Question

我试图这样做：

var hStatus = require（'models / hStatus'）;

var log = new hLog();

    hStatus.find({_id: /^value_/}, function(err, data){
            if(!err){
                    log.h = data;
                    log.save(function(err){
                         if(err){
                            console.log(err);
                         }else{
                            console.log('ok!');
                         }
                    });
            }
    });

数据var结构：

[ { outs: 
     [ [Object],
       [Object],
       [Object],
       [Object],
       [Object],
       [Object],
       [Object],
       [Object],
       [Object],
       [Object],
       [Object],
       [Object],
       [Object],
       [Object],
       [Object],
       [Object] ],
    c: 1457739456474,
    b: false,
    c: true,
    d: false },

我的模特是：

var hLog = new mongoose.Schema({
        a: Date,
        b: Number,
        c: String,
        d: String,
        e: Boolean,
        f: Boolean,
        g: String,
        h: [hStatus]
});

//this two same file
var hOuts = new mongoose.Schema({
        a: Number,
        b: String,
        c: Boolean,
        d: Boolean
});

var hStatus = new mongoose.Schema({
        a: String,
        b: Boolean,
        Outs: [hOuts],
        c: Number,
        d: Boolean   
});

但是保存功能返回：

ValidationError：CastError：Cast to Array因“{Outs：

的值而失败

这是正确的方法吗？

我不确定我错过了什么。

Answer 1

尝试 .push（）方法：

var log = new hLog();

    hStatus.findOne({_id: /^value_/}, function(err, data){
            if(!err){
                    log.h.push(data);
                    log.save(function(err){
                         if(err){
                            console.log(err);
                         }else{
                            console.log('ok!');
                         }
                    });
            }
    });

Answer 2

尝试以下

 let alertAction = UIAlertAction(title: "Ok", style: .Default) { (action) -> Void in
        self.navigationController?.pushViewController(vc as HomeViewController, animated: true)

    }

在你的json数据中

c: Number,
d: Boolean

类型不匹配
