Symfony3, Doctrine2, custom fixtures loader - doctrine-orm

Question

I am trying to make a custom fixture that will take data from a csv file, parse it in a specific way, create the objects, insert the data and flush it to the database.
My problem is that my file lives in AppBundle/Command and I do not know how to access the manager in order to persist and flush my file.
So my question is: How do i access doctrine's manager?
<?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();
}
}
Here is the error that it outputs
[Symfony\Component\Debug\Exception\FatalThrowableError]
Fatal error: Call to undefined method AppBundle\Comm
and\LoadFixturesCommand::getDoctrine()

You haven't the helper method getDoctrine() in a command (instead this exists in a controller if inhered from Symfony\Bundle\FrameworkBundle\Controller\Controller).
try with
$this->getContainer()->get('doctrine')
instead of
$this->getDoctrine()
Hope this help
