Symfony Rest Controller Limiting serialization depth - php

Question

I have entity bit and relation ManyToMany developer, for developer I use * #Groups({"for_project"}) and when I use this anotation, in response not see fields developer, I look documentation and see * #MaxDepth(2) and use this but still have null. Why ?

SOLVED
I understand, need add * #Groups({"for_project"}) for fields entity developer
but when I deleted #MaxDepth I still have fields entity developer, why need #MaxDepth ?
I understand, when use without #MaxDept, we have maximum depth for relation fields, Example I have entity Bit, bit have Developer and developer have User, if I want visible fields entity User I need add #MaxDept(3) for field developer in entity Bit

Answer 1

when use without #MaxDept, we have maximum depth for relation fields, Example I have entity Bit, bit have Developer and developer have User, if I want visible fields entity User I need add #MaxDept(3) for field developer in entity Bit
in action:
return View::create()
->setStatusCode(200)
->setData($bits)
->setSerializationContext(
SerializationContext::create()
->enableMaxDepthChecks()
->setGroups(array("for_project"))
);
and in response
[
{
"id": 501,
"created": "2015-11-30T17:49:19+0200",
"developer_id": {
"id": 201,
"rate": 0,
"user": [
{
"first_name": "Ivan",
"last_name": "Shuba"
}
]
},
"rate": 4,
"comment": "fsefse"
}
]
and Entity
class Bit
{
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
* #Expose()
* #Groups({"for_project"})

private $id;
/**

private $created;
/**
* #var datetime $updated

private $developerId;
class Developer
{

Answer 2

This works for me using fos rest version: 2* and JMS serializer version: 3*
return $this->view($data)->setContext((new Context())->enableMaxDepth());
