Question

我希望投票按钮能够正常工作，当用户单击该按钮时，它应该会自己增加投票数。

views.py

    from django.shortcuts import render, get_object_or_404
    from django.http import HttpResponse
    from . models import Question, Choice
    from django.urls import reverse

    # Create your views here.

    def base(request):
        return render(request, 'base.html')

    def home(request):
        return render(request, 'home.html')

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

urls.py

    from django.urls import path
    from . import views

    urlpatterns = [
        path('', views.base, name='base'),
        path('home', views.home, name='home'),
        path('quest', views.quest, name='quest'),
    ]

                </div>
            {% endfor %}
        </ul>
    {% else %}
        <p>No Polls Available!!..</p>
    {% endif %}
    {% endblock %}

models.py

    from django.db import models

    # Create your models here.

    class Question(models.Model):
        title = models.CharField(max_length=100)
        image1 = models.ImageField(upload_to='pics')
        image2 = models.ImageField(upload_to='pics')
        pub_date = models.DateTimeField()

        def __str__(self):
            return self.title

    class Choice(models.Model):
        question = models.ForeignKey(Question, on_delete=models.CASCADE)
        vote1 = models.IntegerField(default=0)
        vote2 = models.IntegerField(default=0)

当用户单击投票时，我期望输出，它将使投票的值增加1，即，+ 1，但我不知道该怎么做。

我想让投票按钮具有适当的功能，但是我无法做到这一点
