Question

尝试创建新的mongoose模式，但问题是我总是只使用两列来获取新集合：_id和__v。就是这样，没有我的架构列。这是架构代码：

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;

用户模型非常简单：

import mongoose = require('mongoose');

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

export default UserModel;

数据访问层：

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;

尝试创建新用户后，它会在数据库中创建新文档，但只有两个默认列...

我的错，代码还可以，但问题在于通过google chrome中的postman扩展名向服务器发布值。只需要添加Content-Type = application / json。就是这样。我猜我现在可以关闭这个问题了。

使用mongoose和typescript创建模式
