如何通过其ID删除Ember Data记录 [英] How to delete Ember Data record by its ID

问题描述

解决方案

注意：如果使用Ember Data，我想知道如何删除记录。在调用 rec.deleteRecord（）之后，您还需要调用 rec.save（）来提交删除。

  this.get（'store'）。find（'model'，the_id_of_the_record）.then（function（rec） 
 rec.deleteRecord（）; 
 rec.save（）; 
}）; 
  

您可以通过在上述JSBin中添加记录（ http://jsbin.com/iwiruw/458/edit ），删除它，然后重新加载页面。在页面重新加载后（或者单击使用JS运行按钮），您将看到该记录复活。这里有一个添加了 rec.save（）的jsbin，您可以看到这些记录不会恢复生效。

With Ember Data, I would like to know how to delete a record given that I know its id.

解决方案

Note that after calling rec.deleteRecord() you also need to call rec.save() to "commit" the deletion.

this.get('store').find('model', the_id_of_the_record).then(function(rec){
  rec.deleteRecord();
  rec.save();
});

You can see that this is necessary by adding a record in the JSBin above (http://jsbin.com/iwiruw/458/edit), deleting it, and then reloading the page. You'll see that the record is "resurrected" after the page reloads (or if you click the "Run with JS" button). Here's a jsbin with rec.save() added, where you can see that the records do not come back to life.
