Angular ng-repeat orderBy multiple fields as one field

Question

My question is not the same as orderBy multiple fields in Angular.

My array has objects where some have

{
  estimatedStartDate : "..."
}

and some have :

{
  actualStartDate : "..."
}

So is there a way to orderBy considering both fields.

orderBy:['estimatedStartDate','actualStartDate'] 

^ This doesn't work.

Here is a fiddle: http://jsfiddle.net/g201tudg/1/

So pretend like both of these fields are the same and then sort ?

Answer 1

Add a function like this to your controller:

$scope.sortByEitherDate = function(row) {
    if (row.actualStartDate) {
        return row.actualStartDate;
    }
    return row.estimatedStartDate;
}

Then order by it with orderBy:sortByEitherDate
