Serializing traits with JMSSerializer and YAML

[benatespina]

When trying to serialize a model that uses traits, JMSSerializer does not serialize properties included by that trait. I am using yaml to configure the serializer but it seems that it's not working.

trait IdentityTrait
{

    protected $id;

    public function setId($id)
    {
        $this->id = $id;

        return $this;
    }

    public function getId()
    {
        return $this->id;
    }
}

class OurClass {
   use IdentityTrait;

   protected $test;

   public function getTest() {
       $this->test;
   }
}

JMSSerializerBundle is used and the following yaml is located in Resources/config/serializer/Model.Traits.IdentityTrait.yml

MyProject\Component\Core\Model\Traits\IdentityTrait:
    exclusion_policy: NONE
    properties:
    id:
        expose: true

And the OurClass configuration is located in Resources/config/serializer/Model.OurClass.yml

 MyProject\Component\Core\Model\OurClass:
     exclusion_policy: NONE
     properties:
         test:
             expose: true

Some code has been ignored to focus on the problem.

Maybe the trait file name is incorrect?

I have the same problem I am using KnpDoctrinebehaviors for my translations and jms does not serialize my translated fields. Did you find a workaround ? @benatespina

So have anyone solution for this?

See this issue: #102

I'm using jms/serializer version 1.4.* and it's working fine. Couldn't find in the changelog which version added this feature, but upgrading to a newer version than 1.0.0 helps.

I'm having the same issue (version 1.1.0).
@stephanvierkant, you say that using version 1.4.* is working but this version doesn't seem to even exist.
Could you give more inputs please ?

[stephanvierkant]

@yanict I'm using version 1.4.2 of jms/serializer and version 1.1.0 of jms/serializer-bundle. Please note the difference between the library (serializer) and the bundle that implements it (serializer-bundle).

Hello, I'm having trouble with this feature too.
Shall the configuration of the serialization be inserted in the hosting entity like in this example:

Resources/config/serializer/Model.OurClass.yml

MyProject\Component\Core\Model\OurClass:
    exclusion_policy: NONE
    properties:
        test:
            expose: true
        id:
            expose: true

Or is it possible to define the serialization elswhere, and how? I tried another file like @benatespina `but it seems never called

Metadata are per-class when using YAML or XML, defining metadata for a trait will not work.
You have to define your properties inside the metadata file for the class that is using the trait.
