Question

我在mongoose中有这个“架构”，在我的字典中有一个数组并有其他嵌入式数组，

如果没有嵌入对象，我可以保存，如何保存嵌入对象？

var ReportSchema   = new Schema({
    appVersion: { type: String, required: true},
    osVersion: { type: String, required: true},
    deviceType: { type: String, required: true},
    userID: { type: String, required: true},
    sessionIDtimestamp: { type: String, required: true},

    eventItem : [new Schema ({
        eventType:{type :String},
        startTime:{type :String},
        endTime:{type :String},
        params:[new Schema ({
            val:{type :String}
        })]
    })]
});

在我的路由器上：

apiRouter.route('/report') 
    .post(function(req, res) {
        var report = new Report();       

        report.appVersion = req.body.appVersion;   
        report.osVersion = req.body.osVersion;   
        report.deviceType = req.body.deviceType;    
        report.userID = req.body.userID;   
        report.sessionIDtimestamp = req.body.sessionIDtimestamp;   

        for (var i = req.body.events.length - 1; i >= 0; i--) {
            var requestStringa = util.inspect(req.body.events, {showHidden: false, depth: null});
            console.log("entro :"+requestStringa);      
        };

        report.save(function(err) {
            if (err) {
                return res.send(err);
            }
            res.json({ message: 'report created!' });
        });
    })

我也不认为枚举数组的方式很好吗？

编辑事件日志

entro :[ { eventType: 'Account_Rated_Pressed',
    startTime: '1435819399',
    endTime: '1435819399',
    params: [ { paramKey: 'rating', paramValue: '5' } ] },
  { eventType: 'RateableDetail',
    startTime: '1435819399',
    endTime: '1435819399',
    params: [ { paramKey: 'rating', paramValue: '5' } ] } ]

如何保存我的嵌入对象欢呼声

要保存嵌入文档，只需为数组字段eventItem分配请求对象值，如下所示：

apiRouter.route('/report') 
    .post(function(req, res) {
        var report = new Report();       

        report.appVersion = req.body.appVersion;   
        report.osVersion = req.body.osVersion;   
        report.deviceType = req.body.deviceType;    
        report.userID = req.body.userID;   
        report.sessionIDtimestamp = req.body.sessionIDtimestamp;   
        report.eventItem = req.body.events;

        report.save(function(err) {
            if (err) {
                return res.send(err);
            }
            res.json({ message: 'report created!' });
        });
    })

在req.body.event是对象而不是数组的情况下，您需要使用JavaScript push() 方法将对象推送到数组。比如说，如果req.body.event具有结构

{ 
    eventType: 'Account_Rated_Pressed',
    startTime: '1435819399',
    endTime: '1435819399',
    params: [ { paramKey: 'rating', paramValue: '5' } ] 
}

然后你可以做

apiRouter.route('/report') 
    .post(function(req, res) {
        var report = new Report();       

        report.appVersion = req.body.appVersion;   
        report.osVersion = req.body.osVersion;   
        report.deviceType = req.body.deviceType;    
        report.userID = req.body.userID;   
        report.sessionIDtimestamp = req.body.sessionIDtimestamp;   
        report.eventItem.push(req.body.event);

        report.save(function(err) {
            if (err) {
                return res.send(err);
            }
            res.json({ message: 'report created!' });
        });
    })

mongoose mongo.js使用数组保存数组到集合
