I have collection that I need to order like this:
Here is my relationship function:
public function adMegaPremiumAdObjects()
{
return $this->hasMany(MegaPremiumAdObject::class, 'ad_id', 'id');
}
And with this I can only order my collection with fields inside that table:
public function index()
{
$collection = AdObject::orderBy('some_field', 'DESC')->get();
}
So I need to order this collection by my relationshipadMegaPremiumAdObjects
- if some Model have that relationship it needs to show first in a list.
If I try withwhereHas
it only shows me collection with that relationship and that doesn't help me.
How can I do that?
You can usewithCount()
to add a relation count column, which you can order by:
$collection = AdObject::withCount('adMegaPremiumAdObjects')->orderBy('adMegaPremiumAdObjects_count', 'DESC')->get();
From Laravel docs:
If you want to count the number of results from a relationship without actually loading them you may use the withCount method, which will place a {relation}_count column on your resulting models.
