Question

我正在使用BaseModelFormSet并将其传递给视图中的modelformset_factory。在BaseModelFormSet函数内部，我重写clean（）进行表单集验证以引起验证错误。问题是当我尝试用错误的数据填充表单集时，验证错误根本不显示

我尝试使用非字段错误手动在模板中进行渲染，但是没有用，并查阅了文档https://docs.djangoproject.com/en/2.1/topics/forms/modelforms/#overriding-clean-on-a-modelformset

更新：如果我故意用错误的数据填充表单，它将仅验证表单集中的第一个表单，而不验证所有表单（扩展名设置为2）

forms.py

class MyModelFormSet(BaseModelFormSet):
    def clean(self):
        super().clean()
        if any(self.errors)
            return

        for form in self.forms:
            debit = form.cleaned_data['debit']
            if debit == 100:
                raise forms.ValidationError('debit is 100!')
            return debit

views.py

def postpage(request):
    journalLineFormSet = modelformset_factory(journalLine,exclude=('journalNumber',),extra=2,can_delete=True,formset=MyModelFormSet,max_num=2,validate_max=True)
    if request.method == 'POST':
        mainform = journalForm(request.POST)
        subform = journalLineFormSet(request.POST)
        if mainform.is_valid() and subform.is_valid():
            instances = subform.save(commit=False)
            for instance in instances:
                instance.save()
            mainform.save()


            return HttpResponseRedirect('/myacc/posted/')

    else:
        ##linesform = linesform(queryset=journal.objects.all().none())
        mainform = journalForm()
        subform = journalLineFormSet(queryset=journalLine.objects.all().none()) #prefix used if you want to set a cumstom prefix to from name

    return render(request,'myacc/post.html',{'mainform': mainform, 'subform': subform})

Django，BaseModelFormSet中的ValidationError
