Python Django页面未加载异常'；字节'；对象是不可调用的问题

我正在用Django下载文件。我已经在url.py和views.py中添加了路径，试图生成将加载文件和呈现页面的代码

def download(request):

    render(request, 'personal/home.html') # seems that it doesn't work

    filename = "C:/some_path/test_file.txt"
    wrapper = FileWrapper(open(filename))
    response = HttpResponse(wrapper, content_type='text/plain')
    response['Content-Disposition'] = 'attachment; filename=%s' % os.path.basename(filename)
    response['Content-Length'] = os.path.getsize(filename)
    return response

结果我得到：

异常类型：TypeError

异常值：“字节”对象不可调用

有人能帮忙吗？

删除此行：

render(request, 'personal/home.html')

谢谢，这很有帮助。
