Question

我正在尝试用Django编写一个Quiztool。我创建了一个列出所有调查的索引。单击一个可以进入详细视图。现在，列出所有问题和答案，提交按钮无效。我要求的是如何管理将只有一个问题，当我提交答案时，下一个问题将不会跳出细节视图。如果答案很简单，我也会很高兴能够得到我必须阅读的内容......

以下是我的views.py

中的一些代码

def detail(request, survey_id):
    #try:

    question = Survey.objects.get(pk=survey_id).question.all()

    question_dict = {
      'question': question,
    }
    return render(request, 'survey/detail.html', question_dict)

这是我的deatil.html

{% if question %}
    <form method="post">
    {% for x in question %}
    <fieldset style="width:10%;">
      <legend>{{x.question_text}}</legend>
      {% for y in x.answer.all %}
        <p style="display: flex;justify-content: space-between;">
        <label for="{{ y.answer_id }}">{{ y.answer_text }}</label>
        <input name="{{x.question_id}}" type="radio" value="{{y.answer_id}}" id="{{y.answer_id}}"/></p>
      {% endfor%}
    </fieldset>
    {% endfor %}
    <input type="button" value="Senden" onclick="var Sende=()=>{console.log('gesendet');}; Sende();">
    </form>
{% else %}
    <p>No questions are available.</p>
{% endif %}

Answer 1

我认为最直接的方法是在Django中保持代码相同，并使用Javascript来处理用户在浏览器上看到的内容。然后，完成后，您可以像传统的表格帖子一样提交答案。

Answer 2

这听起来就像你将对象扔进Paginator（'per_page为1）然后你可以穿过它们。
