模板中的Django Formset视图以相反的顺序

我正在使用modelformset_factory并查看模板中的表单集数据。如果您看下面的图片,模板将在第一张图片中显示数据。但我想像第二张图片一样以相反的顺序查看表单集。首先,我将有新数据输入文本框。然后,旧数据将按照相反的顺序列出,就像在第二张图片中一样。

enter image description here

我的模特是:

class AssistantNotes(BaseModel):
    categories = models.CharField(choices=CATEGORIES, max_length=100, verbose_name=_("Kategori"))
    dailynote = models.TextField(null=True, blank=True, verbose_name=_("Not Ekle"))

    def __unicode__(self):
        return "%s / %s" % (self.dailynote, self.categories)

    class Meta:
        ordering = ['dailynote']    

然后我在下面的视图中创建了

def create_assistant_notes(request):
    if request.method == 'GET':
        if AssistantNotes.objects.count() == 0:
            file_write("get000")
            AssistantNotesFormsetFactory = modelformset_factory(AssistantNotes, fields=('categories', 'dailynote',))
        else:
            file_write("get111")
            AssistantNotesFormsetFactory = modelformset_factory(AssistantNotes, fields=('categories', 'dailynote',), can_delete=True)
        formset = AssistantNotesFormsetFactory(queryset=AssistantNotes.objects.all())
        helper = TableInlineHelper()
        return render(request, 'create-assistant-notes.html', {'formset': formset, 'helper': helper})
    elif request.method == 'POST':
        if AssistantNotes.objects.count() == 0:
            AssistantNotesFormsetFactory = modelformset_factory(AssistantNotes, fields=('categories', 'dailynote',))
        else:
            AssistantNotesFormsetFactory = modelformset_factory(AssistantNotes, fields=('categories', 'dailynote',), can_delete=True)
        formset = AssistantNotesFormsetFactory(request.POST)
        if formset.is_valid():
            formset.save()
        else:
            helper = TableInlineHelper()
            return render(request, 'create-assistant-notes.html', {'formset': formset, 'helper': helper})
        return redirect(reverse('create-assistant-notes'))

我的模板html文件是;

{% extends 'base.html' %}
{% load crispy_forms_tags %}    
{% block title %}{% trans "Notes" %}{% endblock title %}    
{% block content %}
<div class="block-area" id="basic">
    <form role="form" method="post">
        {% crispy formset helper %}
        <div class="modal-footer">
            <button type="submit" class="btn btn-sm btn-alt">{% trans "Save" %}</button>
            <button type="button" class="btn btn-sm btn-alt" data-dismiss="modal">{% trans "Cancel" %}</button> 
        </div>
    </form>
</div>
{% endblock content %}
