Question

I am wondering if there is any way to get the changed models when passing the add: true to fetch. It renders all the new models in the collection but I’d like to also know if there is any models that changed.

Is this possible?

I also considered the possibility of passing a different function as the success handler to fetch, a function that will re-render only certain portions of the view and not the entire view.

Answer 1

The usual pattern is to have a view that renders your models. You then:

• subscribe in the collection’s view to the collection’s add event in order to append the views of the added models.
• let your models’ views subscribe to the model’s change to re-render.

If you still want to have only one view, you:
– subscribe to the collection’s add event in order to append to the view.
– subscribe to the collection’s change event and update parts of the view.
