Query Classes

I'm sure I've heard JW mention the idea in one of his videos (or I might have dreamed it). But the thought of distilling repositories down and SRP occurred to me today while I was mucking about with a toy project.

I'd be interested in people's opinions of single query classes and the ups and downs of using them.

Something like this ...

class PropertyRatesInRange
{
    public static function get(int $propertyId, DateRange $range) : Collection
    {
        $property = Property::with('rates')->find($propertyId);

        return $property->rates->filter(function($rates) use($range) {
                    return $rates->dates->overlaps($range);
            });
    }
}
