Question

我想按照＆＃34; symfony＆＃34;的理念来减少控制器。也许我需要使用这些服务，或者有什么要标准的？

这是我的功能

namespace AppBundle\Controller;

use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use AppBundle\Entity\Users;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Method;
use Symfony\Component\HttpFoundation\Request;
...
/**
 * @Route("/save", name="save")
 * @Method({"GET"})
 * @return Response
 */
public function saveAction()
{
    //returns an array of users on this date
    //array(
    //    "Kate" => 18,
    //    "John" => 24,
    //    "Albert" => 31,
    //);
    $users= $this->get("users")->users();

    $em = $this->getDoctrine()->getManager();

    $checkNow = $this->getDoctrine()
            ->getRepository('AppBundle:User')
            ->findOneBy(array("date" => $this->nowDate));

    if(null === $checkNow) {
        foreach($users as $name => $qty) {
            $userDB = new User();
            $userDB->setDate($this->nowDate);
            $userDB->setQty($qty);
            $userDB->setName($name);
            $em->persist($userDB);
        }

        $em->flush();
    }

    return new Response("New users are added");
}

提前谢谢。

Symfony只是一个框架并允许任何内容，但通常与数据库相关的内容在EntityRepository中完成。我通常将EntityRepositories保留用于复杂查询或数据库操作。

您可以通过服务来保持控制器的精益，如下所示：

示例控制器操作：

$users= $this->get("users")->users();
$userService = $this->get('user.service');

if (!$userService->hasUsersCreatedOn($this->nowDate) {
    $userService->createMultiple($users);
}

return 'message';

示例用户服务：

public function createMultiple($users); // just loops through each and creates

public function create($name, $qty, $date) {
    $user = new User();
    $user->setDate($this->nowDate);
    $user->setQty($qty);
    $user->setName($name);

    $this->entityManager->persist($user);
    $this->entityManager->flush($user);

    return $user;
}

我在哪里可以放置代码＆＃34;保存到数据库＆＃34;，它位于控制器中
