Python Django-使用inline保存和更新表单集

我有一个TestingQuestion和TestingQuestion选项类。 创建测试问题时，我也使用StackedLine创建测试问题选项。 目前，创建新的TestingQuestion以及TestingQuestionOptions可以正常工作。 我遇到的问题是，当我想保存我已经创建的测试问题时。ie尝试编辑并保存更改。 我在这一行出现“列表索引超出范围”错误

 "question = saved_options[0].question"

它位于“TestingQuestionFormSet”类下的“保存现有对象”方法中

返回None，我不知道为什么，因为我希望它返回TestingQuestionOption。 任何帮助都将不胜感激。谢谢
