Question

好吧，帮帮我，我快疯了！

我有 4 个问题，每个问题的单选按钮名称设置为问题 id，值设置为答案 id 以获取答案的 id 并使用它来获取用户提交的答案以检查它是否正确。< /p>

views.py

def sampleQuestions(request):
    if request.method == 'POST':
        user = request.user
        userInformation = UserInformation.objects.get(user=user)
        allAnswers = Answers.objects.all()
        allQuestions = Questions.objects.all()
        i = 0
        for q in Questions.objects.all():
            print(q.id) #returns 1
            answerID = request.POST.get(q.id) #returns None
            print(answerID)
            answer = Answers.objects.get(id=answerID)
            print(answer)

模板.html

{% for q in questions %}
            <table> 
                <tr>
                    <td> {{q.question}}</td>
                </tr>
                {% for a in answers %}
                {% if a.answerForQuestion == q%}
                <tr>     
                    <td> <input type="radio" name = "{{q.id}}" value="{{a.id}}"> {{a.answer}}</td> 
                    {{q.id}}
                </tr>
                {% endif %}
                {% endfor %}
                </fieldset>
            </table>
        {% endfor %}

Answer 1

request.POST id 一个 python 字典，key 作为字符串。所以在键查找中提供一个字符串。

answerID = request.POST.get(str(q.id)) #returns None

request.POST.get(variable) 在尝试通过 id 接收时返回 None
