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
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)
}
}
});
return User;
};
// CONFIG MODEL
module.exports = function(sequelize, DataTypes) {
var Config = sequelize.define('Config', {
notifications : DataTypes.INTEGER
}, {
classMethods : {
associate : function(models) {
Config.belongsTo(models.User)
}
}
});
return Config;
};
As you can see, a "user" has one "config" and a "config" belongs to a "user", so after a user is created I want to create his config row automatically.
The goal is to do:
DELIMITER //
CREATE TRIGGER create_config AFTER INSERT ON user
FOR EACH ROW
BEGIN
insert into config (user_id) values(new.user_id);
END; //
DELIMITER ;
Now, what I do to simulate that is the following:
.then(function(user){
return dao.Config.create(req.body, user, t);
})
Once a User is created I create his configuration like that... it works but is not what I'm searching.
How would I do it?
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;
};
