Sequelize - sequelize.sync()
Sequelize - sequelize.sync()
提问于 2016-11-10 19:50:06
我不明白指令sequelize.sync()是怎么工作的。这是一个示例：
添加到我的server.js文件中：
db.sequelize.sync().then(function() {
app.listen(PORT);
console.log("Express listen on port: " + PORT);
})并添加到我的db.js文件中，以创建新数据库：
//create a sequelize database for export it into server.js
var Sequelize = require('sequelize');
var sequelize = new Sequelize(undefined, undefined, undefined, {
'dialect': 'sqlite',
'storage': __dirname + '/data/dev-todo-api.sqlite' // location where you create a new sqlite database
});
var db = {};
db.todo = sequelize.import(__dirname + "/models/todo.js");
db.sequelize = sequelize; //contain a settings of database
db.Sequelize = Sequelize;
module.exports = db;在__dirname + "/models/todo.js"中，我创建了我的表/模型。当我启动db.sequelize.sync()时，如何知道我的模型必须存储到数据库中？我从不调用db.todo (仅用于创建模型)
非常感谢你，莫里斯
