boolean values not serialized when value is null.

[schingeldi]

I have serialized entity with a boolean attribute. This attribute is not shown when the value is null, its only shown if it is 0. As I use it with FosRestBundle and a form, it is set to null automatically if I change it to "false".

Is there any possibility to show null values as false?

You'll need to write you own handler if you want to automatically make such
a conversion.

and if you want to show null values as null, you can enable the serialization of null values int he SerializationContext

Thanks, but where exactly to I configure this. Now I followed the documentation and did:

namespace Acme\AdBundle\Handler;

use JMS\Serializer\Context;
use JMS\Serializer\JsonSerializationVisitor;


class SerializationHandler {


public function serializeBooleanToJson( JsonSerializationVisitor $visitor, $bool, array $type, Context $context ){

    $context->setSerializeNull(true);

    if( $bool ) {
        return 'YES';
    }
    return 'NO';

}

}

And in services.xml:

<service id="acme.serialization_handler" class="Acme\AdBundle\Handler\SerializationHandler" public="false">
            <tag name="jms_serializer.handler" type="boolean" direction="serialization" format="json"
             method="serializeBooleanToJson" />
</service>

But it does not seem to call thehandler at all
