如何使用 'type' 在 mongoose 中使用嵌套模式来创建数组？

Question

我正在尝试创建一个嵌套的猫鼬模式，它使用“类型”来创建一个嵌套数组。

我认为我遇到问题的架构是“chorePerson”。

这是我试图放入架构中的数据：

{
  "chart": [
    {
      "ordinal": 0,
      "chorePerson": [
        {
          "person": "emily",
          "chore": "Catbox"
        },
        {
          "person": "Steve",
          "chore": "Dishes"
        }
      ]
    }
  ]

这是我当前的架构。注意“chart”和“chorePerson”使用“type”

const mongoose = require('mongoose');
const Schema = mongoose.Schema;

const chorePersonSchema = new mongoose.Schema({
    person: {type: String, requried: true},
    chore: {type: String, required: true},
});


const chartSchema = new mongoose.Schema({
    ordinal: {type: Number, required: true},
    chorePerson:{ type: chorePersonSchema },
});


// create the schema
const ChoreChartSchema = new Schema({

    affiliation: {type: String, required: true},
    currentWeekNumber: {type: Number, required: true},
    currentYear: {type: Number, required: true},

    chart:{ type: chartSchema },

    date: {type: Date, default: Date.now},
})

module.exports = ChoreChart = mongoose.model('cm_chorechart', ChoreChartSchema)

当我运行我的代码时，这是我在崩溃之前得到的：

{ _id: 5c742ed116a095522c38ddfc,
  affiliation: 'family',
   currentYear: 2019,
   currentWeekNumber: 9,
   date: 2019-02-25T20:26:33.914Z,
  chart: [ { ordinal: 0, chorePerson: [Array] } ] }

我认为... chorePerson 导致错误...但我不知道如何解决它。 这是一个例外：

(node:6728) UnhandledPromiseRejectionWarning: ObjectExpectedError: Tried to set nested object field `chart` to primitive value `[object Object]` and strict mode is set to throw.

我的尝试

我试过这个架构：

const chartSchema = new mongoose.Schema({
    ordinal: {type: Number, required: true},

    chorePerson : [{
        person : String,
        chore : String
        }]       
});

更新：

好的...所以我回到了基础，这很有效，但这不是我想要的最终模式。任何人都可以帮忙嵌套这个吗？

// create the schema
const ChoreChartSchema = new Schema({

    affiliation: {type: String, required: true},
    currentWeekNumber: {type: Number, required: true},
    currentYear: {type: Number, required: true},

//    chart:{ type: chartSchema },

    chart:[{
            ordinal: 0,
            chorePerson : [{
                person : String,
                chore : String
            }]
    }],

    date: {type: Date, default: Date.now},
})

事实证明这比我想象的要容易：

    const mongoose = require('mongoose');
    const Schema = mongoose.Schema;

    const chorePersonSchema = new mongoose.Schema({
        person: {type: String, requried: true},
        personID: {type: String, required: true},
        chore: {type: String, required: true},
        choreID: {type: String, required: true},
    });

    const chartSchema = new mongoose.Schema({
        ordinal: {type: Number, required: true},

        chorePerson : [{ type:chorePersonSchema }]       
    });


    // create the schema
    const ChoreChartSchema = new Schema({

        affiliation: {type: String, required: true},
        weekNumber: {type: Number, required: true},
        year: {type: Number, required: true},

        chart:[{type: chartSchema}],

        date: {type: Date, default: Date.now},
    })

    module.exports = ChoreChart = mongoose.model('cm_chorechart', ChoreChartSchema)
