */
class Section extends BaseEntity
{
    use UnifikORMBehaviors\Blameable\Blameable;

    /**
     * @var integer
     */
    private $id;
    
    [...]
}

If you want to create a Many-to-One relation between your User entity and your blameable entities, you can configure the listener to manage automatically the association by setting the user_entity parameter to a fully qualified namespace :

# config.yml

unifik_doctrine_behaviors:
    blameable:
        user_entity: Unifik\SystemBundle\Entity\User

SoftDeletable

SoftDeletable let's you soft-delete an entity, which means that the entity won't be deleted but a deletedAt property will be set with the current timestamp when the entity gets deleted.

To make an entity behave as soft-deletable, simply use the SoftDeletable trait as follow :

<?php

namespace Unifik\SystemBundle\Entity;

use Unifik\DoctrineBehaviorsBundle\Model as UnifikORMBehaviors;

/**
 * Section
 */
class Section extends BaseEntity
{
    use UnifikORMBehaviors\SoftDeletable\SoftDeletable;

    /**
     * @var integer
     */
    private $id;
    
    [...]
}

Here are some examples of use in a controller :

<?php

    $section = new Section();
    $em->persist($section);
    $em->flush();

    // Get id
    $id = $em->getId();

    // Now remove it
    $em->remove($section);

    // Hey, i'm still here:
    $section = $em->getRepository('UnifikSystemBundle:Section')->findOneById($id);

    // But i'm "deleted"
    $section->isDeleted(); // === true
<?php

    $section = new Section();
    $em->persist($section);
    $em->flush();
    
    // I'll delete you tomorow
    $section->setDeletedAt((new \DateTime())->modify('+1 day'));

    // Ok, I'm here
    $section->isDeleted(); // === false
    
    /*
     *  24 hours later...
     */
     
    // Ok I'm deleted
    $section->isDeleted(); // === true

Metadatable

The metadatable behavior lets you specify metadata information on an entity. Three metadata are currently supported : Title, Description and Keywords.

If blank, the metaTitle will be auto-generated using the __toString method of the entity.

To activate the metadatable behavior, simply use the Trait in the entity you want to behave as metadatable :

<?php

namespace Unifik\SystemBundle\Entity;

use Unifik\DoctrineBehaviorsBundle\Model as UnifikORMBehaviors;

/**
 * Section
 */
class Section extends BaseEntity
{
    use UnifikORMBehaviors\Metadatable\Metadatable;

    /**
     * @var integer
     */
    private $id;

    [...]
}

To add the fields to your form, simply extend the MetadatableType and call the parent::buildForm function in the buildForm function :

<?php

namespace Unifik\SystemBundle\Form\Backend;

use Symfony\Component\Form\FormBuilderInterface;
use Unifik\DoctrineBehaviorsBundle\Form\MetadatableType;

/**
 * Section Translation Type
 */
class SectionTranslationType extends MetadatableType
{
    /**
     * Build Form
     *
     * @param FormBuilderInterface $builder The Builder
     * @param array                $options Array of options
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        parent::buildForm($builder, $options);

        $builder
            ->add('someOtherFields');
    }

    [...]
}

Taggable

The taggable behavior lets you add tags to an entity. You can define if your entity uses global tags ou specific entity tags.

To activate the taggable behavior, simply use the Trait in the entity you want to behave as taggable.

The getResourceType() method defines what type of entity this tag is related to. Optionnaly, you can override this function to return the string that you want.

This traits has a $tags property with it's getter/setter. The tags are lazy loaded, no queries are executed to the database until you call the getTags() getter. :

    /**
     * @var ArrayCollection
     */
    protected $tags;

    /**
     * @var \Closure
     */
    protected $tagReference;

    /**
     * @var \DateTime
     */
    protected $tagsUpdatedAt;

    /**
     * Get Tags
     *
     * @return ArrayCollection
     */
    public function getTags()
    {
        // Lazy load the tags, only once
        if (null !== $this->tagReference && null === $this->tags) {
            $tagReference = $this->tagReference;
            $this->tagReference = null; // Avoir circular references
            $tagReference();
        }

        if (null === $this->tags) {
            $this->tags = new ArrayCollection();
        }

        return $this->tags;
    }

    /**
     * Set Tags
     *
     * @param ArrayCollection $tags
     * @return Taggable
     */
    public function setTags($tags)
    {
        $this->tags = $tags;
        $this->setTagsUpdatedAt(new \DateTime());
    }

    /**
     * Add Tag
     *
     * @param Tag $tag
     * @return Taggable
     */
    public function addTag($tag)
    {
        $this->tags->add($tag);
        $this->setTagsUpdatedAt(new \DateTime());

        return $this;
    }

The TaggableType form type has been created to manage the tags via the entity's form.

