Question

I would like to be able to call save() on a backbone model and have the backend return the entire collection of this model instead of only the changed attributes of the model. I would then like backbone to update the entire returned collection. The use case for this is the following:

A user has multiple addresses and can choose a shipping address from this collection. If she chooses a different shipping address from the collection the previous shipping address should be updated to the state of ‘just another plain address’. For this the entire collection has to be updated instead of only the changed model.

Is this somehow possible in backbone.js?

Thanks a lot in advance!

Answer 1

models that are bound to collections, contain their collection parent as a property. Also, since your returning a list of models, we can assume that it is always in a list.

mymodel = Backbone.Model.extend({
   parse: function (data) {
     if(this.collection && typeof(data) === 'array') {
        this.collection.reset(data);
     }
     return data;
   }
});
