[NelmioApiDocBundle] how to register models without annotations or attributes?

config/packages/nelmio_api_doc.yaml:

```

nelmio_api_doc:

    models:

        use_jms: true

        names:

            - { alias: ExamType, type: StudentBundle\Form\ExamType }

            - { alias: User, type: App\Entity\User }

            - { alias: Pager, type: ApiBundle\Model\Pager }

``` 

[php] code changes does not applied, how to fix?

If you make changes in php code and don't see that they work, like code remains the same, do this

 be sure your php.ini configuration `opcache.validate_timestamps=0` ,  not 1. It can be in dev mode when you try to optimize Symfony project workflow.

[SyliusResourceBundle] how to pass model into controller?

 Sometimes you don't need to use model instead of entity, and then save some data into entity and persist it. It means you cannot use it in Sylius ResourceControllers, because your model must implement ResourceInterface, create dedicated ResourceController, Repository, Manager, and model cannot do it.

If you want it, this means you doing it wrong, because it violated CRUD principles. The best solution is to use Symfony Data Transformers https://symfony.com/doc/current/form/data_transformers.html , add it to your form, implement transform() method, where it will create your model/DTO object from entity, and reverseTransform(), where DTO will be converted into Entity object.

[Doctrine] how to replace Many-To-Many to three entities

When you need to put new field/database columns into Many-To-Many, relationship, you will need to switch to intermediate entity. In my case it is StudentKlass.

Imagine three entities: Team - StudentTeam - Student

use Doctrine\ORM\Mapping as ORM;

class Team {
    /**
     * @ORM\OneToMany(targetEntity=StudentTeam::class, mappedBy="team", cascade={"persist"})
     */
    private $studentTeams;
    
    public function __construct() {
        $this->studentTeams = new ArrayCollection();
    }
    ...
}

class StudentTeam {
    /**
     * @ORM\ManyToOne(targetEntity=Student::class, inversedBy="teams")
     * @ORM\JoinColumn(name="student_id", referencedColumnName="id")
     */
    private $student;

    /**
     * @ORM\ManyToOne(targetEntity=Team::class, inversedBy="studentTeams")
     */
    private $team;
    ...
}

class Student {
    /**
     * @ORM\OneToMany(targetEntity=StudentTeam::class, mappedBy="student")
     */
    private $teams;
    private $name;
    private $email;
    ...

} 

Also don't forget to create getters, adders & removers!

You can use example how to use it in Symfony forms, which has example how to use nested forms:

class TeamType extends AbstractType {
    public function buildForm(FormBuilderInterface $builder, array $options) {
        $builder
            ->add('studentTeams', CollectionType::class, [
                'entry_type' => TeamStudentType::class,
                'allow_add' => true,
                'allow_delete' => true,
                'by_reference' => false,
            ]);
    ...
}

class TeamStudentType extends AbstractType {
    public function buildForm(FormBuilderInterface $builder, array $options) {
        $builder
            ->add(
                $builder
                    ->create('student', FormType::class, [
                        'data_class' => Student::class,
                    ])
                    ->add('email', TextType::class)
                    ->add('name', TextType::class)
            )
        ;
    }
}
}

[Symfony] "FormType too few arguments passed 0, 1 argument needed" fix

It can be not only FormType, also can be any your custom form type. 

It can be when you moved your form into new namespace/bundle, but did not registered services in it. 

1. don't forget that your form should extend Symfony\Component\Form\AbstractType;
2. add new bundle namespace in composer.json
3. Create bundle extension file in ./DependencyInjection/FooExtenstion like this https://symfony.com/doc/current/bundles/extension.html
4. add this into your bundle services.yaml:

services:

    # default configuration for services in *this* file

    _defaults:

        autowire: true      # Automatically injects dependencies in your services.

        autoconfigure: true

    FooBundle\:

        resource: '../src/'

        exclude:

            - '../src/DependencyInjection/'

            - '../src/Entity/'

            - '../src/Kernel.php'

            - '../src/Tests/'

        5. run php bin/console cache:clear

how to fix "keypair size should be SODIUM_CRYPTO_BOX_KEYPAIRBYTES bytes"

 Check that you copied private key, instead of public key. Because their length differs from each other

[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,

...

[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

How to create CollectionType with empty one element

 Add 'data' => [''] (not 'empty_data') to the Collection type form configuration.

[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

how to load BazingaJsTranslationBundle without ajax requests (+ inside Vue components)

1. Install it as in bundle readme.md
2. run `php bin/console bazinga:js-translation:dump public/js --format=js`
   
3. add in your main template tag: <html lang="{{ app.request.locale|split('_')[0] }}">
4. add in your js file:
   global.Translator = require('../public/bundles/bazingajstranslation/js/translator.min');
   require('../public/js/translations/messages/ru.js');
5. if you need also access Translator via Vue, add it in your Vue initialization file:
   Vue.prototype.$t = Translator;
   And use it in your template like this: {{ $t.trans('common.save') }}

[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 }

[Sylius] Argument 1 passed to Sylius\Component\Grid\Definition\Filter::setTemplate() must be of the type string, null given fix

 put `grid: <gridname>` into your route like this:

tests:
    path: /tests
    defaults:
        _controller: app.controller.test:indexAction
        _sylius:
            template: tests/index.html.twig
            grid: app_test

Encore does not load css/sass files in tsx/js files fixed

 If you installed @types/node-sass, enabled enableSassLoader in webpack.config.js, ran yarn add sass-loader@^8.0.0 node-sass --dev , do not forget to add {{ encore_entry_link_tags('main') }} like this (for example in templates/base.html.twig:
