node.js - Sequelizer 连接多个 hasMany 关联

Question

我正在关注官方的 Sequelizer 文档，但我无法让它与多个“hasMany”关联一起工作。

下面的代码呈现错误:Unhandled rejection Error: [object Object] is not associated to User!
这是如何正确完成的？

模型/用户.js

module.exports = function(sequelize, DataTypes) {
  var User = sequelize.define("User", {
    username: DataTypes.STRING
  }, {
    classMethods: {
      associate: function(models) {
        User.hasMany(models.Movie, models.Book)
      }
    }
  });

  return User;
};

路线/index.js

var models  = require('../models');
var express = require('express');
var router  = express.Router();

router.get('/', function(req, res) {
  models.User.findAll({
    include: [ models.Task, models.Movie ]
  }).then(function(users) {
    res.render('index', {
      title: 'Sequelize: Express Example',
      users: users
    });
  });
});

module.exports = router;

发现问题，您必须单独定义它们(例如 User.hasMany 两次)

module.exports = function(sequelize, DataTypes) {
  var User = sequelize.define("User", {
    username: DataTypes.STRING
  }, {
    classMethods: {
      associate: function(models) {
        User.hasMany(models.Movie),
        User.hasMany(models.Books)
      }
    }
  });

  return User;
};
