Jmsserializerbundle: Filelocator is not called in Symfony 4

[mehdi-zarrin]

Hi,
I'm using Symfony 4 + FOSUserBundle for security reasons I have to hide some fields (email, password,..). For some reason, the metadata file locator is not called after I call the serialize method in a controller. Here is my configuration:

packages/jms_serializer.yaml

jms_serializer:
    visitors:
        xml:
            format_output: '%kernel.debug%'
    metadata:
        auto_detection: true
        directories:
            FOSUB:
                namespace_prefix: FOS\UserBundle
                path: "%kernel.root_dir%/serializer"

src/serializer/FOSUB/Model.User.yml

FOS\UserBundle\Model\User:
    exclusion_policy: ALL
    properties:
        firstName:
            expose: true

composer

jms/metadata                           1.6.0              
jms/parser-lib                           1.0.0              
jms/serializer                            1.13.0             
jms/serializer-bundle               2.4.2

seeing your config, your file should be named src/serializer/Model.User.yml instead of src/serializer/FOSUB/Model.User.yml

I tried that before but that did not solve my issue. By the way, I change just the way you said but still, Exclusion policy is not happening for me.

I have updated the docs about this issue right few days ago... can you check that you did all the things in https://github.com/schmittjoh/JMSSerializerBundle/commit/6f45a525d1872fc533c0f40103ce0dda2ba70e57 ?

See the \\ as example... 99% of the cases this kind of issues were always mis-configurations.

I think I follow the documentation exactly, but I still have the same issue, that may be related to Symfony 4, because as I was searching for a solution I noticed many people using SF4 have the same problem. here is my directory structure:

- src 
--- serializer 
----- FOSUB
-------- Model.User.yml

jms_serializer:
    visitors:
        xml:
            format_output: '%kernel.debug%'
    metadata:
        auto_detection: true
        directories:
            FOSUB:
                namespace_prefix: "FOS\\UserBundle"
                path: "%kernel.root_dir%/serializer/FOSUB"

I noticed that the issue was related to wrong way of calling the serializer:
instead of
$serializer = $this->get('jms_serializer');

I was doing :

$serializerBuilder = SerializerBuilder::create();
$serializerBuilder->setPropertyNamingStrategy(new \JMS\Serializer\Naming\IdenticalPropertyNamingStrategy());
$serializer = $serializerBuilder->build();

now it's fixed.
