ExpressJS - Sequelize - 無法識別的數據類型

Question

我手動創建了一個sql數據庫，現在正試圖設置我的sequelize模型來匹配我的sql表中的列，但是我遇到了與我的模型有關的無法識別的問題字段類型。我似乎無法查明錯誤，以及它是否與我的數據庫中字段的數據類型不匹配，或者sequelize無法識別我的一些代碼。

這是我的錯誤：

/Users/user/Desktop/Projects/node/assistant/node_modules/sequelize/lib/model.js:90 
     throw new Error('Unrecognized data type for field ' + name); 
      ^

這裏是我的模型：

var Sequelize  = require('sequelize'); 
var sequelize = new Sequelize('db', 'admin', 'pwd', { 
    host: 'database-host', 
    port: 3306, 
    dialect: 'mysql' 
}); 


var Images = sequelize.define('images', { 
    pattern: { 
     type: sequelize.STRING, 
     field: 'pattern' 
    }, 
    color: { 
     type: sequelize.STRING, 
     field: 'color' 
    }, 
    imageUrl: { 
     type: sequelize.STRING, 
     field: 'imageUrl' 
    }, 
    imageSource: { 
     type: sequelize.STRING, 
     field: 'imageSource' 
    }, 
    description_id: { 
     type: sequelize.INTEGER, 
     field: 'description_id' 
    } 
}); 

module.exports = Images;

我覺得你的代碼應該是：

var Sequelize  = require('sequelize'); 
var sequelize = new Sequelize('db', 'admin', 'pwd', { 
    host: 'database-host', 
    port: 3306, 
    dialect: 'mysql' 
}); 


var Images = sequelize.define('images', { 
    pattern: { 
     type: Sequelize.STRING, 
     field: 'pattern' 
    }, 
    color: { 
     type: Sequelize.STRING, 
     field: 'color' 
    }, 
    imageUrl: { 
     type: Sequelize.STRING, 
     field: 'imageUrl' 
    }, 
    imageSource: { 
     type: Sequelize.STRING, 
     field: 'imageSource' 
    }, 
    description_id: { 
     type: Sequelize.INTEGER, 
     field: 'description_id' 
    } 
}); 

module.exports = Images; 

你可以參考http://docs.sequelizejs.com/en/latest/api/datatypes/，http://docs.sequelizejs.com/en/latest/docs/models-definition/或這裏的一個例子：https://github.com/thanhson1085/angular-admin-seed/blob/master/server/models/user.js
