serializer doesn't serialize traits

[ghost]

Hey,

thanks for this awesome bundle.

I've noticed that serializer doesnt serialize traits. I've this is my entity:

<?php

namespace BusinessBundle\Entity\Acl;

use Symfony\Component\Validator\Constraints as Assert,
    Symfony\Bridge\Doctrine\Validator\Constraints\UniqueEntity;

use FOS\UserBundle\Model\User as BaseUser;

use Doctrine\ORM\Mapping as ORM;

use Gedmo\Timestampable\Traits\TimestampableEntity;

use JMS\Serializer\Annotation as Serialize;

/**
 * @Serialize\ExclusionPolicy("all")
 */
class User extends BaseUser
{
    /**
     * Hook timestampable behavior
     */
    use TimestampableEntity;

    /**
     * @var \DateTime $createdAt
     *
     * @Serialize\Expose
     * @Serialize\Type("DateTime")
     * @Serialize\Since("0.15.0")
     * @Serialize\Groups({"acl"})
     */
    protected $createdAt;

    ....
}

When serializing this, I get

{
    "user":{
        "email": "[email protected]",
        "last_login": "2016-09-07T14:04:10+0200",
        "name": "Christian",
        "created_at": null, // it's null :(
        "newsletter": true,
        "ip_address": "192.168.56.1",
        "locale": "de",
        "country": "DE"
    }
}

In the database the value of created_at field is 2016-09-06 21:21:43. Is there anything I'm doing wrong or is it just not possible?

In the database the value of created_at field is 2016-09-06 21:21:43.

what is the filed value when you get it using a getter? getCreatedAt() as example

BTW, https://github.com/Atlantic18/DoctrineExtensions/blob/master/lib/Gedmo/Timestampable/Traits/TimestampableEntity.php already creates the $createdAt property.

Can this block the "Timestampable" behavior? making it null...

Ahhh, I just was missing an @ORM\Column(type="datetime") annotation at that field. It's working like a charm. Thanks for the help.

Can this block the "Timestampable" behavior?

Yeah, but then I have no possibilities to serialize it via annotations. So I think, I have to override this field.

[goetas]

I will just not use the trait :)

[ghost]

Hmm....are there better ways without writing code?

[goetas]

I mean, I will just copy/paste the content of the trait. Traits are just an "elegant" way of copy/paste

Not easy Re-use is the drawback of annotations.

Ok, thanks for your advice.
