Accessing parent scope from directive

Question

This is how I can access the exact scope value, otherwise it will be $scope.type of local scope.

I am accessing this from the template in NSPopover. NSPopover directive has scope: true.

It's also inside the Angular bootstrap module.

<label ng-class="{selected: $parent.$parent.$parent.type == current.type}" >
    <input type="radio" name="type" ng-value="current.type" ng-change="chooseOption()" ng-model="$parent.$parent.$parent.type"/>

Answer 1

Using $parent is an anti-pattern and sign of bad architecture. What if you code changes together with your parent chain - it will instantly break your code.

Also, have you thought about how you are going to test it?

To have a clean readable code, you want someone looking at it immediately see the meaning. What is the meaning of this object? -

ng-model = "$parent.$parent.$parent.type"

Would you not rather see

ng-model = "selectedItem"

or something more concrete like

ng-model = "myCar"

Naming something "current" makes me wonder what it is. From your code, I have no idea, so it forces me to spend time on looking around and getting clues, for what should be made clear right up front.
