Parent properties in MDV?

[Bradley Meck]

I have been playing with polymer for a couple of days now and was wondering:

I have a monster farming game with a <monster-picker> that is essentially a <fieldset> of <input type=radio>s, in order to handle single selection of monsters the names of the radio buttons need to be identical. Right now I am denormalizing down, but was wondering if there was a simple way to access parent properties that I was not aware of in MDV. For example:

Given:

```JS

{

  name: "buyable-monsters"

  monsters: [{name:"Billy",breed:"goat"}]

}

```

and

```html

<fieldset name={{name}}>

  <template repeat={{monsters}}>

    {{name}} - {{breed}}<input type=radio name={{../name}}> <!-- should match fieldset -->

  </template>

</fieldset>

```

Becomes:

```html

<fieldset name=buyable-monsters>

  Billy - goat <input type=radio name=Billy>

</fieldset>

```

Take a look at the custom syntax, it allows you to use {{path as name}} and then you can refer to it as {{name}} later on.

You can use the Named Scope syntax to accomplish this:

<template repeat="{{monster in monsters}}">

 {{monster.name}} -- {{monster.breed}}<input type-"radio" name="{{name}}" <!-- this name is the top level "name" -->

</template>
