Python peewee:在混合属性的模型类中引用self值

from peewee import *

db = SqliteDatabase('my_database.db')

class Person(Model):
    name = CharField()
    parent = DeferredRelation('self')

    class Meta:
        database = db

db.create_tables([Person])

# 创建一些示例数据
person1 = Person.create(name='Alice')
person2 = Person.create(name='Bob')
person3 = Person.create(name='Charlie')

# 设置父子关系
person2.parent = person1
person3.parent = person2

# 保存更改
person2.save()
person3.save()

# 查询某个人的父亲
person = Person.get(Person.name == 'Charlie')
father = person.parent

print(father.name)  # 输出：Bob
