I have updated Symfony project (api platform) from 4.3 to 4.4, but now I receive this error in some POST/PUT requests:

I have some ManyToMany table relations. I'd like those to have a "created_at" field set when INSERT INTO.

Following Symfony and Doctrine Documentation, i tired this :

app/config/services_dev.yaml

[...]
    App\Event\Listener\ManyToManyListener:
        tags:
            - { name: doctrine.event_listener, event: onSchemaCreateTable }

app/src/Event/Listener/ManyToManyListener.php

[.....]

class ManyToManyListener implements EventSubscriber
{
    public function getSubscribedEvents()
    {
        return ['onSchemaCreateTable'];
    }

    public function onSchemaCreateTable(SchemaCreateTableEventArgs  $event)
    {
        $columns = $event->getTable()->getColumns();

        if (count($columns) <= 2 && !array_key_exists("created_at", $columns)) {
            $tableName = $event->getTable()->getName();
            $sql = "ALTER TABLE $tableName ADD COLUMN created_at TIMESTAMP(0) WITHOUT TIME ZONE NOT NULL DEFAULT CURRENT_TIMESTAMP;";
            $event->addSql($sql);
              //dump($sql);
        }
    }
}

I can dump my SQL code inside, it works.

I also tried this code (inside the if statement)

$event->getTable()->addColumn(
                "created_at",
                "datetime",
                ["default" => "CURRENT_TIMESTAMP"]
            );

This never execute the SQL statement. For example, while php bin/console doctrine:schema:update --dump-sql, I can't see my query.

Every time I run bin/console cache:clear --env=prod got an error Environment variable not found: "LOCALE" or any other variable. If a run it on the dev environment I wont see any error.

I can always run LOCALE=es_CO ./bin/console cache:clear --env=prod but I'll get an error for the next variable.

symfony/dotenv version is v4.3.2

It seems to be working when making requests via web server.

Not sure what else should be done.

I wish to set up a GraphQL API on a symfony 4 application, according to you between its two two solutions (overblog/GraphQLBundle vs ApiPlatform) which should I choose to build my API and why do you think?

Thanks

I have a Symfony4 app that is basically done and now am writing some tests for it. I'm trying to see if I can get a success http 200 from this controller route using this command vendor/bin/phpunit --debug tests/SampleTest.php

The page is protected by the default login form auth that symfony uses (debug below)

Using a PostAuthenticationGuardToken didn't work either. I'm all out of ideas

this is my first post so i'll try to be understandable.

I am starting with symfony, and there is a problem i can't resolve alone.

This is my controller, and I am working with WAMP. When my Url is "mysite.local", it work normally, and it show me what it should (thanks to the home() function). But when my Url is "mysite.local/hello", i have the following error.

Not Found

The requested URL was not found on this server.

Apache/2.4.41 (Win64) PHP/7.4.0 Server at mysite.local Port 80

I guess this is normal as i didn't created any file named "hello", but it's working in the formation i am following.

Could you help me please ? Thank you

<?php


namespace App\Controller;

use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;

use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;

class HomeController extends AbstractController
{
/**
 * @Route("/hello", name="hello")
 */

public function hello()
{
    return new Response("Bonjour ...");
}
/**
 *@Route("/", name="homepage");
 */

public function home(){
    $prenoms = ["Lior" => 17 , "Joseph" => 12, "Anne" => 55];
    return $this->render("home.html.twig",
        [
            'title' => "Bonjour a tous :)",
            'age' => "31 ",
            'tableau' => $prenoms,
        ]); 
}

I have a Symfony 4 application that uses Doctrine for all database access. The table in question has a number of columns that are defined with "NOT NULL".

All of the getter methods in the entity class are written such that they return an empty string if the current value is null

public function getApartment(): string
{
  return $this->apartment ?? '';
}

It is my understanding that Doctrine calls the entity's getter methods to retrieve the current values when persisting the object into the database.

I don't see how getters written like the one above can possibly result in null values, yet this error occasionally happens. Note that it doesn't happen all the time, only sometimes and I haven't spotted any sort of pattern yet.

In addition to the getters, several of the entity's field definitions are tagged with @Assert\NotBlank annotations so the Form component shouldn't return true from the isValid() method.

Here is a (slightly edited) example error from var/log/prod.log:

[2020-03-02 22:23:22] request.CRITICAL: Uncaught PHP Exception

As you can see, the only value that is not null is dateCreated. it is set via a method that is tagged with an @ORM\PrePersist annotation.

The action method only attempts to persist the object if the form has been submitted and is valid, meaning that all fields tagged with @Verify\NotBlank can not be blank.

