感谢您的帮助和宝贵的时间。如您所建议，我已经创建了如下的架构。现在，我想获取基于客户名称的记录，以计算他们在每个类别上花费的时间。请帮我解决这个问题。提前致谢。
/ * var query = {'timesheets [0] .categories [0] .catname'：“ Admin”} //我想获取所有类别为admin的记录或文档* /
Timesheet = new Schema({
created: {type: Date, default: Date.now},
categories: [{
catname: String,
custname: String,
hours: Number
}]
});
User = new Schema({
name: { type: String, required: true },
email:String,
password:String,
type:String,
timesheets: [Timesheet]
});
//timesheets: [{type: mongoose.Schema.Types.ObjectId, ref: 'Timesheet'}
var User = mongoose.model("User",User);
var Timesheet = mongoose.model("Timesheet",Timesheet);
module.exports = function(app) {
var timedata = {
created: new Date('2014-06-05'),
categories:[{catname:"Admin",cusname:"Sony",hours:8}]
}
var user = new User({
name:"Nelson",
email:"[email protected]",
password:"welcome123",
type:"Solutions"
});
var timesheet = new Timesheet(timedata);
user.timesheets.push(timesheet);
user.save(function(err,user){
console.log(user.timesheets.timesheet);
})
//console.log('category name');
//console.log(user.timesheets[0].categories[0].catname)
var query = {'timesheets[0].categories[0].catname':"Admin"}
// I want to get
all the records or documents with category admin
User.find(query,function(err,catname){
console.log('catname')
console.log(catname)
})
要创建子模式，您应该首先定义它，然后将其插入主模式。另外，如果您预计会有很多时间表，则最好参考一个独立的架构。在这两种情况下，将它们附加到用户架构都是有意义的：
var Timesheet = new Schema({
created: {type: Date, default: Date.now},
categories: [{
name: String,
custname: String,
hours: Number
}]
});
使用嵌入式文档：
var User = new Schema({
timesheets: [Timesheet]
});
然后可以使用以下命令直接进行插入：
// create new timesheet doc using your user doc
var timesheet = user.timesheets.create(myData);
user.timesheets.push(timesheet);
或简单地：
user.timesheets.push(data);
使用参考文件：
var User = new Schema({
timesheets: [{type: Schema.Types.ObjectID, ref: 'Timesheet'}]
});
插入：
// push timesheet reference to your user doc
var timesheet = new Timesheet(data);
user.timesheets.push(timesheet._id);
