Question

我正在尝试创建一个自定义fixture，它将从csv文件中获取数据，以特定方式解析它，创建对象，插入数据并将其刷新到数据库。

我的问题是我的文件位于 AppBundle / Command ，我不知道如何访问管理器以便保持并刷新我的档案。

所以我的问题是：我如何访问doctrine的经理？

<?php

namespace AppBundle\Command;

use Symfony\Bundle\FrameworkBundle\Command\ContainerAwareCommand;
use Symfony\Component\Console\Input\InputArgument;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Output\OutputInterface;
use Doctrine\Common\Persistence\ObjectManager;
use AppBundle\Entity\Country;

class LoadFixturesCommand extends ContainerAwareCommand
{
    protected function configure()
    {
        $this->setName('app:load-fixtures'));
    }
    protected function execute(InputInterface $input, OutputInterface $output)
    {

        // file path
         $csvfile = '/home/amarui/Documents/studyin/country.csv';
        // if opened
        if (($handle = fopen($csvfile, 'r')) !== false) {

            // read line and breakes at semicolon(;)
            while (($line = fgetcsv($handle, 1000, ';', '"')) !== false) {

                $counter = 0;
                $i = 0; // counter for the array elements
                $city{$counter} = new Country();

                // read elements from breakpoint(;)
                foreach ($line as $value) {
                    // if the element has a comma(,)
                    if (strstr($line[$i], ',')) {
                        // breaks at comma(,)
                        $line[$i] = explode(',', $line[$i]);
                        // reads elements from the breakpoint(,)
                        foreach ($line[$i] as $multiple) {
                        // echo '<br /> count'.$i.' '.$multiple;
                        // TODO: 
                        }
                    } else {
                        // echo '<br /> count'.$i.' '.$value;
                        if ($i = 0) {
                            $city{$counter}->setName($value);
                        }
                    }
                    $i += 1; // next element in the array
                    $counter += 1; // updates the variable name
                    $this->getDoctrine()->getManager()->persist($city{$counter});
                }
            }
        }
        $this->getDoctrine()->getManager()->flush();
    }
}

这是输出的错误

[Symfony\Component\Debug\Exception\FatalThrowableError]  
  Fatal error: Call to undefined method AppBundle\Comm     
  and\LoadFixturesCommand::getDoctrine()

Answer 1

命令中没有辅助方法getDoctrine()（如果从Symfony\Bundle\FrameworkBundle\Controller\Controller加入，则存在于控制器中。）

尝试

$this->getContainer()->get('doctrine')

而不是

$this->getDoctrine()

希望这个帮助
