如何在Laravel框架中使用Eloquent将文件插入数据库？

我正在尝试将图像插入我项目中的数据库，但未按预期工作，我不确定在哪里出错。我不断从警报模板中收到此错误消息。

该图像必须是图像。图片必须是以下类型的文件：jpeg，png，jpg，gif，svg。

表示上传的图片是Jpeg格式的图片。我需要帮助

public function register(Request $request){

    $this->validate($request, [
        'image' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048',
    ]);

    $newStudent = new Student;

     if($file = $request->hasFile('image')) {
        $file = $request->file('image') ;
        $fileName = $file->getClientOriginalName() ;
        $destinationPath = public_path().'/uploads/' ;
        $file->move($destinationPath,$fileName);
        $newStudent->image = '/public/uploads/'.$fileName ;
    }
        $newStudent -> StudentID = $request -> input('StudentID');
        $newStudent -> cLevel = $request -> input('cLevel');
        $newStudent -> surName = $request -> input('surName');
        $newStudent -> fName = $request -> input('fName');
        $newStudent -> fEmail = $request -> input('fEmail');
        $newStudent -> DoB = $request -> input('DoB');
        $newStudent -> pAddress = $request -> input('pAddress');


    $newStudent -> save();
   return response()->json(['status' => 'Image Uploaded Successfully']);
}
