python - 想保存每个用户django的数据

Question

我有用户配置文件模型

class UserProfile(models.Model):
    user = models.ForeignKey(User) 
    score = models.IntegerField(max_length = 50, blank = True,null = True)


    def __str__(self):

        return "%s's profile" % self.user

我的观点是

@login_required()
def score(request):
    if request.is_ajax():
        print request.method
        if request.method == 'GET':
            try:
                user1 = UserProfile.objects.get(user=request.user)
                print user1
                user1.score = request.GET.get('bjpFan')
                user1.save()
                print user1.score
                print "rahul"
                return HttpResponse("%s" % user1.score )

            except UserProfile.DoesNotExist:
                print "Gaurav"
                user1 = create_user()
            return HttpResponse("%s" % user1.score )

所以分数被存储到数据库中，但是当新用户使用这个应用程序时，他的对象没有被存储。如果用户是第一次使用此应用程序，则希望为他创建新对象。 我还创建了 userprofile 对象。

def create_user(username, email = None, password = None):   

    try:
        user = User.objects.get(username=username)
    except:       
        user = User(username=username,email=email)
        user1=UserProfile(user=user.request, score=user.score)

        user.save()
        user1.save()      
    return user

但是当新用户访问此应用程序时，他的姓名和分数不会被存储。他的所有 facebook 数据都存储在 facebook 模型中。 请帮助我。

最稳健的方法是使用信号:

class UserProfile(models.Model):
    user = OneToOneField( User, editable = False )   #<----One to One! Not FK.
    score = models.IntegerField(max_length = 50, default = 0) 

#
# this few lines of code in your UserProfile models.py will 
# create the profile just after user is created.
#
from django.dispatch import receiver
from django.db.models.signals import post_save
@receiver(post_save, sender=User)
def createProfile(sender, instance, created, **kwargs):
    if created:
        UserProfile.objects.create( user = instance, )
