Question

我目前正在从Getting Mean教科书中学习Mean Stack。我在locationSchema上使用子文档时遇到了这个问题。它必须与ref属性相关。我该如何解决这个问题？

var mongoose = require('mongoose');
// reviewSchema
var reviewSchema = new mongoose.Schema({
   author: String,
});
var openingTimeSchema = new mongoose.Schema({
   days: {
      type: String,
      required: true
   }
});
// We use openingTimeSchema as a subdocument here
var locationSchema = new mongoose.Schema({
   name: {
      Type: String,
      required: true
   },

   openingTimes: [openingTimeSchema],
   reviews: [reviewSchema]
});

// Build Mongose Schema to models
mongoose.model('Location', locationSchema);

Error：

TypeError: Undefined type `undefined` at `name.required`
  Did you try nesting Schemas? You can only nest using refs or arrays.

{p> 错误 name属性

var locationSchema = new mongoose.Schema({
   name: {
      Type: String,
      required: true
   },

   openingTimes: [openingTimeSchema],
   reviews: [reviewSchema]
});

应该是：

name: {
   type: String,
   required: true
},

Mongodb给出了嵌套模式的错误
