I ended up creating a custom command to migrate all the translations. I created a fake translation called "kr" and then updated all the record with "kr" to "fr" with an SQL query.
I used reflection and other "black magic" to get the properties with the Translatable
annotation, maybe this could help someone with the same problem. Here is the code:
class NormalizeTranslationsCommand extends ContainerAwareCommand
{
protected function configure()
{
$this
// the name of the command (the part after "app/console")
->setName('app:normalize-translations')
// the short description shown while running "php app/console list"
->setDescription('Normalizes the translations.')
// the full command description shown when running the command with
// the "--help" option
->setHelp('This command allows you to normalize the translations...')
;
}
protected function execute(InputInterface $input, OutputInterface $output)
{
// all the translatable classes
$classes = [
Entities\MyClass1::class,
Entities\MyClass2::class,
];
foreach ($classes as $class) {
$this->processClass($class, $output);
}
}
private function processClass($class, $output)
{
$output->writeln(sprintf('Processing class <info>%s</info>', $class));
// gets all the properties
$properties = $this->getProperties($class);
// gets the translatable properties
$translatableProperties = $this->getTranslatableProperties($properties, $class);
$output->writeln(sprintf('Found %d translatable properties: %s', count($translatableProperties), implode(', ', $translatableProperties)));
$defaultLanguage = 'kr'; // fake language
$em = $this->getContainer()->get('doctrine')->getManager();
$repository = $em->getRepository('Gedmo\\Translatable\\Entity\\Translation');
$items = $em->getRepository($class)->findAll();
$propertyAccessor = PropertyAccess::createPropertyAccessor();
foreach ($items as $item) {
foreach ($translatableProperties as $translatableProperty) {
$value = $propertyAccessor->getValue($item, $translatableProperty);
$repository->translate($item, $translatableProperty, $defaultLanguage, $value);
}
$em->flush();
}
}
private function getProperties($class)
{
$phpDocExtractor = new PhpDocExtractor();
$reflectionExtractor = new ReflectionExtractor();
// array of PropertyListExtractorInterface
$listExtractors = array($reflectionExtractor);
// array of PropertyTypeExtractorInterface
$typeExtractors = array($phpDocExtractor, $reflectionExtractor);
// array of PropertyDescriptionExtractorInterface
$descriptionExtractors = array($phpDocExtractor);
// array of PropertyAccessExtractorInterface
$accessExtractors = array($reflectionExtractor);
$propertyInfo = new PropertyInfoExtractor(
$listExtractors,
$typeExtractors,
$descriptionExtractors,
$accessExtractors
);
return $propertyInfo->getProperties($class);
}
private function getTranslatableProperties($properties, $class)
{
$translatableProperties = [];
// https://gist.github.com/Swop/5990316
$annotationReader = new AnnotationReader();
foreach ($properties as $property) {
try {
$reflectionProperty = new \ReflectionProperty($class, $property);
$propertyAnnotations = $annotationReader->getPropertyAnnotations($reflectionProperty);
foreach ($propertyAnnotations as $propertyAnnotation) {
if ($propertyAnnotation instanceof Translatable) {
// this property is translatable
$translatableProperties[] = $property;
}
}
} catch (\ReflectionException $e) {
// missing property
continue;
}
}
return $translatableProperties;
}
}
