為什么我可以從命令列查找/保存，但不能在我的Symfony應用程式中查找/保存？-有解無憂

對于我的個人開發，我嘗試使用此 repo https://github.com/dunglas/symfony-docker作為 Docker 基礎來創建 PHP 8/Symfony 5 環境。

我可以在 https://localhost 上啟動我的應用程式，更新我的專案會反映在瀏覽器上。但是我對Doctrine有一個奇怪的事情。實際上，我可以使用 Symfony 命令bin/console doctrine:schema:update --force、使用 Doctrine Migrations 或使用命令插入資料來更新我的資料庫模式。但是，當我嘗試在我的 Symfony 應用程式中查找/保存資料時，當我找到并且在創建/更新時沒有資料插入時沒有結果。

這是我的 docker-compose.yml （幾乎與 repo 相同，只有資料庫 > 卷更改）：

和我的 env 檔案（再次幾乎與原始檔案相同）：

# 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).

編輯：

這是我的瀏覽器應用請求測驗代碼：

<?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',
        ]);
    }
}

這是我的配置原則：

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

And here is a part of code that is called from command line and where it works:

uj5u.com熱心網友回復：

在持久化之后，您必須在 Doctrine 物體管理器上呼叫flush：

$this->entityManager->flush();

查看檔案。

uj5u.com熱心網友回復：

好的，我終于找到了解決方案。我更改了未直接反映在 Docker 構建中的 .env 檔案，因為我必須像這樣設定它：

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

或者替換組態檔中的資料庫默認名稱。

謝謝你的幫助：）
