使用sequalize sequalize-auto關聯問題

Question

我使用sequelize-auto從數據庫創建模型。但是我無法使用包含方法來處理關係。我收到以下錯誤

錯誤：student_details_tbl（studentDetails）未關聯到user_tbl！

這是我的模型和數據庫連接。

數據庫連接

var config  = require('./config'); 
var Sequelize = require('sequelize'); 

var db   = new Sequelize(config.dbConn.database, config.dbConn.user, config.dbConn.password,{ 
    dialect  : config.dbConn.dialect, 
    host  : config.dbConn.host, 
    port  : config.dbConn.port, 
    pool  : config.dbConn.pool, 
    define  : { 
     timestamps: false 
    } 
}); 

db.sync(); 


db.Sequelize = Sequelize; 

module.exports = db; 

user_tbl：

module.exports = function(sequelize, DataTypes) { 
    return sequelize.define('user_tbl', { 
    id: { 
     type: DataTypes.INTEGER(11), 
     allowNull: false, 
     primaryKey: true, 
     autoIncrement: true 
    }, 
    firstName: { 
     type: DataTypes.STRING, 
     allowNull: true 
    }, 
    lastName: { 
     type: DataTypes.STRING, 
     allowNull: true 
    }, 
    loginId: { 
     type: DataTypes.STRING, 
     allowNull: true 
    }, 
    password: { 
     type: DataTypes.STRING, 
     allowNull: true 
    }, 
    created: { 
     type: DataTypes.DATE, 
     allowNull: true, 
     defaultValue: sequelize.literal('CURRENT_TIMESTAMP') 
    }, 
    modified: { 
     type: DataTypes.DATE, 
     allowNull: true, 
     defaultValue: sequelize.literal('CURRENT_TIMESTAMP') 
    } 
    }, { 
    tableName: 'user_tbl' 
    }); 
}; 

student_details_tbl：

module.exports = function(sequelize, DataTypes) { 
    return sequelize.define('student_details_tbl', { 
    id: { 
     type: DataTypes.INTEGER(11), 
     allowNull: false, 
     primaryKey: true, 
     autoIncrement: true 
    }, 
    userId: { 
     type: DataTypes.INTEGER(11), 
     allowNull: true, 
     references: { 
     model: 'user_tbl', 
     key: 'id' 
     } 
    }, 
    barcode: { 
     type: DataTypes.INTEGER(13), 
     allowNull: false 
    }, 
    rollNumber: { 
     type: DataTypes.STRING, 
     allowNull: false, 
     defaultValue: '' 
    }, 
    created: { 
     type: DataTypes.DATE, 
     allowNull: true, 
     defaultValue: sequelize.literal('CURRENT_TIMESTAMP') 
    }, 
    modified: { 
     type: DataTypes.DATE, 
     allowNull: true, 
     defaultValue: sequelize.literal('CURRENT_TIMESTAMP') 
    } 
    }, { 
    tableName: 'student_details_tbl' 
    }); 
};

「有些時候你可能要參考其它表，不添加任何約束或協會。在這種情況下，您可以手動將參考屬性添加到您的架構定義中ition，並標記它們之間的關係。「

因此，通過引用屬性，您不會在DataBase中創建模型關係。你應該像HasOne，屬於關聯classMethods使用副......
