public function update(Request $request, $id){


       $idproduto=$request->get('idproduto');
      $atendecompra=$request->get('atendecompra'); 
       $cont = 0;

Model

class RequisicaoDet extends Model
{
   protected $table         ='requisicaodet';
   protected $primaryKey    ='idrequisicaodet';
   public $timestamps       =false;
   protected$fillable       =[
   'idrequisicao',
   'idproduto',
   'qnt',
   'detalhe',
   'idcentrocusto',
   'atendecompra'
    ];
   protected $guarded       =[];
}

Answer 1

To update the Model instance in Laravel, you can use the following syntax:

RequisicaoDet::find($id)->update([
  'atendecompra' => $request->get('atendecompra')
]);

It wasn’t very clear why you did that while there with the idproduto, but with the above command will solve your question, which is how to update the atendecompra for the specific id.

If there is any doubt, say I will improve the answer.
