How to load data with possibly different types into the controller?

Question

Angular

Angular used to support the ability to load data directly from a Promise. For logical reasons (not obvious assignment), this feature was removed.
Now you need to write like this

getdata(1).then(function(data)
{
    $scope.data = data;
});

But, now it is extremely important for me not to exit the stream sometimes, so getdata can return an array directly without a Promise, or it can return a Promise.
To do this, I use a helper function
Simplified like this:

Интерфейс
loadData($scope, name, getter, params);

//и вызов
loadData($scope, 'data',getdata, [1]);

It checks whether the function has returned a Promise or data and accordingly assigns the value to $scope immediately or after then.
Attention, question! Who has any ideas in this direction, maybe there are more beautiful solutions?

Answer 1

Why is this option bad?

Answer 2

$q.when

$q.when(loadData()).then(function (result) {
    $scope.data = result;
});

But just keep in mind that the callbacks in then are not executed synchronously, but as it happens in the event loop. That is, you may have a couple of milliseconds to pass between the call to loadData and the callback in then. If this is critical for you, you can use your solution.

Answer 3

So you contradict yourself.

But, now it is extremely important for me not to go out of the flow sometimes

and at the same time admit that a promise can return.
You probably have a misunderstanding somewhere. Please describe the situation in more detail.
