Question

我有一个使用Django / Tastypie后端和Backbone / Marionette前端的Web应用程序。我想使用Tastypie的bulk operations通过我的API使用PATCH请求创建多个对象到列表端点。

我的理解是Backbone不支持这一点。将此添加到Backbone的最佳方法是什么？我假设我需要向Backbone的集合对象添加一个save方法并扩展Backbone同步方法。

   If instead, you'd only like the changed attributes to be sent to the server, call 
   model.save(attrs, {patch: true}). You'll get an HTTP PATCH request to the server
   with just the passed-in attributes.

Fiddle在骨干收集同步上发送补丁请求：

$(function() {

  Backbone.$ = $;

  var User = Backbone.Model.extend({
    urlRoot: "/testUrl",
    isNew : function () { return false; },
    defaults: {
        name: 'John Doe',
        age: 25
    }
  });
  var user1 = new User();
  var user2 = new User();
  var user3 = new User();
  var user4 = new User();
  var UserCollection = Backbone.Collection.extend({
    model: User,
    url: "/testUrl"
  });
  var userCollection = new UserCollection([ user1, user2, user3]);
  // update
  user1.set('name','Jane Doe');
  user4.set('name','Another User');

  // delete
  userCollection.remove(user2);

  // add
  userCollection.add(user4);

  userCollection.sync('patch', userCollection , { error: function () {                       
    console.log(userCollection); } });
  });

将PATCH方法添加到Backbone集合
