backbone.js - Backbone JS Handle Save Model? -

using backbone can fetch collection below , render backbone view each record:

person = backbone.model.extend({});  var personcollection = backbone.collection.extend({      model: person,     url: '/home/people/' }); 

when spin new person using backbone below, isn't supposed handle .save() functionality posting url defined in above collection?

var p = new person({ name: 'andrew', age: 24 }); p.save(); // uncaught error: 'url' property or function must specified // thought supposed use collection's url? // can around explicitly setting p.url doesn't seem right 

looks approach use current collection , create handles adding collection , saving it

this.people.create(p); 

the source below. create off collection, sets models collection this once save success adds model collection. passes model geturl, geturl looks @ url property on model, in turn passes collection geturl again... way don't have redefine url...

create : function(model, options) {   var coll = this;   options || (options = {});   if (!(model instanceof backbone.model)) {     model = new this.model(model, {collection: coll});   } else {     model.collection = coll;   }   var success = function(nextmodel, resp) {     coll.add(nextmodel);     if (options.success) options.success(nextmodel, resp);   };   return model.save(null, {success : success, error : options.error}); },
