Question

我正在尝试清理我的内联formset数据。我有三个规则：1）必须提供至少一个名称，2）如果指定名称，则必须指定第一个和最后一个，以及3）没有空格。保存数据后，空间仍保存到数据库中。我做错了什么？

另一个问题是未显示验证错误。那是为什么？

forms.py:
class UserNameForm(forms.models.BaseInlineFormSet):
    def clean(self):
        super(UserNameForm, self).clean()
        count = 0
        for form in self.forms:
            try:
                firstName = form.cleaned_data.get("name_first")
                middleName = form.cleaned_data.get("name_middle")
                lastName = form.cleaned_data.get("name_last")
                if firstName or middleName or lastName:
                    if len(firstName) == 0 or len(lastName) == 0:
                        raise forms.ValidationError("First and Last name are required.")

                if form.cleaned_data and not form.cleaned_data.get('DELETE', False):
                    count += 1
                    form.cleaned_data['name_first'] = firstName.replace(" ",'')
                    form.cleaned_data["name_middle"] = middleName.replace(" ",'')
                    form.cleaned_data["name_last"] = lastName.replace(" ",'')
            except AttributeError:
                pass
        if count < 1:
            raise forms.ValidationError('You must have at least one order')

views.py
UserNameFormSet = inlineformset_factory(Profile, Alias, formset=UserNameForm, extra=2, can_delete=True )
if request.method == 'POST':
    cNameFormSet = UserNameFormSet(request.POST, request.FILES, instance=cProfile)
    if cNameFormSet.is_valid():
        testResults  = cNameFormSet.save(commit=False)
        for form in testResults:
            form.save()

您可以同时应用表单和表单集。使用formset验证表单和表单中的数据，以验证表单中的数据并引发验证错误。

UserNameFormSet = inlineformset_factory(Profile,
                                        Alias,
                                        form=UserNameForm,
                                        formset=AtLeastOne,
                                        extra=2,
                                        can_delete=True )

class AtLeastOne(forms.models.BaseInlineFormSet):
    def clean(self):
        count = 0
        for form in self.forms:
            try:
                if form.cleaned_data and not form.cleaned_data.get('DELETE', False):
                    count += 1
            except AttributeError:
                pass
        if count < 1:
            raise forms.ValidationError('You must have at least one name')

class UserNameForm(forms.ModelForm):
   class Meta:
        model = Alias
   def clean(self):
       cleaned_data = self.cleaned_data
       # Check 1: Must have first and last.
       firstName = cleaned_data.get("name_first")
       middleName = cleaned_data.get("name_middle")
       lastName = cleaned_data.get("name_last")
       if firstName or middleName or lastName:
           if len(firstName) == 0 or len(lastName) == 0:
               raise forms.ValidationError("First and Last name are required.")
       # Check 2: No spaces.
       cleaned_data["name_first"] = firstName.replace(" ",'')
       cleaned_data["name_middle"] = middleName.replace(" ",'')
       cleaned_data["name_last"] = lastName.replace(" ",'')
       return cleaned_data

BaseInlineFormSet不会清除无效字符
