在Jython 和 Django中，我试图用这个调用位于不同视图“normalize_name”中的视图函数param name="@#~½½¬}0.jpg"

我的电话是：

 documentName = str(normalize_name(name))

我无法理解的是，如果在调用的同一视图中具有该功能，为什么会起作用

调用的函数是：

def normalize_name(value):
  ext = value.split('.')[-1]
  value = join(value.split('.')[0:-1], '.')
  value = unicodedata.normalize('NFKD', value).encode('ascii', 'ignore')
  value = unicode(re.sub('[^\w\s-]', '', value).strip().lower())
  value = unicode(re.sub('[-\s]+', '-', value))

  return value + '.' + ext

我得到的错误：

提前谢谢
