angularjs - 如何从角度资源 $save() 读取响应并保留原始数据

Question

我是 Angular 的新手。我确定我在这里遗漏了一些基本的东西。

我有一个对象，我将其发布到服务器以创建它。服务器返回对象 ID，我需要读取和更新客户端中的对象。

服务器只会返回对象 ID，但是，在客户端，我有其他数据在我执行回调时无法使用（我无权访问原始数据）。

添加了以下 jsfiddle 代码作为参考：

//Get Angular Project module
var app = angular.module("app", ['ngResource']);

//create Project factory
app.factory('Project', function ($resource) {
    return $resource('http://cmsanalyticsdev.pearson.com\\:8081/api/projects/:projectid',
            {projectid:'@id'},
            {update: {method:'PUT', isArray:false}}    
    );

});


//Controller for testing
app.controller('ApplicationController', function ($scope, Project) {

//Project object
var project = new Project({"name":"New Project Test","thumbnail":"","statusid":"521d5b730f3c31e0c3b1e764","projecttypeid":"521f585c092a5b550202e536","teamid":"521f585a092a5b550202e521","authors":[{"firstname":"Dilip","lastname":"Kumar"}],"projectspecificmetadata":{"isbn13":"345345","guid":"asfas"},"modifiedby":"521f585a092a5b550202e525"}
);
//Create new project
project.$save(project, function (projectResponse) {
                        project.projectId = projectResponse._id;
                        alert(project.name);
                    });

});

我想你想要这样的东西：

//Controller for testing
app.controller('ApplicationController', function ($scope, Project) {

        //Project object
        var projectData = {"name":"New Project Test","thumbnail":"","statusid":"521d5b730f3c31e0c3b1e764","projecttypeid":"521f585c092a5b550202e536","teamid":"521f585a092a5b550202e521","authors":[{"firstname":"Dilip","lastname":"Kumar"}],"projectspecificmetadata":{"isbn13":"345345","guid":"asfas"},"modifiedby":"521f585a092a5b550202e525"};
        var project = new Project(projectData);

        //Create new project
        project.$save(project, function (projectResponse) {
                                projectData.projectId = projectResponse.id;
                                console.log("ProjectData: %j", projectData);
                            });

    });

以下是 $update 的类似方法。

 //keep original data to pass into callback
 var originalProjectObject = angular.copy(project);
 //Call server to update the project data
 project.$update({ projectid: project._id }, function (projectResponse) 
 {
   originalProjectObject._id = projectResponse._id;
   //update scope
   scope.project = originalProjectObject;                        
 },originalProjectObject);