$form->handleRequest( $request );
if( $form->isSubmitted() && $form->isValid())
{
  $em = $this->getEntityManager();
  $repository = $em->getRepository( FreeClassQuery::class );
  $em->persist( $classQuery );
  $em->flush();
  ...
}

I have a project with Symfony 4.4 and FosRestBundle. I'm trying to customize the exception handling by changing the json output. In this particular case I have a controller that receives a query string language param and it validates it's correct (en_GB, it_IT, etc...). So when I pass an incorrect language code I want it to be handled by my own controller. The exception is thrown but is catched by it never goes to my custom controller, seems like its directly Symfony who does the output. My fos_rest.yaml:

fos_rest:
  param_fetcher_listener: force
  exception:
    enabled: true
    exception_controller: 'AppBundle\Action\ExceptionAction'

My action controller:

    /**
     * @Route(
     *     "/api/v1/categories/{id}",
     *     name="get_category",
     *     methods={"GET"},

     * )

One thing that bothers me is I can write whatever I want in the exception_controller configuration option (like non-existent-controller) and the code doesn't fail witch makes me think that something is not plugged correctly. Any ideas why this is not working? Thanks a lot!

Hello devs when I try to connect with my login form ( when I submit the form ) it doesn't work and gives me the following error:

Notice: A non well formed numeric value encountered

so thank you in advance for your answers

so I use the symfony 4 security component for authentication.

Here's the code:

Controller:

<?php

namespace App\Controller ;

use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;
use App\Entity\User ;

//Class pour authentification
use Symfony\Component\Security\Http\Authentication\AuthenticationUtils ;


class SecurityController extends AbstractController
{

  /**
  * @Route("/login" , name="login")
  */
  public function login(AuthenticationUtils $authentication)
  {
    $error = $authentication -> getLastAuthenticationError();

    $lastUsername = $authentication -> getLastUsername();

    return $this -> render('Authentification/login.html.twig' ,[

      'error'  => $error,
      'last_username' => $lastUsername,
      ]) ;

  }

}

thank you in advance for your help (^_^)

When it comes to creating bundles, it's often necessary to support some configuration for the developers who'll use the bundle.

In this case, I need the configuration's value to support %someText%, without Symfony trying to resolve this value as parameter.

Example: Incorrect Configuration

my_bundle_name:
    my_configuration: '%someText%'

So, I figured, I'll have to escape the % (so it looks like %%) to make things work - resulting in the value %%someText%%.

If some parameter value includes the % character, you need to escape it by adding another % so Symfony doesn't consider it a reference to a parameter name [...]

Example: No Error, but Unexpected Result

my_bundle_name:
    my_configuration: '%%someText%%'

While this solves the You have requested a non-existent parameter[...] error, the actual value is now %%someText%%. I expected Symfony to return the unsecaped value instead, i.e., %someText%.

Sure I could str_replace('%%', '%', '%%someText%%'), but this feels hack-ish.

How would I change the value to actually get %someText% instead?

Here's where the configuration is loaded:

// Namespace and use statements omitted for brevity
class MyBundleNameExtension extends ConfigurableExtension
{
    /**
     * @inheritDoc
     */
    protected function loadInternal(array $mergedConfig, ContainerBuilder $container)
    {
        $loader = new Loader\YamlFileLoader($container, new FileLocator(__DIR__ . '/../Resources/config'));
        $loader->load('config.yml');

        p_r($mergedConfig["my_configuration"]); // Prints %%someText%%
    }
}

I've verified that using both ' and " yields the same result.

I wanted to know if it was possible to put twig code in ckeditor and that it interprets correctly the code in order to generate the HTML code.

I've already seen some configurations (using "protectedSource") that allow to put twig code within ckeditor but when I do that, the twig code is still interpreted as a string.

My goal here is to create some twig functions that I could use inside CKEditor.

Example :

Let's say that the "my_complex_table_function" function return a complex table, i would like to be able to put

 {{ my_complex_table_function }}

in CKEditor and that it returns the table in the front page.

Is that possible ?

Thanks guys

I need to functionally test the a subscriber in Symfony 4 and I'm having problems finding how. The Subscriber has the following structure

/**
* Class ItemSubscriber
*/
class ItemSubscriber implements EventSubscriberInterface
{
    /**
     * @var CommandBus
     */
    protected $commandBus;

    /**
     * Subscriber constructor.
     *
     * @param CommandBus $commandBus
     */
    public function __construct(CommandBus $commandBus)
    {
        $this->commandBus = $commandBus;
    }

    /**
     * {@inheritdoc}
     */
    public static function getSubscribedEvents()
    {
        return [
            CommandFailedEvent::NAME => 'onCommandFailedEvent',
        ];
    }

    /**
     * @param CommandFailedEvent $event
     *
     * @throws Exception
     */
    public function onCommandFailedEvent(CommandFailedEvent $event)
    {
        $item = $event->getItem();
        $this->processFailed($item);
    }

    /**
     * Sends message 
     *
     * @param array $item
     *
     * @throws Exception
     */
    private function processFailed(array $item)
    {
        $this->commandBus->handle(new UpdateCommand($item));
    }
}

The flow of the subscriber is receiving an internal event and send a message by rabbit through the command bus to another project.

