在symfony4.2下,我有 translate entity(id,gb_name,fr_name)和 locationCountry entity(id,iso3166--2名称:GB,FR,DE…,Translate_id)
我定义了255个国家/地区(" GB","英国"," Angleterre"…)的CSV文件,我想将其推入带有DataFixture的翻译和位置越野实体表中。
我仔细阅读https://symfony.com/doc/current/bundles/doctrinefixturesbundle/index.html#sharing-objects-bets-bet--fixtures
和
PHP创建具有自动关系的固定装置
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);
}
$manager->flush();
我不确定 addReference 应该在 flush()?
之前src/datafixtures/locationcountryfixtures.php:
if ($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);
}
$manager->flush();
}
public function getDependencies() {
return array(
Translate::class,
);
}
如果我删除 addReference 翻译实体已充分填充。
但是使用上面的代码,它返回错误:
In SymfonyFixturesLoader.php line 76:
The "AppEntityTranslate" fixture class is trying to be loaded, but is not available. Make sure this class is defined as a service and tagged with "doctrine.fixture.orm".
我认为有正确的用途:
use DoctrineBundleFixturesBundleFixture;
use DoctrineCommonPersistenceObjectManager;
use DoctrineCommonDataFixturesDependentFixtureInterface;
use AppEntityLocationCountry;
use AppEntityTranslate;
感谢您的帮助
学说按字母顺序加载灯具文件;这就是为什么您会遇到错误的原因。您可以考虑在固定装置中使用函数getOrder
以设置首先加载的功能。
编辑:
您会遇到错误,因为您在getDependencies
方法中没有提供正确的类:
public function getDependencies() {
return array(
TranslateFixtures::class,
);
}
在这种情况下,我只需删除src/datafixtures/translatefixtures.php
和更改src/datafixtures/locationcountryfixtures.php做所有工作:
if ($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();
