DS is not defined

I've followed the whole video and did everything that was done in the video. Nevertheless, if I preview the project I get a blanc screen and the error: Uncaught ReferenceError: DS is not defined. routes/posts.js:

Blogger.PostsRoute = Ember.Route.extend({
  model: function(){
    return this.store.find('post');
  }
});

models/post.js:

Blogger.Post = DS.Model.extend({
  title: DS.attr(),
  body: DS.attr()
});

models/comments.js:

Blogger.Comment = DS.Model.extend({
  text: DS.attr()
});

index.html:

Am I overlooking something?

Hello Sanne van Tongelen

The first error I see is about the ember-data.js file. I opened your ember-data.js file and it was missing some of the code. I replaced the code in your workspace and it seems to be working now. I'm not sure how the code disappeared from the ember-data.js file, but that was the issue.

Sanne van Tongelen are you working in Workspaces for this? If so can you take a Workspace snapshot and share it here in the forum?

Could you also provide me with the solution to this? I appear to be having the same problem as well. Here is a snapshot of my workspace:

Here is a link to the screenshot of my dev tools, this is where the error appears. Screenshot devtools

The workspace snapshot doesn't add any value, so I added a screenshot, with my index file and the folders opened. Screenshot workspaces

Hopefully this gives you enough information.

Hi Sanne van Tongelen. A Workspace snapshot would be the best way for us to track down the error -- we can fork your snapshot into a workspace, then test your code to see what is going wrong. The screenshots aren't that helpful in tracking down this error. Could you post a snapshot? Thanks
