I have this template in twig : 

{% form_theme form _self %}  

{% block body %}

<div class="container">
    <h1>creer une nouvelle annonce</h1>

    {{ form_start(form) }}

        {{ form_widget(form) }}

        <button type="submit" class="btn btn-primary">créer la nouvelle annonce</button>

    {{ form_end(form, {'render_rest': false}) }}

</div>

{% endblock %}

{% block form_row %}

<pre>
    {{ dump() }}
</pre>
<div class="form-group">
    {{ form_label(form) }}
    {{ form_widget(form) }}
</div>

{% endblock %}

and this is the output of the dump function in my chrome:

I can't reply to the cmd when it asks for an input (solved)

I am just starting to learn how to use Symfony 4 and I have a problem. Sometimes when I use the command terminal, it interacts with me (like it asks for the name of a property of an entity), the problem is that I can never reply, it always stops and aborts the interaction immediately.

Edit: It still doesn't work but I wrote the option -v and it gave me the thing on the next picture/link. Does somebody know what it means? Here is the command display with -v

Edit(2): I searched inside the code where the error appeared and I saw this above the function where the RuntimeException come from:

/**
 * Asks the question to the user.
 *
 * @return bool|mixed|string|null
 *
 * @throws RuntimeException In case the fallback is deactivated and the response cannot be hidden
 */

Does somebody know what it means?

Edit(Solved): as you may see in the comment section, I solved my problem by using php version 7.3.12 instead of 7.4

Symfony 4, get Logger, get Doctrine, get Rabbit out of the controller

In Symfony 3.3 on the controller I could do:

$sendEmailManager = new SendEmailManager($this->container);

And in the Manager:

private $ container;
public function __construct(ContainerInterface $ container) {
$this->container = $container;
}

I could use this in all methods:

$logger = $ this->container->get('logger');
$em = $this->container->get('doctrine')->getManager();
$container->get('old_sound_rabbit_mq.producer_email_text_producer')->publish(json_encode($ dataToRabbit));

How can I do this in Symfony 4.4?

symfony route import with allowable null prefix does not work

$

when importing routes from a resource file with a prefix, symfony will not match a valid route with an empty prefix unless the URL has a double / in it (//).

How to reproduce Given this setting:

web:
  resource: '_routes.yaml'
  prefix: /{route_prefix?}
  requirements:
    route_prefix: valueA|valueB

and _routes.yaml:

product_list:
  path: '/brands/{brand_name}/{id}.html'
  controller: App\Controller\Brand\ProductController::index

the router will match: /valueA/brands/{brand_name}/{id}.html and /valueB/brands/{brand_name}/{id}.html but will not match/brands/{brand_name}/{id}.html unless you provide the URL like this: //brands/{brand_name}/{id}.html

Is it really a bug or something I do not understand?

How to prevent user from being unauthenticated after dynamic password change

December 9, 2019, 5:32 am
$

The problem is when I change user password in my database while I'm logged in, my user becomes unauthenticated after refreshing the page.

It causes too many redirects error in my browser because my root controller is trying to redirect to controller which is protected by @Security("is_granted('ROLE_ADMIN')") annotation.

SecurityController.php

/**
 * @Route("/", name="app_login")
 */
public function login(AuthenticationUtils $authenticationUtils): Response
{
    // (...)
    return $this->redirectToRoute('admin');
}

AdminController.php

/**
 * @Route("/admin", name="admin")
 * @Security("is_granted('ROLE_ADMIN')", message="403 Access denied")
 */
public function index()
{
    // (...)
}

After refreshing /admin view (or every other view) it fails to authenticate current user due to @Security annotation and it falls back to root controller when the infinite redirect loop begins.

How to prevent Symfony from changing user status on password change while being logged in?

How to keep a pre-existing table unchanged when using migrations in Symfony?

I need that Symfony/migration/Doctrine to leave my table untouched. Don't touch her structure at all!

