Merge 'with' and 'whereHas' in Laravel 5

Question

I have this code in Laravel 5, using Eloquent, which is working perfectly:

$filterTask = function($query) use ($id) {
    $query->where(\'taskid\', $id);
         


        

Answer 1

The 'macroable' way (Laravel 5.4+)

Add this inside a service provider's boot() method.

\Illuminate\Database\Eloquent\Builder\Eloquent::macro('withAndWhereHas', function($relation, $constraint){
    return $this->whereHas($relation, $constraint)->with([$relation => $constraint]);
});
