Symfony - controller.service_arguments

01_Problem.md

I'm like 6 hours old in working with symfony, and I really love the documentation, but this one bit I don't get what I'm doing wrong.

When calling my url: /game/complete?personId=1&exerciseId=2 i get the error:

Could not resolve argument $personId of "App\Controller\GameController::complete()", maybe you forgot to register the controller as a service or missed tagging it with the "controller.service_arguments"?

Problem Solved: I was missing the params in my routing annotation, see updated file.

GameController.php

<?php

declare(strict_types=1);

namespace App\Controller;

use App\Entity\Exercise;
use App\Entity\Person;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\Routing\Annotation\Route;

class GameController extends AbstractController
{
    /**
     * @Route("/game", name="game")
     */
    public function game()
    {
        return $this->render('game/index.html.twig', [
            'controller_name' => 'GameController',
            'exercise' => $this->pickRandomExercise()
        ]);
    }

    /**
     * @param int $personId
     * @param int $exerciseId
     *
     * @return \Symfony\Component\HttpFoundation\Response
     * @Route("/game/complete", name="game-complete", defaults={"personId": 1, "exerciseId": 1})
     */
    public function complete(int $personId, int $exerciseId)
    {
        /** @var Person $person */
        $person = $this->getDoctrine()->getRepository(Person::class)->find($personId);
        $exercise = $this->getDoctrine()->getRepository(Exercise::class)->find($exerciseId);
        $person->addCompletedExercise($exercise);
        return $this->redirectToRoute('game');
    }

services.yaml

# This file is the entry point to configure your own services.
# Files in the packages/ subdirectory configure your dependencies.

# Put parameters here that don't need to change on each machine where the app is deployed
# https://symfony.com/doc/current/best_practices/configuration.html#application-related-configuration
parameters:

services:
    # default configuration for services in *this* file
    _defaults:
        autowire: true      # Automatically injects dependencies in your services.
        autoconfigure: true # Automatically registers your services as commands, event subscribers, etc.

    # makes classes in src/ available to be used as services
    # this creates a service per class whose id is the fully-qualified class name
    App\:
        resource: '../src/*'
        exclude: '../src/{DependencyInjection,Entity,Migrations,Tests,Kernel.php}'

    # controllers are imported separately to make sure services can be injected
    # as action arguments even if you don't extend any base controller class
    App\Controller\:
        resource: '../src/Controller'
        tags: ['controller.service_arguments']

    # add more service definitions when explicit configuration is needed
    # please note that last definitions always *replace* previous ones

App\Controller\:
    resource: '../src/Controller/'
    tags: ['controller.service_arguments']

When i add this code got another error

" Invalid service id: "App\Controller" in /Applications/XAMPP/xamppfiles/htdocs/saas/src/../config/services.yaml (which is being imported from "/Applications/XAMPP/xamppfiles/htdocs/saas/src/Kernel.php") "

It's really cool that you followed up on this, I totally forgot about it. Perhaps it will help someone else in the future.
