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!

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.

    Nowadays you can call `this.get('store').findAll('org').invoke('destroyRecord')` to delete them all. – Jacob van Lingen Nov 03 '14 at 15:22

    @Jacob, That actually doesn't work. Invoke uses the same forEach function. – NicholasJohn16 Mar 18 '15 at 06:44

    @NicholasJohn16: You are right, you need to add `coalesceFindRequests: true` to the RESTAdapter to let it work. See: http://emberjs.com/blog/2014/08/18/ember-data-1-0-beta-9-released.html#toc_coalescing-find-requests – Jacob van Lingen Apr 08 '15 at 09:36
  • @JacobvanLingen `this.get('store').findAll('org').invoke('destroyRecord')` send a GET request to /orgs instead of DELETE – Anuj Kulkarni Jan 12 '16 at 21:16
