Django表單無法保存到表

Question

這就是問題所在-用戶按下“保存”按鈕時，他們輸入的設置應保存到表格中。 但是，這不會發生。 重定向后，您可以再次檢查“設置”頁面或管理站點，更改不會出現。 我什至放了幾條全部運行的打印語句，但我不知道為什么會這樣。 這是代碼（我只包含了必要的內容）

views.py

class SettingsView(LoginRequiredMixin, FormView):
template_name = 'example/settings.html'
form_class = ExampleSettingsForm
success_url = reverse_lazy('example:index')

def get_context_data(self, **kwargs):
    context = super(SettingsView, self).get_context_data(**kwargs)
    context['page'] = 'settings'
    return context

def get_initial(self):
    initial = super(SettingsView, self).get_initial()

    initial['example1'] = self.request.user.example.example1
    initial['example2'] = self.request.user.example.example2
    initial['example3'] = self.request.user.example.example3
    initial['example4'] = self.request.user.example.example4
    initial['example5'] = self.request.user.example.example5
    initial['example6'] = self.request.user.example.example6
    initial['example7'] = self.request.user.example.example7

    return initial

def form_valid(self, form):
    form.save_to_example(self.request.user)
    print("Form valid.")
    return super(SettingsView, self).form_valid(form)

@method_decorator(shelter_login_required)
def dispatch(self, *args, **kwargs):
    return super(SettingsView, self).dispatch(*args, **kwargs)

forms.py

class ExampleSettingsForm(forms.Form):
example1 = forms.CharField()

example2 = forms.TimeField()
example3 = forms.TimeField()

example4 = AddressField()

example5 = forms.IntegerField()

example6 = forms.RegexField(regex=r'^\+?1?\d{9,15}$')

example7 = forms.BooleanField()

def save_to_example(self, user):
    user.example.example1 = self.cleaned_data['example1']
    user.example.example2 = self.cleaned_data['example2']
    user.example.example3 = self.cleaned_data['example3']
    user.example.example4 = self.cleaned_data['example4']
    user.example.example5 = self.cleaned_data['example5']
    user.example.example6 = self.cleaned_data['example6']
    user.example.example7 = self.cleaned_data['example7']
    user.save()
    print(user.example.example1)

models.py

class Example(models.Model):
    example1 = models.CharField(max_length=200)

    example2 = models.TimeField(null=True)
    example3 = models.TimeField(null=True)

    example_male = models.IntegerField(default=0)
    example_female = models.IntegerField(default=0)

    example6 = models.IntegerField(default=10)

    example5 = AddressField(null=True, on_delete=models.CASCADE)

    user = models.OneToOneField(User, on_delete=models.CASCADE)

    example7 = models.BooleanField(default=False)

    example_regex = RegexValidator(regex=r'^\+?1?\d{9,15}$', message="Phone number must be entered in the format: '+999999999'. Up to 15 digits allowed.")
    example_number = models.CharField(validators=[phone_regex], max_length=17, blank=True)

@receiver(post_save, sender=User)
def create_user_example(sender, instance, created, **kwarg):
    if created:
        Example.objects.create(user=instance)

@receiver(post_save, sender=User)
def save_user_example(sender, instance, **kwargs):
    if not instance.is_superuser:
        instance.example.save()

注意-我知道縮進不正確。 我在復制/粘貼到堆棧溢出時遇到了麻煩。

嘗試這個：

def save_to_example(self, user):
    example = user.example
    example.example1 = self.cleaned_data['example1']
    example.example2 = self.cleaned_data['example2']
    example.example3 = self.cleaned_data['example3']
    example.example4 = self.cleaned_data['example4']
    example.example5 = self.cleaned_data['example5']
    example.example6 = self.cleaned_data['example6']
    example.example7 = self.cleaned_data['example7']
    example.save()
    print(example.example1)
