使用django-mptt和django auth_user

Question

我正在尝试使用django-mptt创建用户树。我有auth_user表和一对一映射表UserProperties，其外键为auth_user。 我在用户表上的TreeForeignKey模型（UserProperties列）中添加了parent django-mptt。但是在创建具有以下错误的对象时失败：

'User' object has no attribute 'is_root_node'

Answer 1

The method (not attribute) 'is_root_node()' is valid on query-items

item = Class.objects.get()

or in iterator or list expression:

[item.is_root_node() for item in Class.objects.filter(name = 'name')]

But to address your question properly, could you give us the code for your model and your query, please.
