Mongodb 如何查找Mongoose数组元素的schemaType

我试图从下面的代码中检索模式类型

请帮助我将架构类型获取为字符串数组

我的模式如下：

export const meetingSchema = new Schema({
  MT_meetingType: String,
  MT_meetingFormat: String, 
  MT_meetingFormatSecond: String,
  MT_meetingFormatSecondInput:  String, 
  MT_meetingFormatInput: String,`enter code here`
  MT_meetingNumber: String,
  MT_location: String,
  MT_requestedBy: [String], })

我正在迭代模式中的所有元素，如下所示：

 const keys = Object.keys(Meeting.schema.paths);



     for (const index in keys) { 
            console.log('keys index ', keys[index], typeof keys[index]);
        }

export const meetingSchema = new Schema({
  MT_meetingType: { type: String },
  MT_meetingFormat: { type: String }, 
  MT_meetingFormatSecond: { type: String },
  MT_meetingFormatSecondInput:  { type: String }, 
  MT_meetingFormatInput: { type: String },
  MT_meetingNumber: { type: String },
  MT_location: { type: String },
  MT_requestedBy: [{ type: String }]
 });

但是，当我试图检索由请求的

MT_类型时，它将以字符串的形式出现，而不是
[String]

如何解决此问题？
创建类似以下内容的模式：

 const keys = Object.keys(Meeting.schema.paths);



     for (const index in keys) { 
            console.log('keys index ', keys[index], typeof keys[index]);
        }

export const meetingSchema = new Schema({
  MT_meetingType: { type: String },
  MT_meetingFormat: { type: String }, 
  MT_meetingFormatSecond: { type: String },
  MT_meetingFormatSecondInput:  { type: String }, 
  MT_meetingFormatInput: { type: String },
  MT_meetingNumber: { type: String },
  MT_location: { type: String },
  MT_requestedBy: [{ type: String }]
 });

现在做你正在做的。
希望对您有所帮助。
