Laravel error: Creating default object from empty value

Question

I'm trying to update a record in the database . I'm trying to update an already registered product, then I do the research and then create several objects to save , the problem that laravel returns an error mesage warning that I am trying to create an object with a null value , and I'm passing a value for he. Follows the code below

Model

public function edit()
{
    $idProduct = Input::get('pid');

    $produto = ProductModel::where('id', $idProduct)->first();

    $nome = Input::get('eNome');
    $descricao = Input::get('eDescricao');
    $userID = Auth::user()->id;

    $produto->nome = $nome;
    $produto->descricao = $descricao;
    $produto->users_id = $userID;

    if (Input::hasFile('eFoto'))
    {
        $file = Input::file('eFoto');

        $fileNameUniq = uniqid();
        $destinationPath = public_path().'assets/admin/gallery/';


        $extension = pathinfo($file->getClientOriginalName(), PATHINFO_EXTENSION);

        $fileName = uniqid();
        if(move_uploaded_file($file, 'assets/admin/gallery/'.$fileName.'.'.$extension)){
            $produto->foto = $fileName.'.'.$extension;
        }

    }

    $produto->save();

    return Redirect::back()->with(['message' => 'Produto alterado com sucesso!']);
}

use find instead of first.

$produto = ProductModel::find($idProduct);
$produto->name = $name;
$produto->save();

if you want to use update

 $produto = ProductModel::where('id', $idProduct)->update([your input content]);

This works, but I'd like to know how to use the features of objects as $ product- > name passing the value to the object

put your

{!! Form::close() !!}

under your

{!! Form::hidden('pid', $eProduct->id) !!}

so it will be posted as well.
