Question

我正在尝试使用Sequelize ORM创建到远程数据库的连接。但是出现错误：

> var eventName = msg.name === 'error' ? 'errorMessage' : msg.name
>                       ^

> at Socket.<anonymous> (node_modules\pg\lib\connection.js:120:27) at

> (_stream_readable.js:208:10) at TCP.onread (net.js:597:20)

我正在同步server.js中的Sequelize模型，提供端口并传递控制器和功能。

 models.sequelize.sync().then(() => {
        app.listen(1234);
        app.use('/check', check);
        check.testCheck(() => {
            io.emit('testCheck');
         });
    })

在models / index.js中，这里是Sequelize选项（所有参数均为qorrect含义：用户名密码db等），在这里我也定义了模型（在这种情况下，我只有一个称为“ orders”的模型）

const Sequelize = require('sequelize');
    const sequelize = new Sequelize('db', "username", 'password',    {
      host: 'host',
      dialect: 'postgres',
      port: 1234,
      pool: {
        max: 5,
        min: 0,
        acquire: 30000,
        idle: 10000
      },
         });

  var models = {
    orders: sequelize['import']("./iSOMessagesModel"),
  }; 



Object.keys(models).forEach(modelName => {
  if (models[modelName].associate) {
    models[modelName].associate(models);
  }
});

models.sequelize = sequelize;
models.Sequelize = Sequelize;

module.exports = models;

模型如下：

module.exports = function(sequelize, DataTypes) {
  var Orders = sequelize.define('ISOMessages', {
    id: {
      type: DataTypes.STRING,
      primaryKey: true
    },
    message: {
      type: DataTypes.STRING
    },
    createdAt: {
      type: DataTypes.DATE,
    },
    updatedAt: {
      type: DataTypes.DATE,
    },  
    status: {
      type:  DataTypes.STRING
    },
    sResponse: {
      type:  DataTypes.STRING
    },
    userId: {
      type:  DataTypes.INTEGER 
    },
    cardId: {
      type: DataTypes.STRING
    },
    amount: {
      type: DataTypes.INTEGER 
    },
    commission: {
      type: DataTypes.INTEGER 
    },
    location: {
      type: DataTypes.STRING
    },
    provider: {
      type: DataTypes.STRING
    },
    }, {
       tableName: 'ISOMessages'
    });


  return Orders;
}

Thnx

无法读取未定义的Postgres / Sequelize的属性“名称”
