导致这个FatalErrorException的原因是什么？

I'm new in Laravel 5.1 Can you help me to solving this error because I've been working on this for whole day and I cannot solve it.

FatalErrorException in FileEntryController.php line 48: Call to undefined method App\Http\Requests\UploadFiles::save()

Here's my controller :

public function index()
{
    $entries = Fileentry::where('user_id',Auth::user()->id)->get();
    return view('fileentries.index', compact('entries'));
}


public function store(UploadFiles $filename)
{
      if($filename->file('filefield')) {
      $file = $filename->file('filefield');

      $entry = new UploadFiles();

      $extension = $file->getClientOriginalExtension();
      $entry->filename = $file->getClientOriginalName();

      $entry->mime = $file->getClientMimeType();
      $entry->original_filename = $file->getClientOriginalName();
      $entry->description = Request::input('description');
      $entry->user_id = Auth::user()->id;

      $entry->save();


      $file->move(Storage::disk('local')->put($file->getFilename().'.'.$extension,  File::get($file)));

      return redirect('upload');

       }
}

And here is my Request/UploadFiles.php

namespace App\Http\Requests;

use App\Http\Requests\Request;

class UploadFiles extends Request
{
/**
 * Determine if the user is authorized to make this request.
 *
 * @return bool
 */
public function authorize()
{
    return true;
}

/**
 * Get the validation rules that apply to the request.
 *
 * @return array
 */
public function rules()
{
    return [
        'filename' => 'mimes:pdf,doc,jpeg,png,docx',
        'description' => 'required',
    ];
}

Your code will not work as expected, and some parts of it should be removed. First in your store() method, you have already imported UploadedFiles instance. From your code, I see UploadedFiles is a Request class, so this is fine.

However, you should not make another UploadedFiles instance, within the store method, as this does not make sense.

You should however make a new Model called (File) for instance, and you code should be something like below.

public function store(UploadFiles $filename) { if($filename->file('filefield')) { $file = $filename->file('filefield');

  $entry = new Files();

  $extension = $file->getClientOriginalExtension();
  $entry->filename = $file->getClientOriginalName();

  $entry->mime = $file->getClientMimeType();
  $entry->original_filename = $file->getClientOriginalName();
  $entry->description = Request::input('description');
  $entry->user_id = Auth::user()->id;

  $entry->save();


  $file->move(Storage::disk('local')->put($file->getFilename().'.'.$extension,  File::get($file)));

  return redirect('upload');

   }

}
