【中文标题】SailsJS 1.0:Mongo 中模型的 .create() 错误,单向关联到存储在 MySQL 中的模型【英文标题】:SailsJS 1.0 : Error in .create() for a model in Mongo with One Way Association to a model stored in MySQL 【发布时间】:2019-01-13 05:16:58 【问题描述】:

我有一个 Users 模型存储在 MongoDb 和一个 UserTypes 模型存储在 MySQL

当我尝试创建新用户时:

Users.create(name: "Shivam", userType: 1)

我收到以下错误:

 AdapterError: Unexpected error from database adapter: Invalid replacement foreign key value provided for association (`userType`).  Cannot interpret `1` as a Mongo id.


(Usually, this is the result of a bug in application logic.)

 code: 'E_CANNOT_INTERPRET_AS_OBJECTID'  

但是,.populate() 工作正常:

Users.findOne('USER_ID_HERE').populate('userType')

产生以下结果:


  id: "USER_ID_HERE",
  name: "Shivam",
  userType: 
    id: 1,
    label: "Student"
  

这是我的模型:

Users.js

module.exports = 

  datastore: 'mongoDb',
  attributes: 
   id: type: 'string', columnName: '_id', required: false,

    name: 
      type: 'string',
      required: false,
      allowNull: true,
      maxLength: 50,
      minLength: 3
    ,

    userType: model: 'usertypes', required: true,
  
;

UserTypes.js

module.exports = 

  datastore: 'default',
  attributes: 

    id: type: 'number', autoIncrement: true,

    label: 
      type: 'string',
      maxLength: 255,
      required: true,
      unique: true
    ,
    createdAt: false,
    updatedAt: false,
    users: collection: 'users', via: 'userType'

  

;

其中default 数据存储为mysqlmongoDb 数据存储为MongoDb

这是版本信息:

Version Info:

     : node           : v8.1.2

我做错了什么?

【问题讨论】:

我还报告了一个Bug:github.com/balderdashy/sails/issues/4484 【参考方案1】:

对于遇到相同问题的其他人,这里有一个修补程序:

使用 MySQL 适配器为所有模型设置 dontUseObjectIds: true

这似乎欺骗了 sails-mongo 适配器,使其不使用 sails-mysql 适配器检查模型外键的 ObjectId。

请注意,这不是一个正确的解决方案,而只是一种解决方法。
