Django

Question

我有以下代码：

exercises = Exercise.objects.filter(teacher=request.user.id).values('id', 'question', 'ans1', 'ans2', 'ans3', 'correct', 'unit', 'resol', 'theme', 'img')

这很好用，但是“主题”是一个多对多字段，格式 returns { ..., theme: value } 而不是 { ..., theme: [value1, value2] }

我应该实施什么以获得所需的格式？

Answer 1

通过执行以下操作使其工作：

try:
    exercises = Exercise.objects.filter(teacher=request.user.id)
    ids = exercises.values_list('id', flat=True)

    reloaded_qs = Exercise.objects.all()
    reloaded_qs.query = pickle.loads(pickle.dumps(ids.query))
    exercise_serializer = ExerciseSerializer(exercises, many=True)

    if exercise_serializer.is_valid:
        for val, q in enumerate(reloaded_qs):
            exercise_serializer.data[val].update(q)

except BaseException as e:
    return JsonResponse({ 'v': False, 'm': str(e) }, safe=False)
 
return JsonResponse(exercise_serializer.data, safe=False)
