Question

我正在尝试在我的数据库中创建许多相同的对象，以更准确地插入一些用户。首先，我尝试在每次循环后刷新实体管理器，但它不起作用。经过一些研究，我发现我可以批量进行，所以我尝试每15个循环刷一次，但是我仍然会在30秒后（大约180次查询）超时。对于小到200-250的数字，它们不应该快速，或几乎是即时的吗？我怎样才能让它没有超时并更快地插入它们？

我的功能是向randomuser.me发出请求并检索用户的json。我将该数据检索到一个数组中并使用它来填充我的用户信息。我还有一个$ fields数组，它有某些医学领域（不会在这里发布，因为它只是一个纯文本数组）。它还为用户条目添加了相关的设置条目（包含医生工作的字段和他的图片）。

 public function generateAction()
    {
        $em = $this->getDoctrine()->getManager();
        $generated = 0;

        $url = "https://randomuser.me/api/?results=250&nat=us";
        $str = file_get_contents($url);
        $medics = json_decode($str);


   $medicsgruop = $this->getDoctrine()->getRepository('MedAppBundle:Group')->findOneBy(array('name' => 'medics'));

    if (!$medicsgruop) {
        $medicsgruop = new Group('medics');
        $medicsgruop->addRole('ROLE_MEDIC');
        $em->persist($medicsgruop);
        $em->flush();
    }
        $batchSize = 15;
        foreach ($medics->results as $i => $medic) {

            if ($this->fields[$i]) {
                $field = $this->fields[$i];
            } else {
                $field = array_rand($this->fields);
            }

            $fname = $medic->user->name->first;
            $lname = $medic->user->name->last;

            $image = $medic->user->picture->large;
            $email = $medic->user->email;

            $user = new User();
            //user
            $user->setUsername($lname.$fname);
            $user->setFirstname($fname);
            $user->setLastname($lname);
            $user->setEmail($email);
            $user->setEnabled(true);
            $user->setPlainPassword($fname.$lname);
            //group



            $user->addGroup($medicsgruop);
            $em->persist($user);
            //MEDIC SETTINGS
            $medsett = new MedicSettings();
            $medsett->setField($field);
            $medsett->setProfile($image);
            $medsett->setMedic($user);
            $em->persist($medsett);


            if (($i % $batchSize) == 0) {
                $em->flush();
                $em->clear();
            }
        }
        $em->flush();
        $em->clear();
        return $this->render(
            '@MedApp/Admin/generatemedics.html.twig',
            array('generated' => $generated, 'medics' => 'asd')
        );
    }

使用批处理方法时，大约有40个用户被添加到我的数据库中，但在达到最大执行时间后会停止。我做错了什么？

使用malcolm的建议来使用symfony中的Client命令。但该命令仍然运行缓慢。每个用户约1秒钟。并且它们每批次一次插入DB 15中。

class GenMedicsCommand extends ContainerAwareCommand
{
    /**

    protected function configure()
    {
        $this
            ->setName('doctrine:generate:medics')
            ->setDescription('Generate medics group, users, group-users, medic settings')
            ->addArgument(
                'number',
                InputArgument::REQUIRED,
                'How many medics to generate?'
            );
    }

    /**
     * {@inheritdoc}
     */
    protected function execute(InputInterface $input, OutputInterface $output)
    {
        $number = $input->getArgument('number');
        $this->generate($number,$output);

    }


    protected $fields = array(
        'Abdominal Radiology Radiology-Diagnostic',
        'Addiction Psychiatry Psychiatry',
        'Adolescent Medicine Pediatrics'    
    );

    //generate random medics for the win
    public function generate($nr,   OutputInterface $output)
    {


        $em = $this->getContainer()->get('doctrine.orm.entity_manager');
        $doctrine = $this->getContainer()->get('doctrine');

        $generated = 0;

        $url = "https://randomuser.me/api/?results=".$nr."&nat=us";
        $str = file_get_contents($url);
        $medics = json_decode($str);

        $medicsgruop = $doctrine->getRepository('MedAppBundle:Group')->findOneBy(array('name' => 'medics'));

        if (!$medicsgruop) {
            $medicsgruop = new Group('medics');
            $medicsgruop->addRole('ROLE_MEDIC');
            $em->persist($medicsgruop);
            $em->flush();
        }

        $batchSize = 15;
        foreach ($medics->results as $i => $medic) {
         //   set_time_limit(2);


            $randkey = array_rand($this->fields);
            $field = $this->fields[$randkey];

            $fname = $medic->user->name->first;
            $lname = $medic->user->name->last;

            $image = $medic->user->picture->large;
            $email = $medic->user->email;

            $user = new User();
            //user
            $user->setUsername($lname.$fname);
            $user->setFirstname($fname);
            $user->setLastname($lname);
            $user->setEmail($email);
            $user->setEnabled(true);
            $user->setPlainPassword($fname.$lname);
            //group


            $user->addGroup($medicsgruop);

            $em->persist($user);
            //MEDIC SETTINGS
            $medsett = new MedicSettings();
            $medsett->setField($field);
            $medsett->setProfile($image);
            $medsett->setMedic($user);
            $em->persist($medsett);
            $output->write(array($i+1,'|',$fname,'|',$lname,'|',$field,'|',$email,'|',$image));
            $output->writeln('');
            if (($i % $batchSize) == 0) {
                $em->flush();
                //  $em->clear();
            }
        }
        $em->flush();
        $em->clear();


        $output->writeln('done');
    }

}

Symfony2中的Doctrine多次插入超时
