Question

好的，所以我有一个带有几个inlineformset_factory添加的通用CreateView。与此处的示例类似： Django class-based CreateView and UpdateView with multiple inline formsets

一个是使用父模型按预期生成一个新记录，但是第二个只包含布尔字段的记录不是。我没有为内联formset生成我自己的模型表单，而是使用默认值。一旦我将一个charfield字段添加到违规模型中，保存工作，我可以看到新记录，在该内联formset（和模型）中只有布尔字段，我什么也没有记录，也没有错误。

编辑代码示例＆gt;

#models.py
class Mentor(models.Model):
    title = models.CharField(max_length=15, choices=SALUTATION_CHOICES, blank=True, null=True)
    first_name = models.CharField(blank=False, null=False, max_length=80)
    last_name = models.CharField(blank=False, null=False, max_length=80)

class MentorSetting(models.Model):
    mentor = models.OneToOneField('Mentor')
    mentor_status = models.BooleanField(default=True)
    question_status = models.BooleanField(default=True)

#forms.py
class MentorForm(ModelForm):
    class Meta:
        model = Mentor
        fields = ['title','first_name','last_name',]

SettingsFormSet = inlineformset_factory(Mentor, MentorSetting,
        fields=('mentor_status','question_status',),
        extra=1,
        can_delete=True)

#views.py
class MentorCreateView(CreateView):
    template_name = 'mentor/mentor_form.html'
    model = Mentor
    form_class = MentorForm

    def get(self, request, *args, **kwargs):
        self.object = None
        form_class = self.get_form_class()
        form = self.get_form(form_class)
        settings_form = SettingsFormSet()
        return self.render_to_response(
            self.get_context_data(form=form,                                 
                                  settings_form=settings_form))

    def post(self, request, *args, **kwargs):
        self.object = None
        form_class = self.get_form_class()
        form = self.get_form(form_class)
        settings_form = SettingsFormSet(self.request.POST)
        if (form.is_valid() and settings_form.is_valid()):
            return self.form_valid(form, settings_form)
        else:
            return self.form_invalid(form, settings_form)

    def form_valid(self, form, settings_form):
        self.object = form.save()
        settings_form.instance = self.object
        settings_form.save()
        return HttpResponseRedirect(self.get_success_url())

    def form_valid(self, form, settings_form):
        return self.render_to_response(
            self.get_context_data(form=form,
                                  settings_form=settings_form))

如果有人能解释为什么会很棒。

具有内联形式的CreateView，仅具有布尔值的字段无法创建
