如何在 Django Admin 中使用 can_add_related

2022-01-25 00:00:00 python django django-admin

问题描述

我在这里阅读了有关 can_add_related 功能:https://code.djangoproject.com/ticket/9071

I've read about the can_add_related feature here: https://code.djangoproject.com/ticket/9071

我试过这样使用它:

def get_form(self, request, obj=None, **kwargs):
    self.fields['person'].can_add_related = False
    return super(OperationAdmin, self).get_form(request, obj, **kwargs)

但这会引发 TypeError，我不知道如何解决.

But this throws a TypeError and I don't know how to solve this.

有人能指出正确的方向吗?

Can someone point me in the right direction?

谢谢.

解决方案

这可能来晚了.但供其他观众参考，

This is probably coming in late. But for other viewers reference, 

def get_form(self, request, obj=None, **kwargs):
    form = super(ProductAdmin, self).get_form(request, obj, **kwargs)
    form.base_fields['category'].widget.can_add_related = False
    return form
