laravel - How can I set value for extra field on Eloquent pivot table -

$recourse->pivot->field = 'value';

gives error: indirect modification of overloaded property

pivot available in context of relation:

// won't work $model = model::first(); $model->pivot; // null  // work $anothermodel = anothermodel::first(); $relatedmodel = $anothermodel->relation()->first(); $relatedmodel->pivot; // pivot object 

but trying use additional param in save method:

$product = product::find($item->id); $order->product()->save($product, ['price' => 12.34]); 

for existing relation:

$product = $order->product()->find($productid); $product->pivot->price = 12.34; $product->pivot->save();  // or $order->product()->updateexistingpivot($productid, ['price'=>12.34]); 

and suggest use products kind of relation in order make easier read.
