Question

我尝试创建包含对象数组的mongoose模式。架构看起来像：

const mapSchema = new Schema({
  name: {
    type: String
  },
  description: {
    type: String
  },
  rate: {
    type: Number,
    default: 0
  },
  sumOfRates: {
    type: Number,
    default: 0
  },
  places: [
    {
      name: String,
      description: String,
      difficulty: { type: String, default: 0 },
      sumOfRates: { type: String, default: 0 },
      lat: Number,
      lng: Number
    }
  ]
}, {
  timestamps: true
})

位置是对象数组。我尝试创建mongoose模式并将其用作places数组的元素（places：[ref：＆＃39; placeSchema＆＃39;]）。

const placeSchema = new Schema({
  name: {
    type: String
  },
  description: {
    type: String
  },
  difficulty: {
    type: Number,
    default: 0
  },
  lat: {
    type: Number
  },
  lng: {
    type: Number
  }
})

但我认为它会在mongo（places文档）中创建另一个separeted文档。可以？我试图避免这种情况将其保存在一个文档中。现在（上面粘贴的代码），给我一个错误，当我尝试在邮递员中插入json时：

{
    "name": "ergergergg",
    "description": "rgergrg",
    "places": [
        {
            "name":"cvcv",
            "description":"rgergrg",
            "lat":233,
            "lng":232
        }]
}

错误：

ValidationError: places: Cast to Array failed for value "[object Object]" at path "places"

为什么会有这样的错误？如何解决这个问题？

适当的方法是使用子模式。

const subSchema = new Schema({
  name: {
    type: String,
  },
  description: {
    type: String,
  },
  difficulty: {
    type: Number,
    default: 0,
  },
  lat: {
    type: Number,
  },
  lng: {
    type: Number,
  },
});

const mapSchema = new Schema({
  name: {
    type: String,
  },
  description: {
    type: String,
  },
  rate: {
    type: Number,
    default: 0,
  },
  sumOfRates: {
    type: Number,
    default: 0,
  },
  places: [subSchema],
}, {
  timestamps: true
});

插入新数据

mapSchema.insert({
   name: "ergergergg",
   description: "rgergrg",
   places: [
        {
            name: "cvcv",
            description": "rgergrg",
            lat: 233,
            lng: 232,
        },
   ],
});

要使 subSchema 可选，您可以这样做@DanMossa :

function onEditAdded(e) {
  var activeSheet = e.source.getActiveSheet();
  if (activeSheet.getName() == "New Hires") {
    var aCell = e.source.getActiveCell(), col = aCell.getColumn();
    if (col == 20) {
      var dateCell = aCell.offset(0,1);
      if (aCell.getValue() === true) {
        var email = Session.getActiveUser().getEmail();
          Logger.log(email);
        dateCell.setValue(email);
      } else {
        dateCell.setValue("");
      }
    }
  }
}

Mongoose，使用对象数组表达创建模式
