我正在尝试创建一个具有各种时间戳（createdat、updatedat、deletedat）和默认值的模型。如何做到这一点？我试着玩弄那辆车 prepare 方法，但无济于事。先谢谢你。这是我现在的课：
prepare

蒸汽提供了类似于：
static func prepare(on connection: MySQLConnection) -> Future<Void> { return Database.create(self, on: connection) { builder in builder.field(for: \.iq, type: .int, .default(.literal("123456"))) ...
这应该与日期以及工作。或者您可以尝试在自定义初始化中设置它们：
required init(id:Int?, adressLine1:String, adressLine2:String?, city:String, state:String, zip:String) { self.id = id self.adressLine1 = adressLine1 self.adressLine2 = adressLine2 self.city:String = city:String self.state = state self.zip = zip self.createdAt = Date() //<---- here self.updatedAt = Date() //<---- here self.deletedAt = Date() //<---- here }
或：
required init(id:Int?, adressLine1:String, adressLine2:String?, city:String, state:String, zip:String, createdAt:Date = Date()/*<--- here*/, updatedAt:Date = Date()/*<--- here*/,deletedAt:Date = Date()/*<--- here*/) { self.id = id self.adressLine1 = adressLine1 self.adressLine2 = adressLine2 self.city:String = city:String self.state = state self.zip = zip self.createdAt = createdAt self.updatedAt = updatedAt self.deletedAt = deletedAt }
