Question

我是MongoDb的新手，我对插入数据有疑问。我用于用户＆＃39;的Mongoose架构系列：

public interface UILInterfaceNative extends Library{
    public PointerByReference Initialize(int hba, int port);
    public int Scan(PointerByReference uil);
}

public class Main {

    /**
     * @param args the command line arguments
     */        
    public static void main(String[] args) {
        // TODO code application logic here
        UILInterfaceNative uil = (UILInterfaceNative)Native.loadLibrary("UILInterfaceNative", UILInterfaceNative.class);
        PointerByReference uilPointer = new PointerByReference();
        uilPointer = uil.Initialize(0, 2);
        int device = uil.Scan(uilPointer);
        System.out.println("Device found: " + device);
    }   
}

我在第一次服务电话中将数据插入用户名，电子邮件和密码：

var user = new mongoose.Schema({

  username : {type: String},
  email    : {type: String,index: {unique: true}},
  password : {type: String},
  feed     : [{
                title       : {type: String},
                description : {type: String},
                latitude    : {type:Number},
                longitude   : {type:Number},
                feedImages  : [{imageUrl: {type: String}}]
             }]
});

然后我尝试将数据插入到上述id的Feed中。

app.post('/users',function(req,res) {

    var username = req.body.username;
    var email    = req.body.email;
    var password = req.body.password;

    var userData = {'username':username,'email':email,'password':password};
    new db.user(userData).save(function(err,result){
      if (err) {
         res.json({"success": '0', "message": "Error adding data"});
        }
      else {
             res.json({"success": '1', "message": "Data added"});
        }
     });
 });

未显示错误，但未插入数据。

您的纬度和经度应转换为数字：

var latitude    = Number(req.body.latitude);
var longitude   = Number(req.body.longitude);

MongoDB插入不起作用
