我在处理DjangoModelForm和bootstrap-datepicker以选择特定月份时遇到了一些问题
首先，我得到这个错误，当我访问的形式

The specified value "01/04/2023" does not conform to the required format.  The format is "yyyy-MM" where yyyy is year in four or more digits, and MM is 01-12

在手动选择月份后，

periodo: Enter a valid date.
limite_retroactividad: Enter a valid date.

我试着用JavaScript脚本来处理它，但它只对初始日期有效，而不是保存数据。
这就是我所拥有的：

forms.py

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

    def clean(self):
        cleaned_data = super().clean()
        periodo = cleaned_data.get('periodo')
        limite_retroactividad = cleaned_data.get('limite_retroactividad')

        if periodo and limite_retroactividad:
            if periodo < limite_retroactividad:
                # Add validation error
                self.add_error('limite_retroactividad', 'El periodo no puede ser menor al límite de retroactividad')
        return cleaned_data

    class Meta:
        model = RegistroGestion
        fields = ['periodo', 'estado', 'limite_retroactividad']
        widgets = {
            'limite_retroactividad': DateInput(
                attrs={
                    'type': "month",
                    'class': "form-select mb-3"
                }
            ),
            'periodo': DateInput(
                attrs={
                    'type': "month",
                    'class': "form-select mb-3"
                }
            ),
        }

views.py

class RegistroGestionUpdateView(UpdateView):
    model = RegistroGestion
    form_class = RegistroGestionForm
    context_object_name = 'registro_gestion'
    template_name = 'esquema_liquidacion/registro_gestion_form.html'

    def get_context_data(self, **kwargs: Any) -> dict[str, Any]:
        context = super().get_context_data(**kwargs)
        context['update'] = True
        return context

    def get_success_url(self):
        return reverse('registro-gestion-list')

    def form_valid(self, form):
        if form.is_valid():
            # Perform custom actions if needed
            return super().form_valid(form)
        else:
            # Handle the case where the form is not valid
            # You can add debugging output or log errors here
            return self.render_to_response(self.get_context_data(form=form))
