使用包含和属性进行续集 - 超时错误

Question

当我尝试使用我的包含模型中的属性时收到超时错误，我想知道它是否与我尝试包含该属性的方式有关或与我的代码片段无关的问题。

这是我的路线查询（db.Description，正文就是我所说的）：

router.get('/:pattern/:color/result', function(req, res, image){

    console.log(req.params.color);
    console.log(req.params.pattern);

    db.Images.findAll({ 
        where: {
            pattern: req.params.pattern,
            color: req.params.color
        },
        include: [{model: db.Description, attributes: 'body'}],
        attributes: ['id', 'pattern', 'color', 'imageUrl', 'imageSource', 'description_id', 'description.body']
    }).then(function(image){
        //console.log(doc.descriptions_id);
        res.render('pages/suit-result.hbs', {
            pattern : req.params.pattern,
            color : req.params.color,
            image : image
            })
        });
});

这是我的图片模型：

module.exports = function(sequelize, DataTypes){

var Images = sequelize.define('images', {
    pattern: DataTypes.STRING,
    color: DataTypes.STRING,
    imageUrl: DataTypes.STRING,
    imageSource: DataTypes.STRING,
    description_id: DataTypes.INTEGER
}, {
    classMethods: {
        associate: function(db) {
            Images.belongsTo(db.Description, {foreignKey: 'description_id'});
        }
    }
});
    return Images;
}

这是我的描述模型：

module.exports = function(sequelize, DataTypes) {

var Description = sequelize.define('description', {
    description_id: {
        type: DataTypes.INTEGER,
        primaryKey: true
    },
    color: DataTypes.STRING,
    body: DataTypes.STRING
}, {
    freezeTableName: true
});
    return Description;
}

这里是我加入的地方：

var Sequelize      = require('sequelize');
var sequelize = new Sequelize("assistant", "admin", "pwd", {
    host: "site.com",
    port: 3306,
    dialect: 'mysql'
});
var db = {};

db.Description = sequelize.import(__dirname + "/descriptionModel");

db.Images = sequelize.import(__dirname + "/imagesModel");

db.Images.associate(db);

db.sequelize = sequelize;
db.Sequelize = Sequelize;

module.exports = db;

属性选项应该是数组或对象。见 docs.
