Chaining waterline calls with Promises - orm

Question

I have been hitting my head off a wall on this for the last 3 days.
I am using sailsjs & the waterline ORM that comes bundled. I want to run DB calls one after an other. I know I can do this by nesting inside "then" calls but it just looks wrong.
I have gone over the Q documentation and tutorials several times but I still don't get how to connect and fire "then" calls from existing Promises sequentially :(
I want to:
create a user
create a action
link the user & action
update the user
update the action
My code looks like
var mail = 'test#test.com';
Users.create({email:mail, name:''}).then(console.log).fail(console.log);
Actions.create({actionID:123})
.then(function(error, action){
Users.findOneByEmail(mail).then(function(person){
person.actions.add(action.id);
person.save(console.log);
}).fail(console.log)
});
Users.update({email:mail},{name:'Brian'}).exec(console.log);
Actions.update({actionID:123},{now:'running'}).exec(console.log);
As you can see from the code I've been using a mix of exec & then :P
I think the way is to connect the
Users.create(...).then -> Action.create(...).then -> Users.findOneByEmail(...).then -> *and the updates.
Huge thanks from any help

Answer 1

So after a day's research. I think I've cracked it.
Note: The first version I got working had the "then"s lined-up(removing the pyramid of doom) by returning the create. This allow me to call then on the next line to fire the create. http://documentup.com/kriskowal/q/#tutorial/chaining
Here's my final version
var mail = 'test#test.com';
Users.Create({email:mail,name:''})
.then(function(user){
return [Actions.create({actionID:123}),user];
}).spread(function(action, user){
user.action.add(action.id);
user.name = 'Brian';
user.save();
action.now = 'running';
action.save();
}).catch(console.error);
One of the cool things is the "spread" that allows you to line-up "Promises" and "values" to be return one they all have completed into the next "then".
