Laravel 5.2 |无法将文件上传到数据库

Question

我想在注册到名为“fotodosen”的列时上传个人资料图片。我已经尝试了这个但仍然无效。

这是我在DosenController中的方法：

public function store(CreateDosenRequest $request)
{
    $user = User::create([
        'name' => $request->input('name'),
        'username' => $request->input('username'),
        'email' => $request->input('email'),
        'password' => $request->input('password'),
        'admin' => $request->input('admin'),
     ]);

      $dosen = Dosen::create([
        'iddosen' => $request->input('iddosen'),
        'nipy' => $request->input('nipy'),
        'namadosen' => $user->name,
        'user_id' => $user->id,
        'alamatdosen' => $request->input('alamatdosen'),
        'notelpdosen' => $request->input('notelpdosen'),
        'tempatlahirdosen' => $request->input('tempatlahirdosen'),
        'tanggallahirdosen' => $request->input('tanggallahirdosen'),
        'agamadosen' => $request->input('agamadosen'),

    ]);

    return redirect('admin/dosen')->with('message', 'Data berhasil ditambahkan!');    

}

我已经尝试过了：

public function store(CreateDosenRequest $request)
{
    $user = User::create([
        'name' => $request->input('name'),
        'username' => $request->input('username'),
        'email' => $request->input('email'),
        'password' => $request->input('password'),
        'admin' => $request->input('admin'),
     ]);

      $dosen = Dosen::create([
        'iddosen' => $request->input('iddosen'),
        'nipy' => $request->input('nipy'),
        'namadosen' => $user->name,
        'user_id' => $user->id,
        'alamatdosen' => $request->input('alamatdosen'),
        'notelpdosen' => $request->input('notelpdosen'),
        'tempatlahirdosen' => $request->input('tempatlahirdosen'),
        'tanggallahirdosen' => $request->input('tanggallahirdosen'),
        'agamadosen' => $request->input('agamadosen'),

    ]);

  if($request->hasFile('fotodosen')){
$file = Input::file('fotodosen');
$file = $file->move(public_path().'/uploads/',$file->getOriginalFileName());
$user->fotodosen = $file->getRealPath();
 }
 $user->save();
  return $user;

    return redirect('admin/dosen')->with('message', 'Data berhasil ditambahkan!');    

}

但它仍然无效。

这是我的表格：

{{ Form::open(array('url' => 'admin/dosen', 'files' => true, 'method' => 'post')) }}
                            {!! Form::file('fotodosen', null) !!}
                    <div class="form-group">
                        <div class="col-md-6 col-md-offset-4">
                            <button type="submit" class="btn btn-primary">
                                <i class="fa fa-btn fa-user"></i> Register
                            </button>
                             {!! Form::close() !!}

我错过了什么？
