在PUT之前从对象中删除Restangular特定数据

时间：2014-07-23 09:13:13

标签： angularjs tastypie restangular

我在使用ngTagsInput与我的Django-Tastypie后端而不是$resource对话的Angular webapp上使用Restangular。对于自动完成，我将列表加载为Restangular.all('technology').getList({'slug__startswith':q});，这会为我的模型添加一个元素。然后，我可以在我的模型上执行PUT来保存它。

问题是，我的模型中的元素是纯粹的非Restangulariezed对象（因为它们是由Restangular.one获取的），当我以这种方式添加标记时，添加的元素是Restangularized（使用Restangular特定的方法）和属性）。当然，这会引发500错误。任何出路？

我知道我可以添加一个自定义响应提取器，就像这样。

RestangularProvider.setResponseExtractor(function(response) {
  var newResponse = response;
  if (angular.isArray(response)) {
    angular.forEach(newResponse, function(value, key) {
      newResponse[key].originalElement = angular.copy(value);
    });
  } else {
    newResponse.originalElement = angular.copy(response);
  }

  return newResponse;
});

但我正在寻找最干净的方法。

编辑：更多数据。

technology对象应如何显示：

{0: Object
category: "LNG"
created: "2014-07-17T18:17:19.350286"
description: ""
id: 5
modified: "2014-07-24T13:15:16.618184"
name: "Python"
resource_uri: "/api/v1/technology/python"
slug: "python"
verified: true}

在进行Restangularized之后的样子：

我在github上看到了这个方法来清理Restangularized数据中的对象并且它正在完成这项工作。

data = Restangular.stripRestangular(RestangularObjectToClean)

mgonto说他打算在这个问题#667

上添加一个clean（）方法
