以下是我的风帆模型，每当我尝试 save() 时都会收到以下错误

[Error: Unknown rule: address]

使用与猫鼬相似的模型，没有任何问题，有人能看到我的模型中的任何错误吗？

谢谢！

【解决方案1】：

您不能使用 Sails/Waterline ORM 嵌套这样的数据。问题在于meta : {} 位。就sails 而言，您定义了一个名为meta 的属性，并试图应用名为address, city, mobile, email 等的规则（例如type : 'string'），这些都不是有效规则。

我建议您创建一个名为address 或userMeta 或类似名称的新模型，然后将address, city, mobile, email 等放入其中。然后将它们关联起来，或者，完全摆脱 meta : {} 包装器并拥有它......

};

请参阅sails attributes，了解您可以或不能在模型描述中添加的内容
