用户在更新Django时丢失管理统计信息

Question

I have the following code to edit the user:

View.py

@login_required()
def edit_user_profile(request):

if request.method == 'POST':
    profile_form = ProfileForm(request.POST, instance=request.user.profile)
    user_form = UserForm(request.POST, instance=request.user, request=request)
    city_form = CityForm(request.POST)

    if profile_form.is_valid() and user_form.is_valid() and city_form.is_valid():

        # Updates profile
        try:
            user_profile = profile_form.save(commit=False)
            user_profile.user = user_form.save()
            user_profile.city = city_form.get_instance()

            # Save instance
            user_profile.save()
        except Exception:
            raise

        # Checks if user came from another page
        previous_page = request.GET.get('next', None)
        if previous_page:
            return HttpResponseRedirect(previous_page)

        return redirect(profile_update_success)
else:

    profile_form = ProfileForm(instance=request.user.profile)
    user_form = UserForm(instance=request.user)
    city_form = CityForm(initial={'post_nr': request.user.profile.get_city_post_code(), 'city': request.user.profile.get_city_name()})

return render(request, 'user/profile.html',
              {
                  'user': request.user,
                  'profile_form': profile_form,
                  'user_form': user_form,
                  'city_form': city_form,
              })

Forms.py

class UserForm(ModelForm):
    first_name = forms.CharField(required=True, max_length=10, widget=forms.TextInput(attrs={'placeholder': 'First name'}))
    last_name = forms.CharField(required=True, max_length=20, widget=forms.TextInput(attrs={'placeholder': 'Last name'}))
    email = forms.EmailField(required=True, widget=forms.TextInput(attrs={'placeholder': 'E-mail'}))

    class Meta:
        model = User
        exclude = ('username', 'password', 'date_joined', )

    def clean_email(self):
        email = self.cleaned_data['email']

        try:
            user = User.objects.get(email=email)
            if self.instance.username != user.username:
                raise forms.ValidationError("This e-mail is already in use.")
        except User.DoesNotExist:
            pass
        return email

    def __init__(self, *args, **kwargs):
        self.request = kwargs.pop('request', None)
        super(UserForm, self).__init__(*args, **kwargs)


class ProfileForm(ModelForm):
    class Meta:
        model = UserProfile
        exclude = ('city', 'user',)
        widgets = {
            'company_name': forms.TextInput(attrs={'placeholder': "*Optional company name"}),
            'telephone': forms.TextInput(attrs={'placeholder': "*Optional telephone number"}),
            'mobile': forms.TextInput(attrs={'placeholder': "Mobile number"}),
        }

The problem happens every time the user updates his/her information. The account is set as "inactive". The same thing happens with administrators and they lose their "staff" and "superuser" status.

I have also the following signal that does not work when ignoring the admin status. It does help preventing the account being set to "inactive".

@receiver(pre_save, sender=User)
def update_username_from_email(sender, instance, **kwargs):
    if not instance.email or instance.is_superuser:
        return
    instance.username = instance.email
    instance.is_active = True

The user does get updated however I have these "collateral effects".

As you can see on the Django User Model those permissions you speak of are fields which you are not excluding from 'UserForm' and thus are setting False since you are seemingly not providing a value in the request.POST data. To be 100% it would help to see how you are rendering the form, but this is most likely the problem.
