How To Use groupBy in whereHas laravel

Have you tried passing a closure to groupBy method? Same as whereHas.

Yes but not worked I think the problem is morph!

Can you tell what you need that query to result to? Cause you can try something like

Meta::with('orders')->groupBy('value')->get();

Or even better

Meta::with('orders')->where('key', 'gmail')->get();

Just one thing, you should remove that screenshot from your initial post since it looks like real data.

i got this error there is any wat get metas from Order class and grouping them?

i have many orders that have same meta like gmail i want grouping them with meta and get orders that have same meta like gmail to use in backpack laravel crud

Just add that relationship and you are all set to go.

Should be something like

    public function orders(): MorphTo
    {
        return $this->morphTo();
    }

it works fine but i use this code:

Meta::with('metable')->where('key','gmail')->groupBy('value')->get();

but now how can i limit orders? for example just order that belongs to specific user or any where closure i try this but not worked

$this->data['emails'] = Meta::with(['metable' => function($query) {
            $query->where('user_id' , 2);
        }])->where('key','gmail')->groupBy('value')->get();

and nothing changed got all orders !

finaly i found the solution new feature of laravel 5.8 is a closure handled my problem whereHasMorph()

and this is working code:

$this->data['emails'] = Meta::whereHasMorph('metable' , Order::class , function($query) {
            $query->where('user_id' , 2);
})->where('key','gmail')->groupBy('value')->get();

Tnx Every One
