Laravel withCount() subquery

Question

How would I run a subquery on withCount()?

I have a query I want to run for multiple counts, each with their own subqueries.

Here is an example of something that I'm looking for:

$date_from = Carbon::parse('1/1/2018');
$date_to = Carbon::parse('1/2/2018');

$models = Model::query()
    ->withCount('relation1', function (Builder $query) use ($date_from, $date_to) {
        $query->whereBetween('relation1.date1', [$date_from, $date_to])
              ->where('value1', true);
    })
    ->withCount('relation2', function (Builder $query) use ($date_from, $date_to) {
        $query->whereBetween('relation2.date2', [$date_from, $date_to])
              ->where('value2', false);
    })
    ->withCount('relation3', function (Builder $query) use ($date_from, $date_to) {
        $query->whereBetween('relation3.date3', [$date_from, $date_to]);
    });

How do I do this so it will correctly grab the model counts based on the subquery per relation?

Can you include the raw MySQL you intend to run, and maybe add some sample data? — Tim Biegeleisen

I think you need to pass the sub-queries as associative array values:

https://laravel.com/docs/5.7/eloquent-relationships#counting-related-models

E.g.

$date_from = Carbon::parse('1/1/2018');
$date_to = Carbon::parse('1/2/2018');

$models = Model::withCount([
        'relation1' => function (Builder $query) use ($date_from, $date_to) {
            $query->whereBetween('relation1.date1', [$date_from, $date_to])
                  ->where('value1', true);
        }, 
        'relation2' => function (Builder $query) use ($date_from, $date_to) {
            $query->whereBetween('relation2.date2', [$date_from, $date_to])
                  ->where('value2', false);
        },
        'relation3' => function (Builder $query) use ($date_from, $date_to) {
            $query->whereBetween('relation3.date3', [$date_from, $date_to]);
        }
    ])->get();
