[JMS serializer] how to set naming strategy

     public function serialize($object, array $serializationGroups)

    {

        $serializer = SerializerBuilder::create();

        $serializer->setPropertyNamingStrategy(new SerializedNameAnnotationStrategy(new IdenticalPropertyNamingStrategy()));

        $serializer->addMetadataDir($this->configDir . "/serializer", 'App\Entity');

        $serializer->setCacheDir($this->cacheDir . "/jms_serializer");

        $serializer = $serializer->build();

        $group = new GroupsExclusionStrategy($serializationGroups);

        $context = SerializationContext::create();

        $context->addExclusionStrategy($group);

        return $serializer->serialize($object, 'json', $context);

    }

It will make JSON string where property field is camelCased instead of Snake_cased. I highly recommend to use 'App\Entity' in addMetadataDir() because by default in Symfony jms_serializer.yaml config is set 'namespace_prefix' in metadata node, and without 'App\Entity' argument YML/XML entity configs won't work. It is also example how to customize Serializer parameters manually with SerializerBuilder without framework config.

[Symfony] Cannot read index 'email' from object of type App\Entity\User because it doesn't implement \ArrayAccess

 Its because PropertyAccessor thinks form is an array. To change it, set form data_class. For example in your form Type:

public function configureOptions(OptionsResolver $resolver)

    {

        $resolver

            ->setDefaults([

                'data_class' => User::class,

[behat] chromedriver cannot call send on null fix

 When you have error like this:

Fatal error: Call to a member function waitForLoad() on null (Behat\Testwork\Call\Exception\FatalThrowableError

Add this into your context:

if ($this->getSession()->isStarted() === false) {

            $minkSession->start();

}

[Symfony] Cannot login at Test environment - fix (in Behat)

When you trying to login in Test env, and it does not show any error (you was returned on login form again), and you does not have anything in logs, except Guard authenticator does not support the request. {"firewall_key":"main","authenticator":"App\\Security\\AppAuthenticator"}, you can try this.

 I removed lines:

 session:

        storage_id: session.storage.mock_file

in config/packages/test/framework.yaml and it worked

[Sylius] GridHelper::renderGrid() must be an instance of Sylius\Component\Grid\View\GridView, instance of Pagerfanta\Pagerfanta - how to fix

 It means you forgot to put `grid: gridname` into your route configuration. For example:

admin_user_index:

    path: /users

    defaults:

        _controller: app.controller.user::indexAction

        _sylius:

            template: "@AdminBundle/grid/index.html.twig"

            grid: admin_user

[Symfony] how to modify data_class object setting logic

 When you need extra manipulations to object data population in form (for example, you need to resolve whether is entered user email is already registered and put existing user object or it needs to create a new user), you might want to set data_class with closure, but there isn't such option.

The right way is to use https://symfony.com/doc/4.4/form/data_mappers.html Data Mappers

[Numberformatter] how to show plus sign after decimal number?

 If you need to show number for example "10.000+", where plus is in suffix, write:

$fmt = new NumberFormatter('es_ES', NumberFormatter::DECIMAL);
$fmt->setTextAttribute(NumberFormatter::POSITIVE_SUFFIX, '+');
$result = $fmt->format(10000);

Also if you use `NumberFormatter::POSITIVE_PREFIX` instead of `NumberFormatter::POSITIVE_SUFFIX`, you will get "+10.000".

[JMSSerializer] default serialization group are ignored fix

 If your default serialization group not working (does not ignore fields which should be shown only with specific group, not Default), check that \JMS\Serializer\Exclusion\GroupsExclusionStrategy is added into \JMS\Serializer\Context at  \JMS\Serializer\GraphNavigator::accept() method.

If you are using Sylius (or standalone bundles), it occurs when \FOS\RestBundle\Serializer\JMSSerializerAdapter does not add GroupsExclusionStrategy. You can fix it with adding serialization_groups: [Default] like this:

api_building_show:

    path: /exam/{id}

    methods: [GET]

    defaults:

        _controller: app.controller.building:showAction

        _sylius:

            serialization_groups: [Default]

[FOSRestBundle] Showing custom Exception message no working fix

 If ./config/packages/fos_rest.yaml:

fos_rest:

    exception:

        messages:

            Symfony\Component\HttpKernel\Exception\HttpException: true

for you too, you can inject this service manually like this in services.yaml:

fos_rest.exception.messages_map:

        class: FOS\RestBundle\Util\ExceptionValueMap

        public: false

        arguments:

            - { Symfony\Component\HttpKernel\Exception\AccessDeniedHttpException: true }
