问题描述

我尝试在控制器中使用函数 TechParentInsert 我收到错误:

I try to use the functions TechParentInsert in the controller I am getting an error:

尝试从命名空间TestyBundleController"调用函数TechParentInsert".

Attempted to call function "TechParentInsert" from namespace "TestyBundleController".

500 内部服务器错误 - UndefinedFunctionException

500 Internal Server Error - UndefinedFunctionException

在控制器中我有:使用 TestyBundleRepositoryTechParentRepository；"当我定义了TechParentInsert"

In controller I have: "use TestyBundleRepositoryTechParentRepository;" when i've defined "TechParentInsert"

推荐答案

自从 Symfony 2.8 和 Symfony 3.3(2017 年 5 月)自动装配以来，将依赖项传递给控制器的方式更加简洁.

Since autowiring in Symfony 2.8 and moreover Symfony 3.3 (May 2017) there is much cleaner way to pass dependencies to controller.

namespace TestyBundleController;

use SymfonyBundleFrameworkBundleControllerController;

use TestyBundleRepositorySortRepository;
use TestyBundleRepositoryTechParentRepository;

final class TestyController extends Controller
{
    /**
     * @var SortRepository
     */
    private $sortRepository;

    /**
     * @var TechParentRepository
     */
    private $techParentRepository;

    public function __constructor(
        SortRepository $sortRepository,
        TechParentRepository $techParentRepository,
    ) {
        $this->sortRepository = $sortRepository;
        $this->techParentRepository = $techParentRepository;
    }

    public function TechParentNewAction(int $parent = 0)
    {
        $sortNew = $this->sortRepository->findOneBy([
            'zz' => 0
        ]);

        $sortNew->setParentString($sortNew->getParentString() . (string) $sortNew->getId());
        $sortNew->setZz(1);

        $newRecordID = $sortNew->getId();

        $this->techParentRepository->TechParentInsert($newRecordID);

        // redirect etc...
    }
}

2.控制器服务注册

# app/config/services.yml
services:
    _defaults:
        autowire: true

    # PSR-4 autodiscovery
    TestyBundle:
        resource: '../../src/TestyBundle' # located in /src/TestyBundle

你准备好了！

您可以在以下 2 篇文章中阅读有关 Symfony 3.3 依赖注入(在这种情况下在配置中注册服务并在控制器中使用它)的新闻:

You can read about Symfony 3.3 dependency injection (in this case registering services in config and using it in controller) news in these 2 posts:
