如何保存用户的数据？

Question

我有型号： models.py

class UserProfile(models.Model): 
    user = models.OneToOneField(User, related_name='userprofile') 
    points = models.IntegerField(default=0) 

urls.py

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

demo.html

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

views.py

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') 

我想按一下用户的按钮点增加一个。我真的无法弄清楚。

尝试是这样的

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)