I have a pre-existing table (a legacy database) with the id field defined like this: "id bigint NOT NULL DEFAULT nextval('configuracoes_seq'::regclass),"

When I define ORM (Doctrine) like this:

 * @ORM\Column(name="id", type="bigint", nullable=false, options={"default":"nextval('configuracoes_seq'::regclass)"})
 * @ORM\Id 
 * @ORM\GeneratedValue(strategy="IDENTITY")
 * @ORM\SequenceGenerator(sequenceName="configuracoes_seq", allocationSize=1, initialValue=1)

The make:migration changes my table (I don't want it to change) like this:

$this->addSql('DROP SEQUENCE configuracoes_seq CASCADE');
$this->addSql('ALTER TABLE configuracoes ALTER id SET');

When I define ORM (Doctrine) like this:

 * @ORM\Column(name="id", type="bigint", nullable=false, options={"default":"nextval('configuracoes_seq'::regclass)"})
 * @ORM\Id 
 * @ORM\GeneratedValue(strategy="SEQUENCE")
 * @ORM\SequenceGenerator(sequenceName="configuracoes_seq", allocationSize=1, initialValue=1)

The make:migration changes my table (I don't want it to change) like this:

    $this->addSql('ALTER TABLE configuracoes ALTER id SET DEFAULT nextval(\'configuracoes_seq\'::regclass)');
    $this->addSql('ALTER TABLE configuracoes ALTER id DROP DEFAULT');

Symfony 4 Accessing Swift_Mailer in Service

I have been looking at the Symfony 4.1 documentation on using the Swift_mailer. However, it appears the documentation is only assumed it being used in the Controller classes. I'm trying to create a Service with some reusable functions that send email.

I created a EmailService.php file in my service directory. When creating a new instance of this service, it quickly throws and error:

"Too few arguments to function App\Service\EmailService::__construct(), 0 passed in *MyApp\src\Controller\TestController.php on line 33 and exactly 1 expected"

I'm not sure how to pass \Swift_Mailer $mailer into the __construct correctly? I have auto wiring enabled in the services.yaml, so i'm not sure what I need to do differently?

class EmailService
{
    private $from = 'support@******.com';
    private $mailer;

    public function __construct(\Swift_Mailer $mailer)
    {
        $this->mailer = $mailer;
    }

How do I pass the \Swift_Mailer into this EmailService construct?

I tried adding this to my config\services.yaml with no success:

App\Service\EmailService:
        arguments: ['@mailer']

I try to run a simple Symfony 4 project on a docker container. I have tested regular PHP scripts, and they work very well. But, with Symfony project, the execution gets ridiculously slow. For example, a page without any significant content takes 5-6 seconds.

I have attached the screenshots from Symfony's performance profiler.

            'entity' => CustomAddress::class,

        if ($table->isCallback()) {
            return $table->getResponse();
        }

        return $this->render('sales_request/add_custom_address.html.twig', ['datatable' => $table]);

Also, in my twig template

        $(function() {
            $('#addresses').initDataTables({{ datatable_settings(datatable) }}, { searching: true });
        });

The datatable works fine, sorting is working etc, but I dont see the search input field.How should I configure it to display it?

Symfony 4: I decorated UrlGeneratorInterface, but it's not used, it uses CompiledUrlGenerator instead

I decorated UrlGeneratorInterface 

app.decorator.url_generator:
    class: App\CoreBundle\Routing\Extension\UrlGenerator
    decorates: Symfony\Component\Routing\Generator\UrlGeneratorInterface
    arguments: ['@app.decorator.url_generator.inner']

but it's not used in cases where some bundle in example executes $this->generator->generate(), and I tracked what Symfony does through XDebug and CompiledUrlGenerator is used instead. I can see where this happens, namely in Symfony\Component\Routing\Router in getGenerator it specifically checks for CompiledUrlGenerator::class. But I don't want to override vanilla Symfony code. How am I supposed to override/decorate/extend which class in order for mine to be chosen always, as I have special parameters I need to add to the path. Thank you in advance!

Symfony 4 / Doctrine 2 Can't execute method of Entity a second time

Searched the internet for a answer but I can't get any information regarding this issue. (The names are fictional.)

I am working on a complex webapplication and I am trying to use a 'customSession' entity with a field called 'humanData' and its saved as a blob. With the method getHumanData() I can get the data from the entity. But if I execute the method a second time the data is null.

Entity: customSession

    /**
     * @ORM\Entity(repositoryClass="App\Repository\customSessionRepository")
     */
    class customSession {

          /**
           * @ORM\Column(type="blob", nullable=true)
           */
          private $humanData;

  public function getHumanData() {
    if (is_resource($this->humanData)) {
      $humanData = stream_get_contents($this->humanData);
      return $humanData;
    } else {
      return $this->humanData;
    }
  }

  public function setHumanData($humanData): self {
    $this->humanData= json_encode($humanData);
    return $this;
  }

    }

Testscript:

$first = json_decode($this->customSession->getHumanData());
$second = json_decode($this->customSession->getHumanData());
dump($first);
dump($second);
die();

Output $first:

Test.php on line 11:
{#6514
  +"gender": "M"
  +"firstName": "Test1"
  +"namePrefix": ""
  +"lastName": "Test2"
  +"initials": "TT"

  +"address": "Test 3"
  +"zipcode": "6745"
  +"place": "Amsterdam"
  +"country": "Nederland"
  +"countryCode": "NL"
}

Output $second:

Test.php on line 12:
null

Does anyone know why this is? And how to avoid it? I need the data in several places.

