我有以下内容:

answers = Answer.objects.filter(id__in=[answer.id for answer in answer_set.answers.all()])

然后:

for i in range(len(answers)):
    # iterate through all existing QuestionAnswer objects
    for existing_question_answer in existing_question_answers:
        # if an answer is already associated, remove it from the
        # list of answers to save
        if answers[i].id == existing_question_answer.answer.id:
            answers.remove(answers[i])           # doesn't work
            existing_question_answers.remove(existing_question_answer)

我收到一个错误:

'QuerySet' object has no attribute 'remove'

我已经尝试了各种将QuerySet转换为标准集或列表.什么都行不通.

如何从QuerySet中删除一个项目,以便它不会从数据库中删除它,并且不会返回一个新的QuerySet(因为它在一个不起作用的循环中)？
