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

Question

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.

Here is a snippet of the function I am using in this 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();
  });
}

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

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

Any help is greatly appreciated. Thanks for your help!

Answer 1

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);
  });

See this jsBin.
