Django Admin自定义表单不保存

Question

我有一个自定义的 Django 管理员，我在其中指定了一个模板和一个要使用的自定义表单

class StoryAdmin(BaseAdmin):
    form = Edit_Story_Form
    change_form_template = "CMS/Editorial/AdminStory/AdminStory.html"

    def change_view(self, request, object_id, form_url='', extra_context=None):
        extra_context = extra_context or {}
        thing = Story.objects.get(pk=object_id)
        extra_context['workflowstate'] = thing.workflowstate.title()
        extra_context['last_updated'] = thing.updateddate
        return super(StoryAdmin, self).change_view(request, object_id, form_url, extra_context=extra_context)

admin.site.register(Story, StoryAdmin)

表格如下：

class Edit_Story_Form(ModelForm):
headline = forms.CharField()
subheadline = forms.CharField()
add_block = forms.CharField(widget=forms.HiddenInput(), label='', required=False)

class Meta:
    model = Story
    fields = []

def __init__(self, *args, **kwargs):
    self.request = kwargs.pop('request', None)
    request = self.request
    super(Edit_Story_Form, self).__init__(*args, **kwargs)
    zones = Zone.objects.filter(story=self.instance)
    for zone in zones:
        zone.form = Edit_Zone_Form(
            request.POST or None,
            request.FILES or None,
            instance = zone,
            prefix = "zone_"+str(zone.id),
        )
        blocks = Block.objects.filter(zone=zone).filter(has_parent=False)
        for block in blocks:
            block_forms = {
                "Text":     Edit_Text_Block_Form,
                "Image":    Edit_Image_Block_Form,
                "Video":    Edit_Video_Block_Form,
                "Embed":    Edit_Embed_Block_Form,
                "Code":     Edit_Code_Block_Form,
                "Live Blog":Edit_Live_Blog_Block_Form,
                "Tweet":    Edit_Tweet_Block_Form,
                "Quiz":     Edit_Quiz_Block_Form,
                "Slideshow":Edit_Slideshow_Block_Form,
                "Curated":  Edit_Curated_Block_Form
            }
            block.form = block_forms[block.block_type](
                request.POST or None,
                request.FILES or None,
                instance = block.get_instance(),
                prefix = "block_"+str(block.id),
            )

def save(self, *args, **kwargs):
    print("HI")
    super(Edit_Story_Form, self).save(*args, **kwargs)

如果我在表单中取出自定义保存方法，它工作正常，并且表单的字段保存。但是，我将需要覆盖保存，因为此表单中包含其他表单，我将在保存时对其进行验证。

添加我的 save 方法会使页面抛出错误：

AttributeError at /admin/Editorial/story/1/
'NoneType' object has no attribute 'save'

我已经看到了对 admin 的 save_object 方法的引用，但由于我实际上希望保存我的表单对象，所以我认为这不是我想要的。为什么我可能会收到此错误的任何想法？

谢谢！

我想你忘记了 return 声明

def save(self, *args, **kwargs):
    print("HI")
    return super(Edit_Story_Form, self).save(*args, **kwargs)
