Sails.js 未定义不是函数-Sails中的错误

当我运行

Sails lift

时，我在Sails中遇到以下错误，如下所示

usr/local/lib/node_modules/sails/node_modules/waterline/lib/waterline/util /schema.js:59
attributes[key].type = attributes[key].type.toLowerCase();

我的模型具有以下属性

SerialNo: {
  type: 'integer',
  unique: true,
  required: true,
  index: true
},

CreatedAt: {
  type: Date,
  default: Date.now
}

我不明白这个错误。我在相应的控制器中没有任何功能。到目前为止，我还没有定义任何路线

有人能帮我解决这个错误吗？

在您的模型中，您必须这样更改您的模型：

SerialNo: {
  type: 'integer',
  unique: true,
  required: true,
  index: true
},

CreatedAt: {
  type: 'Date',
  default: Date.now
}

---

注意：在sails中，type必须有这个“”

您不必使用隐式存在的

createdAt

属性

Date

类型在水线中不存在，您必须使用

type:'datetime'

默认值

不存在。您可以使用
defaultsTo
@YannBertrand。我确实输入了“datetime”，它对我很有用。当我输入class='date'时，我仍然得到输出。你能告诉我这两者有什么不同吗。
