symfony4 How create DataFixtures with entities relations - doctrine-orm

Question

Under Symfony4.2, I have a Translate entity (id, gb_name, fr_name) and LocationCountry entity (id, ISO3166-2 name: GB,FR, DE…, translate_id)
I define a CSV file with 255 countries ("GB", "Great Britain", "Angleterre"…) and I want to push it in Translate and LocationCountry entities tables with DataFixture.
I read carefully https://symfony.com/doc/current/bundles/DoctrineFixturesBundle/index.html#sharing-objects-between-fixtures
and
php create fixtures with automatic relations
src/DataFixtures/TranslateFixtures.php:
if ($csv_handle) {
while ($item = fgetcsv($csv_handle, $csv_max_line_length, $csv_delimiter, $csv_enclosure)) {
$obj = new Translate();
$obj->setGbValue($item[1]);
$obj->setFrValue($item[2]);
$this->addReference('country'.$item[0], $obj);
$manager->persist($obj);
}
fclose($csv_handle);
}
$manager->flush();
I am not sure addReference should be before flush() ?
src/DataFixtures/LocationCountryFixtures.php:
if ($csv_handle) {
while ($item = fgetcsv($csv_handle, $csv_max_line_length, $csv_delimiter, $csv_enclosure)) {
$translate_country = $this->getReference('country'.$item[0]);
$obj = new LocationCountry();
$obj->setIso3166Name($item[0]);
$obj->setTranslate($translate_country);
$manager->persist($obj);
}
fclose($csv_handle);
}
$manager->flush();
}
public function getDependencies() {
return array(
Translate::class,
);
}
If I remove addReference Translate entity is well filled.
But with the code above, it returns error:
In SymfonyFixturesLoader.php line 76:
The "App\Entity\Translate" fixture class is trying to be loaded, but is not available. Make sure this class is defined as a service and tagged with "doctrine.fixture.orm".
I think to have the right Use:
use Doctrine\Bundle\FixturesBundle\Fixture;
use Doctrine\Common\Persistence\ObjectManager;
use Doctrine\Common\DataFixtures\DependentFixtureInterface;
use App\Entity\LocationCountry;
use App\Entity\Translate;
Thank for your help

Answer 1

Doctrine loads the fixture files in alphabetical order; that's why you get an error. You can consider using function getOrder in your fixtures in order to set which one will be load first.
EDIT :
You get an error because you don't provide the right class in your getDependencies method :
public function getDependencies() {
return array(
TranslateFixtures::class,
);
}

Answer 2

In this case, I just remove src/DataFixtures/TranslateFixtures.php
and change src/DataFixtures/LocationCountryFixtures.php to do all job:
if ($csv_handle) {
while ($item = fgetcsv($csv_handle, $csv_max_line_length, $csv_delimiter, $csv_enclosure)) {
//$translate_country = $this->getReference('country'.$item[0]);
$country = new LocationCountry();
$translate_country = new Translate();
$translate_country->setGbValue($item[1]);
$translate_country->setFrValue($item[2]);
$country->setIso3166Name($item[0]);
$country->setTranslateCountry($translate_country);
$manager->persist($translate_country);
$manager->persist($country);
}
fclose($csv_handle);
}
$manager->flush();
