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？ [英] How to delete all records associated with an ember model without clearing local Storage?

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!

推荐答案

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 。
