Good day everyone.

I know that I can use `@this` to access `itemController`’s property, e.g.:

```
foos: Em.computed.mapBy('@this', 'foo')

```

How can I access `itemController`’s property in the next example?

```
foos: function() {}.property('@this.foo') // doesn't work
foos: function() {}.property('@this.@each.foo') // doesn't work too

```

Thanks.

Assuming you’re working with an Array Controller, change the last line of your example code from:

```auto
foos: function() {}.property('@this.@each.foo')

```

to:

```auto
foos: function() {}.property('content.@each.foo')

```

You would be enumerating over the array controllers model’s here which he doesn’t want to do, he/she wants to enumerate over the item controllers.

```js
foos: function() {}.property('@each.foo')

```

Cool, thanks.

I’ve tried `@each.foo` on Ember `1.5`, but it didn’t work, that’s why I’ve created this topic.

Ah, good catch; totally missed that.
