Django admin - 如何在自定义管理表单中为多对多字段添加绿色加号
当我在表单中定义多选字段(照片)时,用于在管理表单中添加新实例的绿色加号按钮消失。即,删除带有定义的行 (photos = ...) 会使加号出现。但是,为了使用自定义字段/小部件,我需要弄清楚这一点。
class GalleryForm(ModelForm):
photos = ModelMultipleChoiceField(queryset=Photo.objects.all(), label="Photos")
def __init__(self, *args, **kwargs):
super(GalleryForm, self).__init__(*args, **kwargs)
我查看了 Django 源代码,似乎我必须将我的小部件包装在RelatedFieldWidgetWrapper 中,但我还没有完全理解它。任何帮助表示赞赏!
The green plus sign button for adding new instances in the admin form disappears for my MultiSelect field (photos) when I define it in my form. Ie, removing the line with the definition (photos = ...) makes the plus sign appear. However, in order to use a custom Field/Widget I need to figure this out.
class GalleryForm(ModelForm):
photos = ModelMultipleChoiceField(queryset=Photo.objects.all(), label="Photos")
def __init__(self, *args, **kwargs):
super(GalleryForm, self).__init__(*args, **kwargs)
I've peeked at the Django source code and it seems like I have to wrap my widget in a RelatedFieldWidgetWrapper, but I haven't quite gotten my head around it. Any help is apprecietad!

With the help from lazerscience and this post I ended up with the following.

And my form:
是的,你是对的,你必须用 django.contrib.admin.widgets.RelatedFieldWidgetWrapper 来包装你的小部件,这有点复杂,因为它需要当前管理站点作为初始化参数!也许您会发现这篇帖子对您有帮助!
Yes you are right, you have to wrap your widget with
django.contrib.admin.widgets.RelatedFieldWidgetWrapper
, which turns out to be a bit complicated since it expects the current admin site as a parameter for initialization! Maybe you will find this post helpful!
