Javascript Mongoose.js CastError:value“的数字转换失败”；{&&x27；$gte&&x27；：1}"；在路径上“；“访问”；对于“型号”；“项目”；

我试图在一组用户中找到一个用户，这些用户的id与我的令牌中的id相同，访问权限大于1

为此，我使用了以下代码，但我得到了一个CastError：

Project.findOne({ Users: {User: decoded._id, access: { $gte: authStatus }}, _id: id })
        .then((result) => {
            console.log(result)
        })
        .catch((err) => {
            console.log(err)
        });

    CastError: Cast to Number failed for value "{ '$gte': 1 }" at path "access" for model "Projekt"

我的模式：

const ProjectSchema = new Schema(
{
    Users: [
        {
            User: { type: mongoose.Schema.Types.ObjectId, ref: 'usertemps' },
            access: { type: Number, required: true }

    ],
    name: { type: String, required: true },
    deadline: { type: Date, required: true }
},
{
    timestamps: true
}
);

卡斯特罗：

        .then((result) => {
            console.log(result)

这样做可能吗？还是我的做法完全错了

希望有人能帮助您，谢谢您的时间。

要查询嵌套字段，您应该使用

Project.findOne({
“Users.User”：已解码。_id，
“Users.access”：{$gte:authStatus}，
_id:id，
})
。然后（（结果）=>{
控制台日志（结果）；
})
.catch（（错误）=>{
控制台日志（err）；
});

编辑：

为了过滤数组中的元素并仅返回符合特定条件的元素，可以使用

$filter

运算符
