Ограничение выбора формы с помощью django

Question

Как я могу ограничить выбор в django formset до максимального числа 5. Мои взгляды как:

file_attachment_formset = get_audioattachment_formset(FileAttachmentForm, extra=1, can_delete=True)

мои формы как:

class FileAttachmentForm(forms.ModelForm):
    class Meta:
        model = FileAttachment

    def __init__(self, *args, **kw):
        super(forms.ModelForm, self).__init__(*args, **kw)
        self.fields['audio_video'].widget.attrs['class'] = 'form-text'

def get_audioattachment_formset(form, formset = models.BaseInlineFormSet, **kwargs):
    return models.inlineformset_factory(Post, FileAttachment, form, formset, **kwargs)

Models.py:

class FileAttachment(models.Model):
    post          = models.ForeignKey(Post, related_name = 'file_attachments')
    picture       = models.ImageField(upload_to = 'uploads/picture/', null = True, blank = True)
    audio_video   = models.URLField(null = True, blank = True, verbose_name = "Audio/Video URL", verify_exists = True)

views.py:

file_attachment_formset = get_audioattachment_formset(FileAttachmentForm, extra=1, can_delete=True, max_num=3)
if request.method == 'POST':
   postForm = MyPostForm(request.POST, instance = post)
   formset = file_attachment_formset(request.POST, request.FILES, instance = post)
   if formset.is_valid():
                #FileAttachment.objects.filter(post = newpost).delete()
                formset = file_attachment_formset(request.POST, request.FILES, instance = newpost)
                formset.save()
   else:
       formset = file_attachment_formset(instance = post)  

Помогите мне Как я могу ограничить выбор картинок максимум 5?

Проходить max_num с функцией formset,

file_attachment_formset = get_audioattachment_formset(FileAttachmentForm, extra=1, can_delete=True, max_num=5)

Это мое предположение, обычно форма занимает max_num как карг. Попробуйте!
