Question

我已经定义了一个具有另一个模式数组的Mongose模式，如下所示：

属性架构/模型：

.element {
  background-color: rgba(0,0,0,.1);
  background-image: url('images/filter/grunge.png');
}

客户架构/模型：

import mongoose from 'mongoose';

const PropertySchema = new mongoose.Schema({

    name: {
        type: String
    },
    description: {
        type: String
    },
    value: {
        type: mongoose.Schema.Types.Mixed
    },
    unit: {
        type: String
    },
});

export default mongoose.model('Property', PropertySchema);

生成测试数据：

import mongoose from 'mongoose';

import { PropertySchema } from './Property';

const CustomerSchema = new mongoose.Schema({

    name: {
        type: String,
        required: true,
        unique: true
    },
    description: {
        type: String
    },
    properties: {
        type: [PropertySchema]
    },
    deleted: {
        type: Boolean
    },
});

CustomerSchema.statics.createTestInstance = function(name, description, properties, callback) {

        let personnel = new this ({
            name: name,
            description: description,
            properties: properties,
            deleted: false
        });

        personnel.save(callback);
}

export default mongoose.model('Customer', CustomerSchema);

结果：

function getRandomProperty() {

    let rand = Math.floor(Math.random() * 1000);
    let type = Math.floor(Math.random() * 4);
    let typeArray = [ 124, 2.345, 'Test', true];
    let unitArray = [ null, 'inches', 'certification', 'existance']

    let prop = {};

    prop.name = 'Random Property ' + rand;
    prop.description = 'Description Property ' + rand;
    prop.value = typeArray[type];
    prop.unit = unitArray[type];

    return prop;
}

function generateTestCustomer(name, description) {

    let props = [];
    for (let i = 0; i < 10; i++)
        props.push(getRandomProperty());

    CustomerModel.createTestInstance(name, description, props, function (err) {

        if (err)
            throw new Error('ERROR => Error creating test Customer: ' + err);

        console.log('LOG => Test Customer created: ' + name);
    });
}

为Property生成的数组似乎很好，但是我不知道为什么mongoose会抛出这个错误。

您已将属性架构导入客户模型：

import { PropertySchema } from './Property';

...但您尚未导出属性架构。

您只导出了属性模型。

创建模式实例时，Mongoose Cast to Array的值失败
