Django 基于类的泛型UpdateView内联

我有以下型号

class Cv(models.Model):
    name = models.CharField(_('name'), max_length=250)
    objective = models.CharField(_('objective'), max_length=250)
    slug = models.SlugField(editable=False)

class Position(models.Model):
    cv = models.ForeignKey(Cv, verbose_name=_('cv'))
    start = models.DateField(_('start'))
    end = models.DateField(_('end'))
    name = models.CharField(_('name'), max_length=250)
    currently_employed = models.BooleanField(_('currently employed'))
    sector = models.IntegerField(_('sector'), choices=SECTOR_CHOICES)
    duties = models.TextField(_('duties'))

及下列表格:

class CvForm(ModelForm):
    class Meta:
        model = Cv

class PositionForm(ModelForm):
    class Meta:
        model = Position
        widgets = {
            'start': DateInput(attrs={'class':'datepicker'}),
            'end': DateInput(attrs={'class':'datepicker'}),
        }

PositionFormSet = inlineformset_factory(Cv, Position, form=PositionForm, extra=1)

我创建了以下通用CreateView，效果非常好：

class CreateCvView(CreateView):
    model = Cv
    form_class = CvForm
    template_name = 'recruitment/cv/cv_detail.html'

    def get_success_url(self):
        self.success_url = '/'
        return self.success_url

    def get_context_data(self, **kwargs):
        context = super(CreateCvView, self).get_context_data(**kwargs)
        if self.request.POST:
            context['position_form'] = PositionFormSet(self.request.POST)
        else:
            context['position_form'] = PositionFormSet(instance=self.object)
        return context

    def form_valid(self, form):
        self.object = form.save(commit=False)
        self.object.slug = slugify(self.request.user)
        context = self.get_context_data()
        position_form = context['position_form']
        if position_form.is_valid():
            self.object = form.save()
            position_form.instance = self.object
            position_form.save()
            return HttpResponseRedirect(self.get_success_url())
        else:
            return self.render_to_response(self.get_context_data(form=form))

我想做的是更新视图，因此我复制了createview并将slug传递给它，如下所示：

class EditCvView(UpdateView):
    model = Cv
    form_class = CvForm
    template_name = 'recruitment/cv/cv_detail.html'

    def get_success_url(self):
        self.success_url = '/'
        return self.success_url

    def get_context_data(self, **kwargs):
        context = super(EditCvView, self).get_context_data(**kwargs)
        if self.request.POST:
            context['position_form'] = PositionFormSet(self.request.POST)
        else:
            context['position_form'] = PositionFormSet(instance=self.object)
        return context

    def form_valid(self, form):
        self.object = form.save(commit=False)
        self.object.slug = slugify(self.request.user)
        context = self.get_context_data()
        position_form = context['position_form']
        if position_form.is_valid():
            self.object = form.save()
            position_form.instance = self.object
            position_form.save()
            return HttpResponseRedirect(self.get_success_url())
        else:
            return self.render_to_response(self.get_context_data(form=form))

它可以很好地加载表单，但是当我发布表单时，在get_context_数据中的PositionFormSet（self.request.post）上会出现“列表索引超出范围”错误。还有其他人有此问题吗？

在EditCvView中：

上下文['position\u form']=PositionFormSet（self.request.POST，instance=self.object）

在EditCvView中：

---

context['position\u form']=PositionFormSet（self.request.POST，instance=self.object）

谢谢！！无论如何，我发现这几乎做了所有的事情，所以我使用内联的创建和更新视图。谢谢！！无论如何，我发现这个几乎可以做所有事情，所以我使用了这个的内联创建和更新视图。我放弃了表单集，我像这样创建我的表单集，只需要5项：PurchaserChoiceFormset=inlineformset\u工厂（工作表，PurchaserChoice，form=PurchaserChoiceForm，can_delete=False，extra=5，max_num=5）创建第五个项目并重新保存表单后，它将创建一个新的额外购买选择项目！我的保存代码是：if context['Choice\u formset']。是否有效（）：context['Choice\u formset'].instance=context['sheet']context['choice\u formset'].save（）我放弃了表单集，我这样创建了我的表单集，只需要5项：PurchaserChoiceFormset=inlineformset\u工厂（工作表，PurchaserChoice，form=PurchaserChoiceForm，can\u delete=False，extra=5，max\u num=5）创建第5个项目并重新保存表单后，它将创建一个新的额外购买选择项目！我的保存代码是：if context['Choice\u formset'].is\u valid（）：context['Choice\u formset'].instance=context['sheet']context['Choice\u formset'].save（）
