Hello dwgebler,
I search a system to import a existing database for a while so thanks for your job.
But i'm a beginner and i don't know where i have to put this .php file ?
Somebody can help me please ?

Thanks.
Sorry for my english, i'm french.

Thanks man, very cool tool!

Specific tables entity generation (not all tables, only specified):

// fetch metadata
$driver = new \Doctrine\ORM\Mapping\Driver\DatabaseDriver(
    $em->getConnection()->getSchemaManager()
);

$specificTables = [
    $em->getConnection()->getSchemaManager()->listTableDetails('table_one'),
    $em->getConnection()->getSchemaManager()->listTableDetails('table_two')
];

$driver->setTables($specificTables, []);

$em->getConfiguration()->setMetadataDriverImpl($driver);

Thanks, this help a lot, and really really thanks to @MP92 you actually save my day.

Fatal error: Uncaught Doctrine\ORM\Mapping\MappingException: Table _article_recipe has no primary key. Doctrine does not support reverse engineering from tables that don't have a primary key. in E:_test\doctrine\vendor\doctrine\orm\lib\Doctrine\ORM\Mapping\Driver\DatabaseDriver.php:288

awesome,
you save the day
👍

Thanks. 👍

Thank you

Thank you!

I implement it to Symfony command and Doctrine Composer package here: https://github.com/baraja-core/doctrine/blob/master/src/Orm/DatabaseToDoctrineEntityExtractorCommand.php

@janbarasek Thank you for your improvements

@janbarasek Thanks for sharing.It's awesome for my project.

Its interesting that code generation got deprecated and to be removed in version 3.
Via EntityGenerator as in example above or through cli.
I wonder how would one get started with preexisting databases then (after v3 is stable)? probably just writing from scratch which seems pita.

see notes here: https://github.com/doctrine/orm/blob/3.0.x/UPGRADE.md

Deprecated code generators and related console commands
These console commands have been deprecated:
orm:convert-mapping
orm:generate:entities
orm:generate-repositories
These classes have been deprecated:
Doctrine\ORM\Tools\EntityGenerator
Doctrine\ORM\Tools\EntityRepositoryGenerator
Whole Doctrine\ORM\Tools\Export namespace with all its members have been deprecated as well.
