saving the parent model with blank nested model

[jbhatab]

I am using some form code to create and update a model. This gem has worked great for updating but I need to create a new one and the nested model needs to be blank because the server creates it with an after_save callback.

Does this gem allow for blank nested models or is there something I can do to make that still work?

Have you tried not passing the attribute when creating, or even passing it as null, or empty array? It should work fine:

var post = new Post({
  id: 123,
  title: 'My Title',
  author: null,
  comments: []
})

It's just a an empty collection and seems to be passing itself as nil, but that's raising errors on the rails side.
