如何在Django中显示选定的投票选项和总体结果

from django.db import models

class Question(models.Model):
    question_text = models.CharField(max_length=200)
    pub_date = models.DateTimeField('date published')

class Choice(models.Model):
    question = models.ForeignKey(Question, on_delete=models.CASCADE)
    choice_text = models.CharField(max_length=200)
    votes = models.IntegerField(default=0)

from django.shortcuts import render, get_object_or_404
from .models import Question

def detail(request, question_id):
    question = get_object_or_404(Question, pk=question_id)
    return render(request, 'polls/detail.html', {'question': question})

def results(request, question_id):
    question = get_object_or_404(Question, pk=question_id)
    return render(request, 'polls/results.html', {'question': question})

<!-- detail.html -->
<h1>{{ question.question_text }}</h1>
<form action="{% url 'polls:results' question.id %}" method="post">
    {% csrf_token %}
    {% for choice in question.choice_set.all %}
        <input type="radio" name="choice" id="choice{{ forloop.counter }}" value="{{ choice.id }}">
        <label for="choice{{ forloop.counter }}">{{ choice.choice_text }}</label><br>
    {% endfor %}
    <input type="submit" value="Vote">
</form>

<!-- results.html -->
<h1>{{ question.question_text }}</h1>
<ul>
    {% for choice in question.choice_set.all %}
        <li>{{ choice.choice_text }} - {{ choice.votes }} vote{{ choice.votes|pluralize }}</li>
    {% endfor %}
</ul>
