使用貓鼬和打字稿創建模式

Question

試圖創建新的貓鼬模式，但問題是我總是得到只有兩列的新集合：_id 和 __v。 就是這樣，模式中沒有我的列。 這是架構代碼：

import DataAccess from '../DataAccess';
import IUserModel from '../../model/interfaces/UserModel';

var mongoose = DataAccess.mongooseInstance;
var mongooseConnection = DataAccess.mongooseConnection;
class UserSchema {
  static get schema() {
    var schema = mongoose.Schema({
      email: {
        type: String,
        required: false
      },
      firstName: {
        type: String,
        required: false
      },
      lastName: {
        type: String,
        required: false
      },
      createdAt: {
        type: Date,
        required: false
      }
    });

    return schema;
  }
}

var schema = mongooseConnection.model<IUserModel>('Users', UserSchema.schema);

export default schema;

用戶模型非常簡單：

import mongoose = require('mongoose');

interface UserModel extends mongoose.Document {
  email: string;
  firstName: string;
  lastName: string;
  createdAt: Date;
}

export default UserModel;

數據訪問層：

import mongoose = require('mongoose');

class DataAccess {
  static mongooseInstance: any;
  static mongooseConnection: mongoose.Connection;

  static connect(): mongoose.Connection {
    const MONGODB_CONNECTION: string = 'mongodb://localhost:27017/dbname';

    if (this.mongooseInstance) return this.mongooseInstance;

    this.mongooseConnection = mongoose.connection;
    this.mongooseConnection.once('open', () => {
      console.log('Connected to mongodb');
    })
    this.mongooseInstance = mongoose.connect(MONGODB_CONNECTION);
    return this.mongooseInstance;
  }
}

DataAccess.connect();
export default DataAccess;

一旦我嘗試創建新用戶，它就會在數據庫中創建新文檔，但只有兩個默認列......

我的錯，代碼沒問題，但問題在於通過 google chrome 中的郵遞員擴展將值發布到服務器。 只需添加 Content-Type = application/json。 就是這樣。 猜猜我現在可以關閉這個問題了。
