未定義的續集

我爲我的orm數據庫使用了sequelize。我正在使用mysql。未定義的續集

運行該項目時出現此錯誤。

var accounts = sequelize.define('OkAkun' , {//attrbut 
         ^

ReferenceError: sequelize is not defined 
    at module.exports (/path_to_project/Backend/app/models/OkAkun.js:7:26)

看看我的文件

index.js

"use strict"; 
var fs = require('fs'); 
var path = require ('path'); 
var Sequelize = require ('sequelize'); 
var basename = path.basename(module.filename); 
var env = process.env.NODE_ENV || "development"; 
var dbConfig =require(__base + "config/initializers/config.js").database; 
var sequelize; 

sequelize = new Sequelize(dbConfig[env].database , dbConfig[env].username , dbConfig[env].password, 
      { 
       "dialect": "mysql", 
       "host" :dbConfig[env].host, 
       "port" :dbConfig[env].port, 
       "logging": false, 
       "define": {underscored: true} 
      }); 

var db = {}; 

fs 
.readdirSync(__dirname) 
.filter(function(file){ 
    return (file.indexOf(".") !== 0) && (file !== basename); 
}) 
.forEach(function(file) { 
    var model = sequelize.import(path.join(__dirname,file)); 
    db[model.name] = model; 
}); 

Object.keys(db).forEach(function (modelName){ 
    if("associate" in db[modelName]){ 
     db[modelName].associate(db); 
    } 
}); 

db.sequelize = sequelize; 
db.Sequelize = Sequelize; 



module.exports = db;

，這是我的模型。當我運行該項目。它顯示錯誤，沒有定義的續集。

OkAkun.js

module.exports = function() { 

var accounts = sequelize.define('OkAkun' , {//attrbut 

    id_akun : { 
     autoIncrement: true, 
     type : DataTypes.INTEGER, 
     allowNull: false, 
     primaryKey : true 
    }, 
    username:{ 
     type : DataTypes.STRING, 
     allowNull: false 
    }, 
    phone_number:{ 
     type: DataTypes.STRING, 
     allowNull:false 
    }, 
    email : { 
     type: DataTypes.STRING, 
     allowNull: true 
    }, 
    create_at : { 
     type: DataTypes.DATE, 
     allowNull: false  
    }, 
    update_at : { 
     type : DataTypes.DATE, 
     allowNull: false 
    }, 
    password : { 
     type: DataTypes.STRING, 
     allowNull: false 
    } 
}); 

return accounts; 

};

通知你，我在使用ORM像sequelize數據庫新。而且我不明白我在這裏錯過了什麼。

有什麼想法？
