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
