peewee InternalError: (1054, u"Unknown column 't1.pk' in 'field list'")[peewee 小伙伴求助]

大家好，我用 peewee 建标的时候出现一个问题， 当我查询 MyModel.select().first()报错 InternalError: (1054, u"Unknown column 't1.pk' in 'field list'") , 不用 mysql connection pool 的时候没问题. 也可以 MyModel.create(other_field='XXX')新建数据 .

from peewee import * from playhouse.db_url import connect mysql_db = connect('mysql+pool://root:[email protected]:3306/test?max_cOnnections=20&stale_timeout=300') class MySqlPrimaryKeyAutoIncrementField(BigIntegerField): def __init__(self, *args, **kwargs): kwargs['primary_key'] = True super(MySqlPrimaryKeyAutoIncrementField, self).__init__(*args, **kwargs) def __ddl__(self, column_type): ddl = super(MySqlPrimaryKeyAutoIncrementField, self)__ddl__(column_type) return ddl + [SQL('auto_increment')] class MyModel(Model): pk = MySqlPrimaryKeyAutoIncrementField() other_field = TextField() class Meta: db_table = 'my_model' database = mysql_db 

请问有人遇到么
