我正在使用 Python 3.3 32 位在 Windows 上工作。我已经安装了 peewee 并想尝试它的一些功能。我从 Peewee 快速入门 ( http://peewee.readthedocs.org/en/latest/peewee/quickstart.html ) 开始。
我的代码如下所示:
from peewee import *
db = SqliteDatabase('people.db')
class Person(Model):
name = CharField()
birthday = DateField()
is_relative = BooleanField()
class Meta:
database = db
class Pet(Model):
owner = ForeignKeyField(Person, related_name = "pets")
name = CharField()
animal_type = CharField()
class Meta:
database = db
Person.create_table()
Pet.create_table()
我得到一个错误:
File "<stdin>", line 1, in <module>
File "<string>", line 21, in <module>
File "C:\Python33\lib\site-packages\peewee.py", line 2094, in create_table
db = cls._meta.database
AttributeError: type object 'Person' has no attribute '_meta'
我的 peewee 安装有问题吗?我该如何解决这个问题?