Guard Authenticator in Symfony 4

I am creating a simple login authentication system in Symfony 4 and using security component Guard. My FormLoginAuthenticator is following: 

<?php
namespace App\Security;

use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpFoundation\RedirectResponse;
use Symfony\Component\Routing\RouterInterface;
use Symfony\Component\Security\Core\Encoder\UserPasswordEncoderInterface;
use Symfony\Component\Security\Core\Exception\BadCredentialsException;
use Symfony\Component\Security\Core\Exception\AuthenticationException;
use Symfony\Component\Security\Core\User\UserInterface;
use Symfony\Component\Security\Core\User\UserProviderInterface;
use Symfony\Component\Security\Core\Authentication\Token\TokenInterface;
use Symfony\Component\Security\Guard\Authenticator\AbstractFormLoginAuthenticator;
use Symfony\Component\Security\Core\Security;

class FormLoginAuthenticator extends AbstractFormLoginAuthenticator
{
    private $router;
    private $encoder;

    public function __construct(RouterInterface $router, UserPasswordEncoderInterface $encoder)
    {
        $this->router = $router;
        $this->encoder = $encoder;
    }

    public function getCredentials(Request $request)
    {
        if ($request->getPathInfo() != '/login_check') {
          return;
        }

        $email = $request->request->get('_email');
        $request->getSession()->set(Security::LAST_USERNAME, $email);
        $password = $request->request->get('_password');

        return [
            'email' => $email,
            'password' => $password,
        ];
    }

    public function getUser($credentials, UserProviderInterface $userProvider)
    {
        $email = $credentials['email'];

        return $userProvider->loadUserByUsername($email);
    }

    public function checkCredentials($credentials, UserInterface $user)
    {
        $plainPassword = $credentials['password'];
        if ($this->encoder->isPasswordValid($user, $plainPassword)) {
            return true;
        }

        throw new BadCredentialsException();
    }

    public function onAuthenticationSuccess(Request $request, TokenInterface $token, $providerKey)
    {
        $url = $this->router->generate('welcome');

        return new RedirectResponse($url);
    }

    public function onAuthenticationFailure(Request $request, AuthenticationException $exception)
    {
       $request->getSession()->set(Security::AUTHENTICATION_ERROR, $exception);

       $url = $this->router->generate('login');

       return new RedirectResponse($url);
    }

    protected function getLoginUrl()
    {
        return $this->router->generate('login');
    }

    protected function getDefaultSuccessRedirectUrl()
    {
        return $this->router->generate('welcome');
    }

    public function supportsRememberMe()
    {
        return false;
    }
}

But it is showing following error:

(1/1) FatalErrorException Error: Class App\Security\FormLoginAuthenticator contains 1 abstract method and must therefore be declared abstract or implement the remaining methods (Symfony\Component\Security\Guard\AuthenticatorInterface::supports)

Could you please give me any clue which abstract method of this class is causing this error ?

Symfony Messenger / RabbitMQ detecting requed messages

If consuming message fails message is re-queued with a delay by default. Is there a way to add a counter to a message so I could know if message is on its last attempt?

This is desired behavior:

First attempt:

App\Message\Message {
  body: array:2 [
    "id" => 2
    "alias" => "some_alias",
    "attempt" => 0,
  ]
}

First retry:

App\Message\Message {
  body: array:2 [
    "id" => 2
    "alias" => "some_alias",
    "attempt" => 1,
  ]
}

Second retry:

App\Message\Message {
  body: array:2 [
    "id" => 2
    "alias" => "some_alias",
    "attempt" => 2,
  ]
}

Third retry:

App\Message\Message {
  body: array:2 [
    "id" => 2
    "alias" => "some_alias",
    "attempt" => 3,
  ]
}

I have a problem with a query. I have 3 entities define like below :

  • Category entity
class Category
{
    /**
     * @ORM\Id()
     * @ORM\GeneratedValue()
     * @ORM\Column(type="integer")
     */
    private $id;

    //...

