ng-hide if value is empty

[Heydon Pickering]

Just a quick one:

How do I use ng-hide to hide an element if a value in my model is empty? I tried

<a href="#" ng-hide="modelValue == ''">Hidden if empty</a>

Sorry if this is a really simple one :-)

I use for instance "$scope.user === NULL" when I need to hide parts of the user experience that's only for logged in users.

How would you show/hide an elements based on a nested property in the model?  e.g. $scope.person.personId
