Serializing Entity Relation only to Id with JMS Serializer

Question

I\'m trying to serialize a entity relation with JMS Serializer.

Here is the Entity:

class Ad
{ 

    /**
     * @Type(\"string\")
     * @Groups({\"manag         


        

Answer 1

You can use @Type and @Accessor annotations:

/**
 * @Type("string") 
 * @Accessor(getter="serializeType",setter="setType") 
 */
protected $type;
public function serializeType()
{   
  return $this->type->getId();
}
