node.js - Mongoose Actor 错误: Cast to ObjectId failed for value at path "_id"

Question

这是我的架构:

let mongoose = require('mongoose');
let schema = new mongoose.Schema({
  type: String,
  value: String,
  attributes:[mongoose.Schema.Types.Mixed],
  created_at: Date,
  updated_at: Date
})

然后我用 {type:'user_id', value: 1} 创建一个新集合，然后我通过查询获取新数据:

{type: 'user_id', value: '1'}

没问题，结果如下:

"_id" : ObjectId("5874c5dbed927207df177d3b"),
"type" : "phone",
"value" : "13811785500",
"updated_at" : ISODate("2017-01-10T11:30:19.266Z"),
"created_at" : ISODate("2017-01-10T11:30:19.266Z"),
"attributes" : [], 

然后，我使用集合的 ObjectId 查询保存的集合:

models.findBydId("5874c5dbed927207df177d3b")

它抛出错误:

CastError: Cast to ObjectId failed for value "5875976f8a03b2229c544c50"    at path "_id" for model "vertex"

谁能告诉我出了什么问题吗？谢谢。

你应该尝试这个->

models.find({"_id": ObjectId("5874c5dbed927207df177d3b")});
