Django：如何在我的视图中逐个迭代一个对象？

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只是得到一个关于我必须阅读的内容的提示...

这是我的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 %}

提前谢谢Flotzen

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

这听起来像你将你的对象扔到Paginator（'per_page为1）然后你可以穿过它们。
