findAll（）中的deleteRecord和findQuery（） [英] deleteRecord in findAll() vs findQuery()

问题描述

我刚刚遇到以下问题：在ArrayController中的$ code>内容中调用 deleteRecord（）在 findQuery（< model name> {}）的路线中设置，该模型未从 ArrayController ，即使 deleteRecord 成功（并且我调用保存来持久化该操作）。但是，当我将其切换到 findAll（）时，一切都按预期运行。任何想法可能是什么？

I just had the following problem: When calling deleteRecord() on a model in an ArrayController, whose content was set in the route with findQuery(<model name>, {}), the model was not removed from the ArrayController, even though deleteRecord was successful (and I called save to persist the action). However, when I switched it to findAll(), everything worked as expected. Any ideas why that might be?

我正在使用Ember 1.4.0-beta.1 + canary.4ffecd62和Ember Data 1.0.0-beta.4 + canary。 7af6fcb0。

推荐答案

find（'type'，{}） findQuery（'type'，{}）创建一个RecordArray。 findAll（'type'） / find（'type'）实际返回一个现有的RecordArray，它具有所有当前的在商店记录。

find('type', {})/findQuery('type', {}) creates a RecordArray. findAll('type')/find('type') actually returns a live RecordArray which has all of the current records in the store.

为了更全面地了解这一点，商店里还有另外两种方法 all / 返回Live RecordArrays，但是它们不会调用服务器进行记录。您可以将 findAll（'type'） / find（'type'）作为调用服务器的方法然后调用全部方法。

To more fully understand this there are two other methods on the store all/filter which return Live RecordArrays, but they make no call to the server for records. You can think of findAll('type')/find('type') as a method of calling the server then calling the all method.

如果您希望可以根据 findQuery 来欺骗并获得类似的效果。

If you wanted you could create a filter based off the results of your findQuery to cheat and get a similar effect.

  model: function() {
    return this.get('store').find('color', {dummy:'data'});
  },
  setupController:function(controller, model){
    var filter = this.store.filter('color', function(color){
      return model.contains(color);
    }); 

    this._super(controller, filter);
  },
