For example:
class User extends Spine.Controller
@configure 'User', 'name'
@extend Spine.Model.Ajax
@url: '/save'
user = new User(name: 'test')
user.save()
User.bind 'update', (item) ->
console.log(item.flag) # undefined
say '/save' response {flag: 0}
because of some database error, when Ajax finished, Spine trigger the update event and update the user
model, but there is no flag
property extended to user
when updated. So, how can I handle this situation when I need to response some extra data that is a little different from model?
After reading the document more carefully, I found the answer: see http://spinejs.com/docs/ajax [Custom serialization]
