我有一个 ModelForm 允许通过 CreateView 的子类创建新的用户对象，我还有一个带有“客户端”字段的 UserProfile 模型，并连接到用户模型。这：
# models.py
class UserProfile(TimeStampedModel):
user = models.OneToOneField(User, unique=True)
client = models.ForeignKey(Client)
# forms.py
class UserForm(ModelForm):
def create_userprofile(self, user, client):
profile = UserProfile()
profile.user = user
profile.client = client
profile.save()
class Meta:
model = User
fields = ('email', 'username', 'password', 'first_name', 'last_name', 'groups')
# views.py
class UserCreate(LoginRequiredMixin, CreateView):
model = User
template_name = 'usermanager/user_form.html'
form_class = UserForm
success_url = reverse_lazy('usermanager:list')
def form_valid(self, form):
### Make sure a newly created user has a UserProfile.
# some pseudo-code thrown in
# First save the user
result = super(UserCreate, self).form_valid(form)
# Now that we have a user, let's create the UserProfile
form.create_userprofile(created_user, current_user.userprofile.client)
# Finally return the result of the parent method.
return result
我希望能够在提交表单时创建一个新的 UserProfile（并且当然是有效的），所以我在 CreateView.form_valid() 方法上执行此操作，但我需要刚刚创建的用户的 ID，它那时我不认为我有——是吗？
同时，我需要为新的 UserProfile 分配与当前（不是新）用户在其个人资料中的相同客户端。
关于如何实现这一目标的任何想法？
