Is it possible to initialise a backbone Collection with object IDs rather than objects?

Viewed 19289

I have a Backbone.js Collection and I have an array of model IDs that I want to populate it. I know that I could fetch these objects one by one, build an array of objects and pass them into the Collection's constructor as an array.

What I'd like to be able to do is pass the array of object ids into the constructor as initial data, and get the Collection to fetch them, possibly as batch, as per this.

Doable?
