如何删除与余烬模型相关联的所有记录，而不清除本地存储？

问题描述：

我已经扩展了此 stackoverflow答案有一个程序，一次删除所有的记录。但是，删除仅在批处理中发生，并且不会一次删除所有内容。

I have extended the program given in this stackoverflow answer to have a program that deletes all the records all at once. However, the deletion happens only in batches and does not delete everything all at once.

这是我在这个 JSBin 。

deleteAllOrg: function(){
  this.get('store').findAll('org').then(function(record){
    record.forEach(function(rec) {
        console.log("Deleting ", rec.get('id'));
        rec.deleteRecord();
        rec.save();
    });
    record.save();
  });
}

任何想法如何修改程序，以便可以删除所有记录一旦？

Any idea how the program can be modified such that all records can be deleted at once?

我也尝试过model.destroy（）和model.invoke（'deleteRecords'），但它们不起作用。

I have also tried model.destroy() and model.invoke('deleteRecords') but they don't work.

非常感谢任何帮助。感谢您的帮助！

Any help is greatly appreciated. Thanks for your help!

答

调用 deleteRecord（） forEach 将打破循环。您可以通过在 Ember.run.once 函数中包含删除代码来修复它，如下所示：

Calling deleteRecord() within forEach will break the loop. You can fix it by wrapping the delete code in an Ember.run.once function like this:

  this.get('store').findAll('org').then(function(record){
     record.content.forEach(function(rec) {
        Ember.run.once(this, function() {
           rec.deleteRecord();
           rec.save();
        });
     }, this);
  });

请参阅此jsBin 。
