Question

我正在为我的前端应用程序使用mongoose，mongoDb和expressjs编写小型REST API。我有问题保存布尔数组对象。其他数组对象按预期保存在数据库中，但布尔值除了第一个数组值外，还得到意外的id而不是值。这是我的代码：模型架构：

const companiesSchema = mongoose.Schema({
    _id: mongoose.Schema.Types.ObjectId,
    benefitsOffers: [
        {
        balance : Boolean
        },
         {
        car: Boolean
        },
        {
        bonseModel: Boolean
        }, 
        {
        centerlaOffice: Boolean
        }, 
        {
        owenerShip: Boolean
        }, 
       ]
})
module.exports = mongoose.model('Companies', companiesSchema);

Postman发送的测试值

    {

     "benefitsOffers": [
        {
            "balance": true

        },

        {
            "car": false

        },
        {
            "bonseModel": true

        },
        {
            "centerlaOffice": true

        },
        {
            "owenerShip": true

        },
]

}

服务器响应

 {
    "_id": "5ad93a2bd60c32622a8fce1d",
      "benefitsOffers": [
                {
                    "_id": "5ad93a2bd60c32622a8fce34",
                    "balance": true
                },
                {
                    "_id": "5ad93a2bd60c32622a8fce33"
                },
                {
                    "_id": "5ad93a2bd60c32622a8fce32"
                },
                {
                    "_id": "5ad93a2bd60c32622a8fce31"
                },
                {
                    "_id": "5ad93a2bd60c32622a8fce30"
                },

    }

我有其他数据类型的类似数组结构，没有问题。我错过了什么？，我引用了官方文档，它没有任何关于布尔数组对象的具体事情。我只是需要某人查明我的错误

这是一个解决方案

创建 benefitsOffers作为单独的架构

const benefitsOffersSchema =  new Schema({
    balance : { type : Boolean, default: false },
    car : { type : Boolean, default: false },
    bonseModel : { type : Boolean, default: false },
    centerlaOffice : { type : Boolean, default: false },
    owenerShip : { type : Boolean, default: false }
});

将 benefitsOffersSchema附加到companiesSchema

const companiesSchema = mongoose.Schema({
    benefitsOffers : [benefitsOffersSchema]
})
const Companies = mongoose.model("Companies",companiesSchema);
module.exports = Companies;

现在您可以插入布尔值

var benefitsOffers = {
    balance : true,
    car : true,
    bonseModel : false,
    centerlaOffice : false,
    owenerShip : false
};
var company = new Companies({ benefitsOffers : benefitsOffers});
company.save();

下方是插入文档的输出

mongoose上的布尔字段没有设置值
