How to convert a Django QuerySet to a list

Question

I have the following:

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

then later:

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)

I get an error:

'QuerySet' object has no attribute 'remove'

I've tried all sorts to convert the QuerySet to a standard set or list. Nothing works.

How can I remove an item from the QuerySet so it doesn't delete it from the database, and doesn't return a new QuerySet (since it's in a loop that won't work)?

Answer 1

Why not just call list() on the Queryset?

answers_list = list(answers)

This will also evaluate the QuerySet/run the query. You can then remove/add from that list.
