get .findOrCreate() error

Question

I'm using Sequelize as ORM. Here's my user model:

###
    User model
###
User = exports.User =  globals.sequelize.define "User",
    username: globals.Sequelize.STRING
    email:
        type: globals.Sequelize.STRING
        validate:
            isEmail: true
    hash:     globals.Sequelize.STRING
    salt:     globals.Sequelize.STRING(512)
    fname:    globals.Sequelize.STRING
    lname:    globals.Sequelize.STRING
    country:  globals.Sequelize.STRING

I'm saving user:

globals.models.User.findOrCreate
    username: "johny"
    password: "pass"
    email: "johny93[###]example.com"
.success (user, created)->
    console.log user.values
    res.send 200
.error ->
    console.log err # how to catch this?
    res.send 502

If email is valid (email: "[email protected]"), everything works great. But if email fails validation (as in the example above), I get an insertion error. How to catch error type? .error method can't get any error parameters.

Answer 1

 User.findOrCreate({
  where: {
    username: "johny",
    password: "pass",
    email: "johny93[###]example.com"
  },
  defaults: {
    //properties to be created 
  }
}).then(function(user){
  var created = user[1];
  user = user[0];
  console.log(user.values);
}).fail(function(err){
   console.log('Error occured', err);
});

EDIT: as @Domi pointed out, better way is to use 'spread' instead of 'then'

User.findOrCreate({
  where: {
    username: "johny",
    password: "pass",
    email: "johny93[###]example.com"
  },
  defaults: {
    //properties to be created 
  }
}).spread(function(user, created){
  console.log(user.values);
}).fail(function(err){
   console.log('Error occured', err);
});

sequelize will pass the error as the paramater to the error function.

JavaScript:

User.findOrCreate({username: "johny",password: "pass",email: "johny93[###]example.com"})
.success(function(user, created){
    console.log(user.values);
    res.send(200);
})
.error(function(err){
   console.log('Error occured' + err);
})

CoffeScript:

globals.models.User.findOrCreate
    username: "johny"
    password: "pass"
    email: "johny93[###]example.com"
.success (user, created)->
    console.log user.values
    res.send 200
.error (error)->
    console.log error # how to catch this?
    res.send 502
