为什么我可以从命令行 find/save 而不是在我的 Symfony 应用程序中？

Question

为了我的个人发展，我尝试使用这个 repo https://github.com/dunglas/symfony-docker 作为 Docker 基础来创建一个 PHP 8/Symfony 5 环境。

我可以在 https://localhost 上启动我的应用程序，更新我的项目会反映在浏览器上。但是我对 Doctrine 有一个奇怪的看法。实际上，我可以使用 Symfony 命令 bin/console doctrine:schema:update --force 更新我的数据库模式，使用 Doctrine Migrations 或也使用命令插入数据。但是，当我尝试在我的 Symfony 应用程序中 find/save 数据时，我发现没有结果并且 create/update.

上没有数据插入

这是我的 docker-compose.yml（几乎与 repo 相同，只有数据库 > 卷发生变化）：

还有我的 env 文件（同样几乎与原始文件相同）：

# In all environments, the following files are loaded if they exist,
# the latter taking precedence over the former:
#
#  * .env                contains default values for the environment variables needed by the app
#  * .env.local          uncommitted file with local overrides
#  * .env.$APP_ENV       committed environment-specific defaults
#  * .env.$APP_ENV.local uncommitted environment-specific overrides
#
# Real environment variables win over .env files.
#
# DO NOT DEFINE PRODUCTION SECRETS IN THIS FILE NOR IN ANY OTHER COMMITTED FILES.
#
# Run "composer dump-env prod" to compile .env files for production use (requires symfony/flex >=1.2).

编辑：

这是我的浏览器应用请求测试代码：

<?php

namespace App\Controller;

use App\Entity\Category;
use App\Entity\Product;
use App\Finder\ProductFinder;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;

#[Route('/front')]
class FrontProductController extends AbstractController
{
    #[Route('/product', name: 'front_product')]
    public function index(ProductFinder $finder, Request $request): Response
    {

        $category = new Category();
        $category->setName('enpme')
            ->setKey('pzafn');

        $this->getDoctrine()->getManager()->persist($category);
        $this->getDoctrine()->getManager()->flush();


        $this->getDoctrine()->getRepository(Product::class)->findAll();

        return $this->render('front_product/index.html.twig', [
            'controller_name' => 'FrontProductController',
        ]);
    }
}

这是我的配置原则：

doctrine:
    dbal:
        url: '%env(resolve:DATABASE_URL)%'

        # IMPORTANT: You MUST configure your server version,
        # either here or in the DATABASE_URL env var (see .env file)
        #server_version: '13'
    orm:
        auto_generate_proxy_classes: true
        naming_strategy: doctrine.orm.naming_strategy.underscore_number_aware
        auto_mapping: true
        mappings:
            App:
                is_bundle: false
                type: annotation
                dir: '%kernel.project_dir%/src/Entity'
                prefix: 'App\Entity'
                alias: App

这是从命令行调用的代码的一部分及其工作位置：

Answer 1

持久化后必须在 Doctrine 实体管理器上调用 flush：

$this->entityManager->flush();

看看documentation。

Answer 2

好的，我终于找到了解决方案。我更改了未直接反映在 Docker build 中的 .env 文件，因为我必须这样设置它：

POSTGRES_DB=my_db_name docker-compose up -d --build

或者替换配置文件中的数据库默认名称。

为什么我可以从命令行 find/save 而不是在我的 Symfony 应用程序中？

Why I can find/save from command line but not in my Symfony app?

php

doctrine

symfony

docker
