Mongoose Schema数组：CastError：对于值＆＃34; [object Object]＆＃34;而且＃14; [object object]＆＃34;在路上

Question

我有以下架构，当我要更新它时，我被提到异常。

我在这里看到了几个问题，但仍然有点不清楚我在哪里犯了错误。

模式

var DishSchema = new mongoose.Schema({
  user: { type: mongoose.Schema.Types.ObjectId, ref: 'User' },
  dishes: [ {
    name: { type: String, index: { unique: true } , required:true },
    type: String,
    descdish: String,
    servingtype: String,
    servingquantity: Number,
    cuisine: String,
    features: [ { type: String } ],
    dishphotos: {
      mainphoto: String,
      secphoto: String,
      thirdphoto: String
    },
    price: Number,
    discount: {
      offer: {type: Boolean ,  default: false },
      discoutamount: String,
      from: Date,
      to: Date
    },
    availability: {
      advancebooking: {
        mindish: Number,
        orderby: String
      },
      premake: {
        from: Date,
        to: Date,
        aftertime: String,
        orderby: String,
        quantity: Number
      },
      regulardishes: [
        {
          weekday: String,
          orderby: String,
          readyby: String,
          readyday: String,
          pickfrom: String,
          pickto: String,
          qty: Number
        }
      ]
    }  
  } ] 
});

在执行mongo语句之前，我将值存储在var / record中，如下所示。

  var docId = req.body.userid;
  var query = { user: docId };   

  var dishRecord = {  
    name : req.body.name || "" , 
    type : req.body.type || "",  
    descdish : req.body.descdish || "", 
    servingtype : req.body.servingtype || "", 
    servingquantity : req.body.servingquantity || "", 
    cuisine : req.body.cuisine || "", 
    features : req.body.features || "", 
    dishphotos : req.body.dishphotos || "",        
    price : req.body.price || "", 
    discount : req.body.discount || "",       
    availability : {
      advancebooking :  req.body.availability.advancebooking || "",   
      premake : req.body.availability.premake || "",
      regulardishes : req.body.availability.regulardishes || [] 
    }       
  }  

然后我跑

Dish.findByIdAndUpdate(
     docId,
     { $push: {"dishes": dishRecord}},
     {  safe: true, upsert: true},
       function(err, model) {
         if(err){
          console.log("Dish DB Error::: ", err);
          return res.send(err);
         }
         console.log( "Dish DB updated");
          return res.json(model);
});

异常
