如何解决Django - 模型表单集 - 前端验证不起作用？

我正在使用模型表单集。这是我的表格：

class UnloadForm(forms.ModelForm):
    class Meta:
        model = Unload
        fields = ''__all__''

    def __init__(self,*args,**kwargs):
        super().__init__(*args,**kwargs)
        self.fields[''fieldContract''].queryset = FieldContract.objects.filter(applicativeContract__contract__is_active=True).order_by(''applicativeContract__contract__internal_code'',''applicativeContract__internal_code'',''internal_code'')
        self.fields[''product''].queryset = Product.objects.all().order_by(''name'')


class BaseUnloadFormset(BaseModelFormSet):
    def clean(self):
        super().clean()

        for form in self.forms:
            cd = form.cleaned_data
            whouse = cd[''whouse'']
            company = cd[''company'']
            product = cd[''product'']
            quantity = cd[''quantity'']
            movement_date = cd[''movement_date'']
            helper = StockHelper(product,whouse,company,movement_date)
            if quantity > helper.stock:
                raise ValidationError(f''Attenzione quantità massima disponibile di {product}: {helper.stock}'')
            return cd

UnloadFormSet = modelformset_factory(
    model = Unload,fields = ''__all__'',extra = 5,form = UnloadForm,formset=BaseUnloadFormset
)

class UnloadFormSetHelper(FormHelper):
    def __init__(self,**kwargs)
        self.form_tag = False
        self.layout = Layout(
            Row(
                ''whouse'',''fieldContract'',''company'',''product'',''quantity'',''movement_date'',)
        )
        self.render_required_fields = True

当我在 BaseUnloadFormset 中添加了 clean 方法时，问题就出现了。 由于模型中的所有字段都是必需的，例如不说明运动日期会提示前端验证。 不幸的是，虽然网页的源代码显示该字段实际上是必需的，但忘记移动日期会将表单发送到后端，最终系统会崩溃，因为cleaned_data字典中没有移动日期，从而引发KeyError .

我试图按照文档来覆盖干净的方法： Django Docs on overriding the formset clean method

删除表单中的clean方法，将恢复如下图所示的正确行为：

以防万一，这是我的观点：

def unload(request):
    helper = UnloadFormSetHelper()
    context = {
        ''helper'': helper,''title'': ''Nuovo SCarico'',}
    if request.method == ''GET'':
        formset = UnloadFormSet(queryset=Unload.objects.none())
        load_user_companies_in_formset(request,formset)
        context[''formset''] = formset

    elif request.method == ''POST'':
        formset = UnloadFormSet(request.POST)
        context[''formset''] = formset
        load_user_companies_in_formset(request,formset)
        if formset.is_valid():
            formset.save()
            messages.success(request,''Scarico salvato correttamente'',fail_silently=True)
            return HttpResponseRedirect(reverse(''warehouse:dashboard''))
        else:
            return render(request,''warehouse/unload.html'',context)

    return render(request,context)
