关于我的申请的一些背景:
问题:如果我运行命令migrations:diff从实体类中的更改生成迁移,则会出现以下异常:
[Doctrine\DBAL\DBALException] Unknown column type "json" requested.
Any Doctrine type that you use has to be registered with \Doctrine\DBAL\Types\Type::addType(). You can get a list of all the known types with \Doctrine\DBAL\Types\Type::getTypesMap().
