backbone-relational

问题 I really can't wrap my head around this one. For some reason, (and I suspect it has something to do with asynchronous requests) my model attribute is not being converted properly using the toJSON() function. FWIW, I'm attempting to do lazy loading with django-relational fetchRelated(). Here's where I made the fetchRelated() request and create a new view. $.when(usermodel.fetchRelated("movies")).then(function(){ var newview = new UserMovieList({model: usermodel}); newview.render(); }); And

问题 I am new to Backbone-relational, I am not sure what is the right way to use HasMany. I have a Parent model which have many children (by "many" I mean thousands of children). In order to avoid performance issue, I query children by their foreign key: /child/?parent=1 , instead of create a huge list of child_ids in Parent . But seems this is not the way Backbone-relational work. So I am wondering what is the right way to handle this. 1, Change my json api to include list of child id in parent,

问题 I'm trying to create a three cascading dropdown lists. First one constains projects, second contains tasks for selected project and the last one sites for selected task. I want to use the Backbone-Relational plugin, but have hard time to create the proper relations. That's my first time with this plugin.

问题 Backbone Relational is not an AMD compliant library, so I've gone ahead and found the use plugin to ensure underscore and backbone are both loaded as dependencies. Here is my config file require.config({ baseUrl: '../global/js', paths: { use: 'libs/utilities/use', jquery: 'libs/jquery/jquery-min', underscore: 'libs/underscore/underscore-min', backbone: 'libs/backbone/backbone-optamd3-min', text: 'libs/require/text', relational: 'libs/backbone/backbone-relational' }, use: { "relational": {
