What is the following line doing: [discourse/app/assets/javascripts/discourse/models/store.js.es6  
 ](https://github.com/discourse/discourse/blob/master/app/assets/javascripts/discourse/models/store.js.es6#L98)?

```js
return this._hydrate(type, result[Ember.String.underscore(type)], result);

```

In particular, why is the second argument of the `_hydrate()` method not the `result` object? Usually, the second argument for this method is the record object that is saved to/retrieved from the store.

Here, when I’m trying to find a record by ID, I will always run into this line:

```js
if (!obj) {
  throw new Error("Can't hydrate " + type + " of `null`");
}

```

That’s because `_hydrate()` will be called with `result[Ember.String.underscore(type)]`. Since my record doesn’t have a property named like the `type`, that’s always `undefined`.

Is that a bug?
