Question

我正在尝试添加一项功能，以便新用户在初次登录时需要更新他/她的密码。我在我的Profile模型中添加了一个隐藏的BooleanField，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，当我在views.py中尝试使用force_password_change时，它永远不会返回我在django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.")

目前正在给我这个错误

Traceback (most recent call last):
File "C:\Python34\lib\site-packages\django\core\handlers\exception.py", line 
   41, in inner
   response = get_response(request)
File "C:\Python34\lib\site-packages\django\core\handlers\base.py", line 187, 
   in _get_response
   response = self.process_exception_by_middleware(e, request)
File "C:\Python34\lib\site-packages\django\core\handlers\base.py", line 185, 
   in _get_response
   response = wrapped_callback(request, *callback_args, **callback_kwargs)
File "start\views.py", line 20, in user_login
   changepass = UserProfile.objects.get(user=request.user)
File "C:\Python34\lib\site-packages\django\db\models\manager.py", line 85, 
   in manager_method
   return getattr(self.get_queryset(), name)(*args, **kwargs)
File "C:\Python34\lib\site-packages\django\db\models\query.py", line 380, in 
   get
   self.model._meta.object_name
   start.models.DoesNotExist: UserProfile matching query does not exist.

我还在我的settings.py中添加了AUTH_PROFILE_MODULE = 'start.UserProfile'，这似乎不是问题所在。

您忘记使用受尊敬的用户

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…)

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

在view.py中使用的Django布尔字段
