How to create a TRIGGER in SEQUELIZE (nodeJS)?

Question

I\'m trying to create a trigger using sequelize.. the main idea is to create an instance of CONFIG after creating a USER.

// USER MODEL

You can do this in one of two ways. As you noted, you could create a trigger in the database itself. You could run a raw sequelize query to accomplish this:

sequelize.query('CREATE TRIGGER create_config AFTER INSERT ON users' +
  ' FOR EACH ROW' +
  ' BEGIN' +
  ' insert into configs (UserId) values(new.id);' +
  'END;')

Or, you could create a hook on the user model that performs an action on an afterCreate event:

module.exports = function(sequelize, DataTypes) {    
  var User = sequelize.define('User', {
    name        : DataTypes.STRING(255),
    email       : DataTypes.STRING(255),
    username    : DataTypes.STRING(45),
    password    : DataTypes.STRING(100),
  }, {
    classMethods : {
      associate : function(models) {
        User.hasOne(models.Config)
      }
    },
    hooks: {
      afterCreate: function(user, options) {
        models.Config.create({
          UserId: user.id
        })
      }
    }
  });
  return User;
};
