以下是翻译好的部分：
这些内容已经在这里记录下来：http://docs.peewee-orm.com/en/latest/peewee/models.html#self-referential-foreign-keys
```python
class Department(BaseModel):
parent = ForeignKeyField('self', null=True, backref='children')
name = CharField()
示例用法：
root = Department.create(name='root')
d1 = Department.create(parent=root, name='Dept 1')
# 等等。
