我目前使用Django 3.1.2和Python 3.7。我在创建下面的测验时遇到了问题。
这是我的代码：

def index(request):
return render(request, 'apquiz/index.html')
#print(request.POST)
def question(request):
template = loader.get_template('apquiz/hi.html')
#questions = ["1. What is Dosie's position in PURPLE KISS?", "2. Yuki's position in PURPLE KISS, based on this excerpt is:","3. PURPLE KISS has how many members:","4. PURPLE KISS debuted on","5. Which of the following is PURPLE KISS's main vocalist?"]
#answers = [{'a. main rapper, main dancer, vocalist':0,'b. lead dancer, lead rapper':0, 'c. main dancer, vocalist':1,'d. main dancer, lead rapper':0},{'a. lead dancer, vocalist, rapper, visual':0,'b. lead rapper, lead dancer, vocalist, visual':0, 'main rapper, lead dancer, vocalist, visual':1, 'd. main vocalist, lead dancer, rapper, visual':0},{'a. 7':1,'b. 2':0,'c.9':0,'d.2':0}, {'a.

#questions = Question.objects.get()
#answers = Answer.objects.get()
question_set=Question.objects.all()
answer_set=Answer.objects.all()
context = {}
numberofquestions = len(question_set)
numberofanswers = len(answer_set)
numberofcorrectanswers = 0
for i in question_set:
for j in answers:
if i == j:
#context[i] = j #mke sure questions correspond to answrs
context['questions'] = question_set
if j.values == 1: #select the correct answer
numberofcorrectanswers += 1
percent = (numberofcorrectanswers/numberofquestions) * 100
if percent >= 25 and percent <= 50:
score = 2
elif percent > 50 and percent < 75:
score = 3
elif percent >= 75 and percent < 90:
score = 4
elif percent >= 90:
score = 5
else:
score = 1
response = "You are on track to get a" + str(score) + "on an exam like this."

这些是我使用最多的页面。如果有人能帮我修复这些文件，我将不胜感激。我正试图在不必使用管理文件进行编辑的情况下，用多选答案进行测试(这意味着它已经给出，你不能在管理网站中更改它们(，为了编辑这些问题，你必须自己编辑代码。到目前为止，我只看到一个回答按钮，它什么也不返回。我需要它来返回从1到5的分数(我正试图模仿Ap考试(。如果有人能帮我处理这个代码，或者让我知道任何错误，我将不胜感激。我的HTML技术不是很好，我特别需要在这方面的帮助，就像我不知道如何正确显示它们一样。
我稍微调整了一下您的代码。我希望这能给你一个起点。
