Mysql Sequelize.js Node.js：如何传递已经创建的对象来创建多对多关系？

从本帖：

答案仅在您创建个人和电子邮件时显示，但是，我希望使用已创建的电子邮件创建个人

正确创建个人和电子邮件的原始答案：

models.Individual.create({
  name: "Test"
}).then(function(createdIndividual) { // note the argument
  models.Email.create({
    address: "test@gmail.com"
  }).then(function(createdEmail) { // note the argument
    createdIndividual.addEmail(createdEmail)
      .then(function(addedEmail) { // note th-- well you get the idea :)
        console.log("Success");
      });
  })
});

要使用已创建的电子邮件创建个人，我将其修改为：

models.Individual.create({
  name: "Test"
}).then(function(createdIndividual) { // note the argument
    //This email id exists in the Email table.
    var email = {
        id: 1
    }
    createdIndividual.addEmail(email)
    .then(function(addedEmail) {
        console.log("Success");
    });
});

然后我得到了这个错误：

我认为这个错误是因为我的电子邮件对象不是Sequelize对象

心中的问题：

我们是否应该通过电子邮件模型的查询将电子邮件对象转换为Sequalize对象？行吗

考虑到干净的代码和性能，将该对象转换为Sequalize的更好方法是什么

如果我在创建新产品时有多封电子邮件要添加到个人电子邮件中，该怎么办？喜欢超过1个电子邮件ID

请帮忙给我一些建议。谢谢

你是对的，问题是电子邮件不是sequelize对象。若您在添加它之前从数据库中检索它，那个么它就可以工作了。另一方面，sequelize允许您按id设置childs。因此您可以执行以下操作：

models.Individual.create({
  name: "Test"
}).then(function(createdIndividual) {
    createdIndividual.setEmails([emailIds]) //emails id array
    .then(function() {
        console.log("Success");
    });
});

请看这个。