Two parameters are required by the TaggableType :

  • resource_type: The resource type. The best way is to use the getResourceType() method of the Taggable entity.
  • locale: The locale in which the Tags will be fetched/created.

There are also 3 optional parameters :

  • use_fcbkcomplete: Use the Fcbkcomplete jQuery plugin. This allows you to create tags on the fly. (default: true)
  • allow_add: Allows you to add tags directly in your entity's form. The use_fcbkcomplete option must be set to true. (default: true)
  • use_global_tags: Defines if this form is using global tags or specific entity tags. Global tags will be shared across all other entities using global tags. If set to false, tags will be shared with other entities using the same resourceType (set in the getResourceType() function). (default: true)

There are different ways to add this field to your entity's form. The best way is to use the entity binded to the form on FormsEvents::POST_SET_DATA event. Here are some examples on how to use the TaggableType :

The best way

<?php

namespace Unifik\SystemBundle\Form\Backend;

use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\Form\FormEvents;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;

use Unifik\DoctrineBehaviorsBundle\Form\MetadatableType;

/**
 * Section Translation Type
 */
class SectionTranslationType extends MetadatableType
{
    /**
     * Build Form
     *
     * @param FormBuilderInterface $builder The Builder
     * @param array                $options Array of options
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        parent::buildForm($builder, $options);

        $builder
            ->add('active')
            ->add('name')
            ->add('slug')
        ;
        
        $builder->addEventListener(FormEvents::POST_SET_DATA, function ($event) {
            $form = $event->getForm();
            $form->add('tags', 'taggable', [
                'resource_type' => $event->getData()->getResourceType(),
                'locale' => $event->getData()->getTranslatable()->getCurrentLocale() // Translatable entity
            ]);
        });
    }
    
    [...]
}

There is no code to add to your controller, everything is handled by Listeners on Doctrine events.

If you wish to use the Fcbkcomplete jQuery plugin, simply include the JS and CSS files in your page and use the included Twig Form Theme, as follow :

{# edit.html.twig #}

{% form_theme form with ['form_div_layout.html.twig', 'UnifikDoctrineBehaviorsBundle:Taggable:form_theme.html.twig' %}

<form>
    {{ form_row(form.tags) }}
</form>

Using the TagManager

Optionnaly, you can manage tags in a controller using the TagManager service.

<?php
    
    // Get the TagManager service
    $this->tagManager = $this->get('unifik_doctrine_behaviors.tag_manager');
    
    // Define a resource type (set to null if you want to use global tags)
    $resourceType = 'Unifik\BlogBundle\Entity\Article';
    
    // Load or create a new tag
    $tag = $this->tagManager->loadOrCreateTag('Smallville', $resourceType);

    // Load or create a list of tags
    $tagNames = $this->tagManager->splitTagNames('Clark Kent, Loïs Lane, Superman'));
    $tags = $this->tagManager->loadOrCreateTags($tagNames, $resourceType);

    // Add a tag on your taggable resource..
    $this->tagManager->addTag($tag, $article);

    // Add a list of tags on your taggable resource..
    $this->tagManager->addTags($tags, $article);

    // Remove a tog on your taggable resource..
    $this->tagManager->remove($tag, $article);

    // Save tagging..
    // Note: $article must be saved in your database before (persist & flush)
    $this->tagManager->saveTagging($article);

    // Load tagging..
    $this->tagManager->loadTagging($article);

    // Replace all current tags..
    $tags = $this->tagManager->loadOrCreateTags(array('Smallville', 'Superman'), $resourceType);
    $this->tagManager->replaceTags($tags, $article);

Tag-related queries

The Tag entity has a repository class, with two particularly helpful methods:

<?php

    $tagRepo = $em->getRepository('UnifikDoctrineBehaviorsBundle:Tag');

    // Define a resource type (set to null if you want to use global tags)
    $resourceType = 'Unifik\SystemBundle\Entity\Section';
    
    // or
    $resourceType = $taggableEntity->getResourceType();

    // Find all article ids matching a particular query
    $ids = $tagRepo->getResourceIdsForTag($resourceType, 'footag');

    // Get the tags and count for all articles
    $tags = $tagRepo->getTagsWithCountArray($resourceType);
    foreach ($tags as $name => $count) {
        echo sprintf('The tag "%s" matches "%s" articles', $name, $count);
    }
    
    // Get the related blog Article having common tags with a Section entity
    // This method creates a QueryBuilder with a "resource" alias, which in this case is "Unifik\BlogBundle\Entity\Article"
    $queryBuilder = $tagRepo->getResourcesByTagsQueryBuilder($section->getTags(), 'Unifik\BlogBundle\Entity\Article');
    $queryBuilder->orderBy('resource.updatedAt', 'DESC');
    
    $articles = $queryBuilder->getQuery()->getResult();
