如何使用django框架创建Quiz应用程序？

Question

我正在尝试做一个小测验应用程序，随机地问5 quetions.Before我在模型中使用了forein键。我通过一个django document.Now，我想在同一个page.while上呈现所有的等式和它的4个选项，在文档中，它创建了一个链接，在每个字符上只使用它的id呈现一个字符。现在，如果我在同一页上渲染，它就不会为每一张纸分开广播。参考链接：https://docs.djangoproject.com/en/3.0/intro/tutorial01/我的代码如下所示：

models.py

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

    def __str__(self):
        return self.question_text

    def was_published_recently(self):
        return self.pub_date >= timezone.now() - datetime.timedelta(days=1)


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

    def __str__(self):
        return self.choice_text

views.py

def index(request):
    latest_question_list = Question.objects.all()
    context = {'latest_question_list': latest_question_list}
    return render(request, 'index.html', context)

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

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


def vote(request, question_id):
    question = get_object_or_404(Question, pk=question_id)
    try:
        selected_choice = question.choice_set.get(pk=request.POST['choice'])
    except (KeyError, Choice.DoesNotExist):
        # Redisplay the question voting form.
        return render(request, 'detail.html', {
            'question': question,
            'error_message': "You didn't select a choice.",
        })
    else:
        selected_choice.votes += 1
        selected_choice.save()
        # Always return an HttpResponseRedirect after successfully dealing
        # with POST data. This prevents data from being posted twice if a
        # user hits the Back button.
        return HttpResponseRedirect(reverse('app1:results', args=(question.id,)))

index.html这里创建了链接

{% if latest_question_list %}
    <ul>
    {% for question in latest_question_list %}

        <li><a href="{% url 'app1:detail' question.id %}">{{ question.question_text }}</a></li>

    {% endfor %}

    </ul>
{% else %}
    <p>No polls are available.</p>
{% endif %}

detail.html在单击quetion之后，它出现在下面的页面中，其中显示了带有ans的符号格式。

<h1>{{ question.question_text }}</h1>
{% if error_message %}<p><strong>{{ error_message }}</strong></p>{% endif %}

<form action="{% url 'app1:vote' 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>

Answer 1

当您按submit时，将所有输入数据作为参数发送到post，因此，如果您将所有输入放在一种形式中，它将发送全部输入数据。您可以用一个名称来计算数据，您可以调用第一个输入1和第二个输入2等等，在服务器端，您应该检查所有的输入，如果答案确定，您也可以使用js发送您曾经去过的东西。
