Bubbling events in nested Backbone (Marionette) Models / Collections

阅读更多关于 Bubbling events in nested Backbone (Marionette) Models / Collections

We have a large Marionette App, that uses Backbone.trackit to monitor unsaved changes in our Models. We now have some nested models, in fact we have a Model, with a Collection of Models, that contain a Collection of Models. trackit doesn't support the top level model being marked as 'dirty' when the child models change - due to backbone not bubbling these change events. I know we could manually monitor these change events, but Im looking for a generic solution. Has anyone had any experience of the following libs or any other solutions for this? backbone-deep-model Backbone Associations events

Saving jQuery UI Sortable's order to Backbone.js Collection

阅读更多关于 Saving jQuery UI Sortable's order to Backbone.js Collection

I have a Backbone.js collection that I would like to be able to sort using jQuery UI's Sortable. Nothing fancy, I just have a list that I would like to be able to sort. The problem is that I'm not sure how to get the current order of items after being sorted and communicate that to the collection. Sortable can serialize itself, but that won't give me the model data I need to give to the collection. Ideally, I'd like to be able to just get an array of the current order of the models in the collection and use the reset method for the collection, but I'm not sure how to get the current order.

In my application, I am trying to use Firebase to store the real time data based on backbone framework. The problem goes like this: I have a sub level model and collection, which are both general backbone model and collection. var Todo = Backbone.Model.extend({ defaults: { title: "New Todo", completed : true } }); var Todocollection = Backbone.Collection.extend({ model: Todo, initialize: function() { console.log("creating a todo collection..."); }, }); And then there is a high level model, which contains the sublevel collection as an attribute. var Daymodel = Backbone.Model.extend({ defaults :

Best practice for saving an entire collection?

阅读更多关于 Best practice for saving an entire collection?

问题 Say that I have a Collection and I've made changes to many of its Models. What's the best way to save all of the changes using a single HTTP request? 回答1: Usually REST backends handle single instance creation/update. You would need to change that to accept an array of objects. That said, on the client side, you would need to go directly to the Backbone.sync function Backbone.sync = function(method, model, options) In this case your model should be an array of model. The method should be
