Can I just work with regular data objects?

I have a simple model:

{
  name: "foo",
  description: "bar
}

But when I get it using this.get(“model”) I get this Ember object I have no idea how to work with.

How can I iterate over the fields? How can I just work with the dictionary?

You can work with Ember objects as with plain object. Use for … in, or Ember.keys() to enumerate fields.
