Error Call to a Member Function store() on string - image upload error

Question

I’m trying to make a upload of images using the public function create, but when I try to send the form to register the error appears:

Error Call to a Member Function store() on string

Does anyone know how I can solve?

PUBLIC FUNCTION CREATE:

 public function create(Request $request)
    {
        
        $user = Auth::user()->id;
        $data = $request->all();

        /*if($request->image->isValid()){*/

           $image = $request->image->store('livros');
           $data['image'] = $image;
     /*   }*/
        Livro::create([
            'users_id' => $user,
            'namel' => $request['namel'],
            'autor' => $request['autor'],
            'editora' => $request['editora'],
            'categoria'=> $request['categoria'],
            'classificação'=>$request['classificação'] ,
            'descricao'=>$request['descricao'],
            'image'=>$request['image'],
        ]);
        return view('livros/cadastro');

        
    }

Answer 1

The create method of the controller is the view, that is, you do not create/change/delete the database in view, the Laravel uses by default the "store" method to create the data, IN CASE on the routes you have used the RESOURCE method. Ex.:

Route::resource('cadastro-livros', 'LivrosController');

Using "Resource", the Laravel creates the methods:

1. index() (GET - main view)
2. create() (GET - creation view)
3. store(Request $request) (POST - method to save data)
4. show($id) (GET - item details selected by ID)
5. Edit($id) (GET - edit view)
6. update(Request $request, $id) (PUT - data editing method)
7. delete($id) (DELETE - method for deletion of data by ID)

So the create method will not receive Request, it is a GET protocol view, IE, the request will be received by the store method, and so your code will be like this:

public function store(Request $request)
{
    
    $user = Auth::user()->id;
    $data = $request->all();

    /*if($request->image->isValid()){*/

       $image = $request->image->store('livros');
       $data['image'] = $image;
 /*   }*/
    Livro::create([
        'users_id' => $user,
        'namel' => $request['namel'],
        'autor' => $request['autor'],
        'editora' => $request['editora'],
        'categoria'=> $request['categoria'],
        'classificação'=>$request['classificação'] ,
        'descricao'=>$request['descricao'],
        'image'=>$request['image'],
    ]);
    return view('livros/cadastro');        
}
