Cannot upload file in a database

Hello. I had a problem with storing the uploaded file on a database. I didn't store it in the database.

Controller

public function update(Request $request, $id)
    {
        $fileModel  = Attendance::where('attendance_id', $id)->first();

        if($request->file()) {
            $fileName = $request->file->getClientOriginalName();
            $filePath = $request->file('file')->storeAs('uploads', $fileName, 'public');

            $fileModel->name = $request->file->getClientOriginalName();
            $fileModel->file_path = '/storage/' . $filePath;
            $fileModel->attendance_id = $request->input('attendance_id');
            $fileModel->attendance_name = $request->input('name');
            $fileModel->save();

            return back()
            ->with('success','File has been uploaded.')
            ->with('file', $fileName);
        }
    }
