Question

我正在为Node.js测试不同的ORM，并且遇到了这个错误：

Possibly unhandled TypeError: undefined is not a function
@ person.setUser(user);

尝试person.setUsers，user.setPerson和user.setPeople。还试过console.log找不到运气的功能。

我做错了什么？

var config = require('./config.json');
var Sequelize = require('sequelize');
var sequelize = new Sequelize(config.connection, {
    define: {
        freezeTableName: true,
        underscoredAll: true,
        underscored: true
    }
});

var Person = sequelize.define('person', {
    first_name: Sequelize.STRING,
    last_name: Sequelize.STRING
});

var User = sequelize.define('user', {});

Person.hasOne(User);

sequelize.sync().then(run);

function run() {
    var person = Person.create({ first_name: 'Markus', last_name: 'Hedlund' });
    var user = User.create();

    person.setUser(user);
}

Answer 1

我认为你想要做的是

Person.create({ first_name: 'Markus', last_name: 'Hedlund' }).then((person) => {
      User.create().then((user) => {
           person.setUser(user);
      });
});

Answer 2

虽然dege的答案是正确的，但我会用一个很好的承诺链写出来：

Person.create({ first_name: 'Markus', last_name: 'Hedlund' })
.bind({})
.then(function(person){
    this.person = person;
    return User.create()
})
.then(function(user){
    return this.person.setUser(user);
});

在Sequelize中创建包含与hasOne关联的行
