angularjs - Firebase security rule for array of messages

Question

I am trying to display a list of messages based on the recipient but for now, let's keep it simple. I am just trying to display a list of messages.

My rule looks like this

{
"rules": {
  "communications" : {
    "$communication":{
      ".read" : true,
      ".write": true
    }
  }
}

For some reason though, my application does not want to read it

fireRef = new Firebase(url);
fireRef.auth(MY_TOKEN);
commsRef = fireRef.child('communications')
$scope.communications = $firebase(commsRef)

It only works if I have a rule looking like

{
"rules": {
  "communications" : {
    ".read" : true,
    ".write": true
  }
}

But that will cause problem as I would like to add condition on the children node of my communication. Something like:

{
"rules": {
  "communications" : {
    ".read" : true, ### I would like to get rid of this line as well and have the child handling it
    ".write": true,

    "$communication":{
      ".read" : "data.child('to').val() == auth.uid"
    }
  }
}

I am assuming that is because I have a $firebase on the communications and it needs some read or write rules but how do I get the event when a new message is added otherwise

Thanks
