Python 如何保存用户的数据？

我有一个模型： models.py

url.py

demo.html

---

我想在按下按钮后，用户的点增加一个。我真的想不出来。

试试这样的办法

def demo(request):
    if request.method == "POST":
        profile = UserProfile.objects.get(user=request.user)
        profile.points += 1
        profile.save()
        return render(request, 'app/demo.html', {"user":request.user,
                                                 "profile":profile)

我知道有人已经提供了解决方案，但如果还没有，我真的建议你阅读

urlpatterns = [
    url(r'^$', demo),
    url(r'^demo/$', demo),
]

<form action="" method="POST">
    <button type="submit">+</button>
</form>

def demo(request):
    if request.method == "POST":
    # I don't understand how I can get "points" from the model   "UserProfile"
    #to add 1 and  to save in the DB
    return render(request, 'app/demo.html')

def demo(request):
    if request.method == "POST":
        profile = UserProfile.objects.get(user=request.user)
        profile.points += 1
        profile.save()
        return render(request, 'app/demo.html', {"user":request.user,
                                                 "profile":profile)
