symfony - How to print translatable data in sonata admin with DoctrineBehaviors from kpnlabs

Question

I'm just looking the good way to use DoctrineBehaviors by knplabs.

I have allready render a form in sonata admin bundle with the help of this bundle : https://github.com/a2lix/TranslationFormBundle

Now, i want to have my translated field in the admin list.

At this time, it's work with this method:

/**
 * @ORMEntity
 * @ORMTable(name="sport") 
 */

class Sport
{
...

    public function getNom(){
        return $this->translate()->getNom();
    }
}

It's work but, i have to remap all the translated field in the original entity. I'm pretty sure i'm missing something, particularly with the magic of the proxy translations.

UPDATE:

class Sport
{

    use KnpDoctrineBehaviorsModelTranslatableTranslatable;

    public function __call($method, $arguments)
    {
        return $this->proxyCurrentLocaleTranslation($method, $arguments);
    }   
    /**
     * @ORMColumn(type="integer")
     * @ORMId
     * @ORMGeneratedValue(strategy="AUTO")
     */
    private $id;

    // Need this method for the admin list template
    public function getNom(){
         return $this->translate()->getNom();
    }

    // Work even the precedent method not here, the proxy call work fine.
    public function __toString(){
         return $this->getNom();
    }
}

class SportTranslation
{
    use ORMBehaviorsTranslatableTranslation;

    /**
     * @ORMColumn(type="string", length=255)
     */
    protected $nom;

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

    /**
     * @param  string
     * @return null
     */
    public function setNom($nom)
    {
        $this->nom = $nom;
    }
}

Thanks for your fast reply @nifr! The proxy Method work in a controller (i try on the __toString Method of sport, it's work fine).

But the issue apparently coming from sonata admin bundle, i check the template code, don't know why it doesn't work.

I will keep the ugly method until i finda better solution.

At this time it's the only way to print value in the admin list template.

If i find something better i will update this post.

How to use KnpDoctrineBehaviors magic proxy translations

Given you have MyClass and MyClassTranslation following the naming convention ( translation class suffixed with Translation ).

Only the properties which don't need to be translated live in MyClass and all translatable properties live in MyClassTranslation.

Let's say the translatable property shall be description.

---

MyClass.php

Attention: Neither property description nor getters/setters for description in MyClass .... otherwise __call() won't be invoked properly!

class MyClass
{

    use KnpDoctrineBehaviorsModelTranslatableTranslatable;

    public function __call($method, $arguments)
    {
        return $this->proxyCurrentLocaleTranslation($method, $arguments);
    }

    protected $nonTranslatableProperty;

    // ...

---

MyClassTranslation.php

use DoctrineORMMapping as ORM;

class MyClassTranslation
{
    use KnpDoctrineBehaviorsModelTranslatableTranslation;


    /**
     * @var string
     */
    protected $description;

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

    /**
     * @param string $description
     *
     * @return MyClassTranslation
     */
    public function setDescription($description)
    {
        $this->description = $description;

        return $this;
    }

---

Now calling MyClass::getDescription() will invoke the magic method __call() which will return the translation using the current locale because there is no getDescription() method in MyClass .

Solution:

You should remove all the translatable getters/setters/properties present in SportTranslation from your Sport class and instead add the magic __call() method.
