Djnago 表单在编辑记录时出现错误

Question

我在根据 CHatquestion ID 编辑记录时遇到问题，如果选项为空，那么我需要根据相同的 chatquestion id 添加记录，如果选项中存在 chatqustion id 它将起作用， 我正在尝试多种方法来解决这个问题，但仍然找不到解决方案。

Models.py # thease 都是 3 个模型

        return self.type

    question = RichTextField(null=True, blank=True)
    problem_id = models.ForeignKey(
        Problem,
        models.CASCADE,
        verbose_name='Problem',
    )

    def __str__(self):
        return self.question
    is_first_question = models.BooleanField(default=False)

class Option(models.Model):
    option_type = models.CharField(max_length=250, null=True, blank=True)
    question_id = models.ForeignKey(
