在mongoDB和Schema中保存数据的方式如下：>

var StatusSchema = new mongoose.Schema（{

empName: {
    projectName: { type: String },
    clientName: { type: String },
    statusLastWeek: { type: String },
    statusThisweek: { type: String },
    planNextWeek: { type: String }
}
}）;

var Status = mongoose.model('Status', StatusSchema);
module.exports = Status;

  Description: Want save data in MongoDB, data schema is like above mentioned,
   save saving data is sored loke as bellow. 
   Inside Mongo DB :
{ "_id" : ObjectId("5d92f4aba4695e2dd90ab438"), "__v" : 0 }
{ "_id" : ObjectId("5d92f4b4a4695e2dd90ab439"), "__v" : 0 }
MongoDB中的预期集合：

 Dave Smith {
    projectName: BLE Mesh,
    clientName: Tera,
    statusLastWeek: BLE Scan,
    statusThisweek: BLE List View,
    planNextWeek:   Mqtt config
}
Node JS代码：

router.post（'/ update'，（req，res，next）=> {

    userStatus = new wkStatus(req.body)
     userStatus.save()
    .then(status => {
      res.redirect('/success');
      console.log ("Status saved in DB")
    })
   .catch(err => console.log(err))

  // return next;
}）;

var StatusSchema = new mongoose.Schema（{empName：{projectName：{type：String}，clientName：{type：String}，statusLastWeek：{type：String}，statusThisweek：{type：String}，...] >

const wkStatus = new wkStatus({
      _id: new mongoose.Types.ObjectId(),
      projectName: req.body.projectName,
      clientName: req.body.clientName,
      statusThisweek: req.statusThisweek,
      statusLastWeek: req.statusLastWeek,
      planNextWeek: req.planNextWeek
})
Status
   .save()
   .then(result => {
        res.status(201).json({
            message: "Data Created Successfully",
        })
       console.log(result) // show the response
   })
  .catch(err => {
       res.status(500).json({error:err})
  })
尝试这种方式，希望它能起作用。如果需要更多可以给我发消息>
