seb*_*t26 3 python attributeerror python-3.x peewee
我在使用Python 3.3 32位的Windows上工作.我已经安装了peewee并想尝试它的一些功能.我已经开始使用Peewee Quickstart(http://peewee.readthedocs.org/en/latest/peewee/quickstart.html).
我的代码看起来像这样:
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()

我收到一个错误:

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'

我安装的小便有问题吗?我该如何解决这个问题?