    /**
     * @var Product[]
     *
     * @ORM\ManyToMany(targetEntity="App\Entity\Product", mappedBy="categories")
     */
    private $products;

    //...
}
  • Product entity
class Product
{
    /**
     * @var int
     *
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="IDENTITY")
     * @ORM\Column(type="integer")
     */
    private $id;

    //...

    /**
     * @var Collection
     *
     * @ORM\ManyToMany(targetEntity="App\Entity\Category", inversedBy="products")
     * @ORM\JoinTable(name="product_category",
     *   joinColumns={
     *     @ORM\JoinColumn(name="id_product", referencedColumnName="id", nullable=false)
     *   },
     *   inverseJoinColumns={
     *     @ORM\JoinColumn(name="id_category", referencedColumnName="id", nullable=false)
     *   }
     * )
     */
    private $categories;

    /**
     * @var Provider
     *
     * @ORM\ManyToOne(targetEntity="App\Entity\Provider", inversedBy="products")
     * @ORM\JoinColumns({
     *   @ORM\JoinColumn(name="id_provider", referencedColumnName="id", nullable=false)
     * })
     */
    private $provider;

    //...
}
  • Provider entity
class Provider
{
    /**
     * @var int
     *
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="IDENTITY")
     * @ORM\Column(type="integer")
     */
    private $id;

    //...

    /**
     * @var Product[]
     *
     * @ORM\OneToMany(targetEntity="App\Entity\Product", mappedBy="provider", orphanRemoval=true, cascade={"all"})
     */
    private $products;

    //...
}

I want to query all products categories manage by a provider. So i try this :

class CategoryRepository extends ServiceEntityRepository
{
    public function __construct(ManagerRegistry $registry)
    {
        parent::__construct($registry, Category::class);
    }

    public function findByProvider(Provider $provider)
    {
        $qb = $this->createQueryBuilder('c');

        return $qb->leftJoin('c.products', 'p')
                  ->addSelect('p')
                  ->andWhere('p.provider = :provider')
                  ->setParameter('provider', $provider)
                  ->addOrderBy('c.name')
                  ->getQuery()
                  ->getResult();
    }
}

But i always have an empty result despite the fact that a provider have many products. Please how should i achieve this query. Thank you

How to prevent Symfony 4 service override?

December 10, 2019, 10:28 am

I have base /config/services.yaml which stores many services in my Symfony 4.3 project. For example:

My\Namespace\Service:
  - '@My\Namespace\Dependency'

For my test purposes, I have config/test/test_services.yaml where I store services with 'test.' prefix to test private services, making them public in test env.

One of the services, declared in test_services.yaml has no prefix. It is identical by its name (FQCN) to another one defined in services.yaml. They have different constructor arguments of the same type.

Test one (/config/test_services.yaml) has mocked dependencies returning fixtures data:

My\Namespace\Service:
  - '@My\Namespace\MockedDependency'

Is there a way to prevent service override to not replace mocked service with real one during test execution in test env?

Symfony TwigBundle not loading any custom extensions

December 10, 2019, 4:31 pm

I am working on updating Zikula from Symfony 3 to Symfony 4 (I'm working specifically in this PR at the moment). Part of this is removing Symfony's old templating mechanism and switching entirely to Twig. In the process I am running into a very unusual problem: None of the custom Twig extensions in the included Bundles or the pseudo bundles (they're just Bundles named Modules) are loaded and available in templates.

Yes, the extensions class are autowired and autoloaded and yes they are available - i.e. they are listed in bin/console debug:container and specifically if I do something like 

me% bin/console debug:container AdminExtension

Information for Service "Zikula\AdminModule\Twig\Extension\AdminExtension"
==========================================================================

 ---------------- -------------------------------------------------- 
  Option           Value                                             
 ---------------- -------------------------------------------------- 
  Service ID       Zikula\AdminModule\Twig\Extension\AdminExtension

  Tags             twig.extension

  Synthetic        no                                                
  Lazy             no                                                
  Shared           yes                                               
  Abstract         no                                                
  Autowired        yes                                               
  Autoconfigured   yes                                               
 ---------------- -------------------------------------------------- 

 ! [NOTE] The "Zikula\AdminModule\Twig\Extension\AdminExtension" service or alias has been removed or inlined when the  
 !        container was compiled.

This clearly shows that not only is the service properly autowired, but it is also tagged correctly.

If I do bin/console debug:twignone of the custom extensions are listed (at the top with functions, filters, etc). I even tried to step through the TwigBundle Compiler process and I am quite sure the callable are being included there.

Do you have any idea what the problem is or how I might troubleshoot it?