How can I test that dispatching the event CommandFailedEvent the line in processFailed(array $item) is executed?

Does anyone has documentation on best practices to test Events and Subscribers in Symfony 4?

I have a little problem with my Symfony 4 login page. When users submits the form, the following error appears:

Notice: A non well formed numeric value encountered

and yet when I go to the data base the login is there, the password is there too (hash it out of course) and despite this it doesn't work.

and sometimes it starts working but only when env=dev but when env=prod there is an error 500

this is the controller

What I want

When I submit my form, my DB technician column should take the ID of the technician chosen.

What i get

But I come to this error: Expected argument of type "string", "App \ Entity \ Users" given. My column is declared in string and I send an id or 2 digits so I don't understand.

Thank you very much for your answers or help

I have the entity Page identified by slug. Also I have the action to view a page in the Page controler :

class PageController extends AbstractController
{
   /**
    * @Route("/{slug}", name="fronend_page")
    */
   public function show(Page $page)
   {
       return $this->render("font_end/page/show.html.twig", [
           "page" => $page,
       ]);
   }
}

I am looking for good practice to validate the slug ( check if exist in routes) before save it in the database without use prefixes Example :

route exist : @route ("/blog")

check if blog exist before create slug : /{slug} = /blog

I have created a solution but I am not sure it is the best solution: I Create a custom Validation Constraint

class ContainsCheckSlugValidator extends ConstraintValidator
{

   private $router;

   public function __construct(UrlGeneratorInterface $router)
   {
       $this->router = $router;
   }

   public function validate($value, Constraint $constraint)
   {
       if (!$constraint instanceof ContainsCheckSlug) {
           throw new UnexpectedTypeException($constraint, ContainsCheckSlug::class);
       }

       // custom constraints should ignore null and empty values to allow
       // other constraints (NotBlank, NotNull, etc.) take care of that
       if (null === $value || '' === $value) {
           return;
       }
       $drp = true;
       try {
           $url = $this->router->generate('fronend_page', [
               'slug' => $value,
           ]);
       } catch (RouteNotFoundException $e) {
           $drp = false;
       }
       if ($drp) {
           $this->context->buildViolation($constraint->message)
               ->setParameter('{{ string }}', $value)
               ->addViolation();
       }


   }
}

thanks

I have a little problem with my Symfony 4 login page. When users submits the form, the following error appears:

Notice: A non well formed numeric value encountered

and yet when I go to the data base the login is there, the password is there too (hash it out of course) and despite this it doesn't work.

this is the controller

<?php

namespace App\Controller ;

use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;

//Class pour authentification
use Symfony\Component\Security\Http\Authentication\AuthenticationUtils ;


class SecurityController extends AbstractController
{

  /**
  * @Route("/login" , name="login")
  */
  public function login(AuthenticationUtils $authentication)
  {
    $error = $authentication->getLastAuthenticationError();

    $lastUsername = $authentication->getLastUsername();

    return $this->render('Authentification/login.html.twig' ,[
      'error'         => $error,
      'last_username' => $lastUsername,
      ]) ;
  }
}

I have an authentication issue on a production server, the issue is very likely to be non-code related but rather an IT configuration issue...

To prove this I would like to check if API Platform receives the Authorization header when trying to fetch data. I have not found anything about logs in the API Platform documentation. What is the right way of logging API requests and their headers using the Symfony logging systems, knowing that I don't have access to the actual controller code as it is purely configured using the APIRessource annotation on entities ?

To be clear, everything works fine in local, I'm not looking for a solution to my problem here, just a clean way to change the log format or add logs to incoming request using API Platform.

I'm trying to figure it out how configure symfony + memcached adapter to use persistent connections.

In memcached documentation I found that it has a constructor argument

Memcached::__construct ([ string $persistent_id ] )

https://www.php.net/manual/en/memcached.construct.php

But by default in Symfony code I see it is set to null.

namespace Symfony\Component\Cache\Traits;

trait MemcachedTrait
{
    private static $defaultClientOptions = [
        'persistent_id' => null,
        'username' => null,
        'password' => null,
        \Memcached::OPT_SERIALIZER => \Memcached::SERIALIZER_PHP,
    ];

I've try to set it trough the default_memcached_provider config like this:

default_memcached_provider: memcached://localhost?tcp_keepalive=true&persistent_id=booking_website

Is it ok? How can I tell if it's working.

I'm monitoring the server with newrelic but I don't see any change time spent in memcached, perhaps because I don't have much traffic.
