Saving the base model and collection to a JSON string

Question

I'm having trouble saving Backbone.Model or Backbone.Collection objects to local storage. The problem is that only attributes are saved when saved, and I don't want this. I actually use base-localstorage, which is represented in their TODO sample.

This is their save function.

save: function() { localStorage.setItem(this.name, JSON.stringify(this.data)); } 

When I look at what JSON.stringify (this.data) returns, I see that only models or collection attributes receive sets. Is there a way to indicate that I want to save all the state of the model and collection, and not just attributes?

Flip Model.toJSON or Collection.toJSON to return the data you want to serialize.

By default, Model.toJSON simply returns attributes:

 toJSON : function() { return _.clone(this.attributes); } 

The toJSON collection uses the toJSON model:

 toJSON : function() { return this.map(function(model){ return model.toJSON(); }); }
