Question

What is the difference between

// \'this\' is the controller
this.get(\'model\').save();

and

Answer 1

Which one should I use?

I'd recommend using this.get('model').save()

what's the main difference between this.get('store').scheduleSave(this) and this.get('store').commit()?

If you are saving many records during the same run loop, scheduleSave will batch changes so that multiple records will get saved in the same transaction. In some cases commit might cause changes to other records to be persisted.
