我试图查询一个对象集，并使用对象的数量来执行一个for循环，该循环将呈现每个对象的参数。我使用一个2D数组来存储参数，这样它们就可以根据它们的对象来呈现。我想不只是一个解决方案，但在一般情况下，这样做的更好的方法。我刚接触django
这是来自views.py的代码

def flashcard(response):
    form = Flashcard_verif(response.POST)

    if response.method == "POST" and form.is_valid():
          
        head = form.cleaned_data["header"]
        ques = form.cleaned_data["question"]
        ans = form.cleaned_data["answer"]
            
        flashcard_data = Flashcard(header=head, question=ques, answer=ans)

        # this is where the error is occuring
        flashcard_obj = Flashcard(header=head, question=ques, answer=ans).objects.all()

        rawHeader, rawQuestion, rawAnswer = Flashcard(header=head, question=ques, answer=ans).flash_format()
        
        flashcard_data.save()

        if len(flashcard_lib) > 1:
            for i in range(0, len(flashcard_lib), 1):
                flashcard_lib.append([rawHeader, rawQuestion, rawAnswer])
            
            print(flashcard_lib)
        
            return render(response, "main/Flashcard.html", {
            "form":form,
            "Flashcard_lib":flashcard_lib,
            "flashcard":flashcard_obj})
        else:
            flashcard_lib.append([rawHeader, rawQuestion, rawAnswer])
            print(flashcard_lib)
            
            return render(response, "main/Flashcard.html", {
            "form":form,
            "header":rawHeader, 
            "question":rawQuestion, 
            "answer":rawAnswer
            })
        

    
    else:
        form = Flashcard_verif()
    
    return render(response, "main/Flashcard.html", {
        "form":form})

字符串
这是我使用2d数组的模板：

<div class="flashcard-view" id="flash" style="visibility: hidden">
    {% if Flashcard_lib|length >= 2 %}
        {% for i in flashcard_obj %}
            <div class="flashcard">
            {{ i.0 }}
            {{ i.1 }}
            {{ i.2 }}
            </div>
        {% endfor %}
    {% else %}
        <div class="flashcard">
        {{ header }}
        {{ question }}
        {{ answer }}
        </div>
    {% endif %}
</div>

型
当我运行服务器时，我注意到if语句执行了，但for循环没有执行。这是一个2合1的问题，我如何让它遍历列表。
