Python view.py中使用的Django布尔字段

我正在尝试添加一个新用户在初次登录时需要更新其密码的功能。我在配置文件模型中添加了一个隐藏的布尔字段，其中default=True

models.py

class UserProfile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    force_password_change = models.BooleanField(default=True)

但是，当尝试在myviews.py中使用force\u password\u change时，它永远不会返回我在django的管理页面中设置的正确值

views.py

if request.method == 'POST':
    ...
    user = authenticate(request, username=username, password=password)
    changepass = UserProfile.objects.get(user=request.user)
    if user:
        if changepass.force_password_change == True:
            changepass.force_password_change = False
            changepass.save()
            return HttpResponseRedirect('/login/register/')
        elif changepass.force_password_change == False:
            if user.is_active:
                login(request, user)
                return HttpResponseRedirect('/main/')
            else:
                return HttpResponse("Your account has been disabled.")

它现在给了我这个错误

Traceback (most recent call last):
File "C:\Python34\lib\site-packages\django\core\handlers\exception.py", line 
   41, in inner
   response = get_response(request)

我还在我的settings.py中添加了

AUTH\u PROFILE\u MODULE='start.UserProfile'

，所以这似乎不是问题。

这与布尔字段无关。错误告诉您您的特定用户在UserProfile表中没有相关条目。

您忘记了与受尊敬的用户一起创建UserProfile

from django.db.models.signals import post_save
from models import UserProfile
from django.contrib.auth.models import User

def register(request):
    if request.method == 'POST':
        uf = UserForm(request.POST, prefix='user')
        upf = UserProfileForm(request.POST, prefix='userprofile')
        if uf.is_valid() and upf.is_valid():
            user = uf.save()
            userprofile = upf.save(commit=False)
            userprofile.user = user
            userprofile.save() # Are you missing this line ??
            return django.http.HttpResponseRedirect(…something…)

抱歉，我在发布前更改了一些内容。我将如何着手修复当前的错误？我在django admin page users表中有一个用户。创建用户时，您是否专门使用user对象创建了UserProfile。我通过django附带的admin page创建了我的用户。我正在使用UserProfile向其中添加字段。您需要在创建用户对象时为管理员站点编写一个post_save方法。看这条线嘿，谢谢你！我刚刚添加了create_user_配置文件代码。这个问题似乎已经解决了。谢谢。请发表评论并欢迎。
