it helps some times I am developing small app using express.js and sequelize. Now I have a problem. I go with this tutorial and stucked. , The bug is in models/index.js. In there you have:

code :

...
.filter(function(file) {
  return (file.indexOf('.') !== 0) && (file !== basename) && (file.slice(-3) === '.js');
})
...

console.log('KEYS TO models: ' + JSON.stringify(Object.keys(models)));

Sequelize Express multiple models

fixed the issue. Will look into that further I can't seem to figure out how to include multiple models. , At first glance, you can use eager loading with multiple models:

code :

models.TabConfig.findAll({
    include: [{
        model: models.ServerConfig,
        include: [models.Points]
    }]
})

[{
    some: 'tab',
    saved: 'property',
    Servers: [{
        some: 'server',
        saved: 'property',
        Points: [...]
    }, ...]
}, ...]

Different ways to define models in Sequelize

hope this fix your issue For the purpose of the static code analysis utility I've started to build, I assume the define() method is always used to define the models.
The only thing you should take into account is that there are 2 general ways to define model fields:

code :

sequelize.define('Locale', {
    locale: DataTypes.STRING
});

sequelize.define('Locale', {
    locale: {
        type: DataTypes.STRING
    }
});

The ambiguous error occurs while using the models.sequelize.col () in the include in sequelize(node.js express)

will be helpful for those in need Appearently both Board and Comment have a _no column? In that case you need to specify which one you want to count, fx: models.sequelize.col('board._no')) (make sure the table name matches the pluralization and capitalization of the table in the rest of the query)

With these it helps Im using sequelize /w node and node-mysql. , In the part where u define sequelize

code :

var sequelize = new Sequelize('database', 'username', 'password', {
  define: {
    charset: 'utf8',
    collate: 'utf8_general_ci', 
    timestamps: true
  },
  logging:false
});

sequelize.define('songs', {
  name: DataTypes.STRING,
  link: DataTypes.STRING,
  artist: DataTypes.STRING,
  lyrics: DataTypes.TEXT,
  writer: DataTypes.STRING,
  composer: DataTypes.STRING
}, {
  charset: 'utf8',
  collate: 'utf8_unicode_ci'
});

express and sequelize - load unrelated models in same route

help you fix your problem So based on what I see, I think that you lack some understanding of promises.
This part of the code:

code :

bus.findAll({include: [{model: family, include: [person]}]})
      .then(buses => buses.map(addCount))

volunteerType.findAll()

.then(volunteerTypes => volunteerType.findAll())

exports.get = (request, response) => {
    return Promise.all([
        // Grab and mutate busses
        bus.findAll({
            include: [{
                model: family, include: [person]
            }]
        }).
        then(buses => buses.map(addCount)),
        // grab volunteerType
        volunteerType.findAll()
    ]).
    // This now returns an Array with the resolution of each promise
    then( ([busses, volunteerType]) =>  
        response.render('pages/register', {
            buses, 
            volunteerTypes
        })
    )
};
