Mogo db object used in angular

angular
1

I am doing this:

vm.helpers({
shot: function() {
return Shots.findOne({ _id: $stateParams.shotId });
}
})

vm.subscribe(‘shots’);

vm.videoContent = vm.shot.version[vm.shot.version.length-1].videourl
//this is undefined because the shot object is not ready yet. is there a callback or a promise i can use?

vm.autorun() is what you need I think.
