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

Alternatively, you can @inline $country which will serialize its properties into the parent relation. Then you can @Expose the Country $id and set its @SerializedName to "country". Unlike Virtual properties, both serialization and deserialization will work for inline properties.

For this to work, you need to use the @ExclusionPolicy("All") on each class and judiciously @Expose the properties that you need in any of your groups. This is a more secure policy anyways.

/**
 * @ExclusionPolicy("All")
 */
class Ad
{ 

    //...


    /**
     * @Type("Acme\SearchBundle\Entity\Country")
     * 
     * @Expose()
     * @Inline()
     * @Groups({"manage"})
     *
     * @var \Acme\SearchBundle\Entity\Country
     */
    private $country;


    //...

}

/**
 * @ExclusionPolicy("All")
 */
class Country
{

    //...

    /**
     * Get id
     *
     * @Expose()
     * @Groups({"manage"})
     * @SerializedName("country")
     * @return string 
     */
    public function getId()
    {
        return $this->id;
    }
}
