Ordering by custom field is not working

[ivanflashacademy]

Hi everyone!

What steps will reproduce the problem?

I encountered a problem when I needed to order my collection list by custom column
For instance I add a custom column to my query with method select

$query->select(['customColumn' => ['$size' => '$items']])

// and then I need to order by this custom column
$query->addOrderBy(['customColumn' => SORT_DESC])

And nothing happens
PS I have already tried 1 and -1 instead of using SORT_ASC and SORT_DESC

What's expected?

I expect same behaviour when I use $project or $addField parameters in native query
Actually this works fine

$collecion->aggregate([
            [
                '$project' => [
                    'customColumn' => ['$size' => '$items'],
                ]
            ],
            [
                '$sort' => ['customColumn' => -1]
            ],
])

I would like you to add a couple of methods for $project

$query->projects([...])
$query->addProject([...])

Or add existing fields to $project

What do you get instead?

Nothing
