Question

我试图覆盖mongoose模型的setter，因为我想创建自己的Date对象，但检查documentation我做了以下但是仍未调用setter：

var mongoose = require('mongoose');

function strToDate(dateStr){
    var dateStr = dateStr.split('/');
    console.log('parsed a date!');
    return new Date(dateStr[0],dateStr[1],dateStr[2],dateStr[3],dateStr[4], dataStr[5]);
}

var infoSchema = new mongoose.Schema({
    code: {type : String, require: true},
    valve: {type : Number, require: true},
    dataTime: {type: Date, require: true, set: strToDate}, 
    status: {type: Boolean, require: true, default: false },
    elapsedTime: 0
});


var dataLogSchema = new mongoose.Schema({
    boardId: {type: String, require: true, unique: true},
    logInfo:[infoSchema]
});



module.exports = mongoose.model('DataLog', dataLogSchema);

有什么不对？我使用的是mongoose 4.0.5

Answer 1

我用mongoose 4.0.6尝试了这个例子

var mongoose = require('mongoose');
var Schema = mongoose.Schema;

var InfoSchema = new Schema({
  dataTime: {type: Date, require: true, set: strToDate}
});

function strToDate(stringDate) {
  var sDate = stringDate.split('/');
  return new Date(sDate[0], sDate[1], sDate[2], sDate[3], sDate[4], sDate[5]);
}

var Info = mongoose.model('Info', InfoSchema);

var info = new Info();
info.dataTime = '1995/11/17/3/24/0';
console.log(info.dataTime);  //Sun Dec 17 1995 03:24:00 GMT-0400 (BOT)

问题是你的strToDate函数中有一个拼写错误导致函数抛出ReferenceError异常（Mongoose显然只是吃掉它）。 dataStr[5]应该是dateStr[5]。

所以只需将该函数的最后一行更改为：

return new Date(dateStr[0],dateStr[1],dateStr[2],dateStr[3],dateStr[4],dateStr[5]);

mongoose schema setter overwrite函数不被称为
