example:
Model::sum('subarray.*.price');
this method is much simpler as to use as complex raw aggregations
for this function a $unwind directive will be pushed in pipeline before $group
change test for different scenarios

With this code it is possible to use aggregation functions (sum, count, max, min, avg, ...) on subdocument arrays (embedsMany). To use this functionality you have to pass
array.*.fieldto the corresponding aggregation function.Check out the code example in
testSubdocumentArrayAggregateinQueryBuilderTest.php.As you can see with this solution it is very simple to apply the aggregation functions instead of writing complex raw aggregations. In my scenario, the code is much simpler and cleaner.
I would be glad to get feedback if you are interested to this functionality, or if you have suggestions for improvements or alternatives.
