如何設置主鍵類型與此命令通過<a href="https://github.com/sequelize/cli" rel="nofollow noreferrer">Sequelize CLI</a>通過Sequelize CLI到UUID

Question

我創建一個DB模式：

sequelize model:create --name User --attributes "firstname:string, lastname:string" 

這將創建相應的遷移腳本：

'use strict'; 
module.exports = { 
    up: function(queryInterface, Sequelize) { 
    return queryInterface.createTable('Users', { 
     id: { 
     allowNull: false, 
     autoIncrement: true, 
     primaryKey: true, 
     type: Sequelize.INTEGER 
     }, 
     firstname: { 
     type: Sequelize.STRING 
     }, 
     lastname: { 
     type: Sequelize.STRING 
     }, 
     createdAt: { 
     allowNull: false, 
     type: Sequelize.DATE 
     }, 
     updatedAt: { 
     allowNull: false, 
     type: Sequelize.DATE 
     } 
    }); 
    }, 
    down: function(queryInterface, Sequelize) { 
    return queryInterface.dropTable('Users'); 
    } 
}; 

如圖所示，主鍵被設置爲integer。

有沒有一種方法可以讓CLI默認使用UUID？

Answer 1

您必須手動編輯生成的文件，將Sequelize.INTEGER更改爲Sequelize.UUID，然後刪除autoIncrement: true屬性幷包含此defaultValue: uuid()。

npm install uuid

所以，你的模型應該是這樣的：

const uuid = require('uuid/v4'); // ES5 

'use strict'; 

module.exports = { 
    up: function(queryInterface, Sequelize) { 
    return queryInterface.createTable('Users', { 
     id: { 
     allowNull: false, 
     primaryKey: true, 
     type: Sequelize.UUID, 
     defaultValue: uuid() 
     }, 
     firstname: { 
     type: Sequelize.STRING 
     }, 
     lastname: { 
     type: Sequelize.STRING 
     }, 
     createdAt: { 
     allowNull: false, 
     type: Sequelize.DATE 
     }, 
     updatedAt: { 
     allowNull: false, 
     type: Sequelize.DATE 
     } 
    }); 
    }, 
    down: function(queryInterface, Sequelize) { 
    return queryInterface.dropTable('Users'); 
    } 
};
