vapor - Automatic model migrations in Vapor 4/Fluent still exist?

Question

I'm trying to follow the upgrade guide to Vapor 4 with my Vapor 3 project. I have used the Vapor 3 automatic model migrations a lot. But going through the Vapor 4 upgrade guide, they aren't mentioned anymore, in fact they use specific migrations for every model. So, don't they exist anymore?

据我所知，有两种选择（感谢@vzsg）

• 您可以将--auto-migrate参数传递给进程（在命令行中快速运行 Run serve --auto-migrate，并通过 Xcode 中的 Edit Scheme）
• 您可以手动调用并等待迁移try app.autoMigrate().wait()
