Jsonb type limited convert

[halfik]

JsonB type has now limitation on convertToPhpValue function. You can't convert to some custom php classes now like this:

public function convertToPHPValue($value, AbstractPlatform $platform): Currency

Any reason behind limiting convert to only simple php types?

I don't fully understand your idea. Can you please elaborate with more details?

You limited types int this when it convertio into. It can convert any object itno jsonb, but you won't be able to recreate same object from jsob.

So u can conber instance of my CustomClass but i can't get it back since im limited to simple types only.

Can you add some code samples, please? The phpdoc for Jsonb clearly says that only array|bool|float|int|string|null data types are supported.

Yes and that is an issue. You can conver instance of CustomClass into jsonb on db, but u cant conver from db to CustomClass bc you can get only array|bool|float|int|string|null

convertToDatabaseValue allows to convert any object u want into db string convertToPHPValue won't allow to recreate it

And its a big issue in DDD aproach where u have lot of domain defined custom objects you want to store as jsonb.
