Sequelize: Creating To-many Relationships

I am using Sequelize in Node and have a table name User and Auth: User id name Auth: id token I would like to add relationships to this model. A User can have ma

Solution 1:

Give this a try:

var User = sequelize.define('User', {
    ...
    classMethods: {
        associate: function (models) {
            User.hasMany(models.Auth, {as: 'auths'});
        }
    }
};


var Auth = sequelize.define('Auth', {
    ...
    classMethods: {
        associate: function (models) {
            Auth.belongsTo(models.User, {as: 'user'});
        }
    }
};

This'll add a userId column to the auth table.

To query it you'd do (note the include in the query) you can also do it vice-versa:

User.findOne({
    include: [Auth]
})

You might want to check the sequelize docs for one-to-many, hasOne relationships and the hasMany, hasOne API for more info.
