本文介绍了如何在SQLAlchemy中创建ENUM?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
from sqlalchemy import *
from migrate import *
meta = MetaData()
race_enums = ('asian','mideastern','black','nativeamerican','indian','pacific','hispanic','white','other');
profiles_profiles = Table(
'profiles_profiles', meta,
Column('id', Integer, primary_key = True),
Column('user_id', Integer, nullable=False, unique=True),
Column('race', Enum, race_enums),
Column('summary', Text, nullable= True),
Column('my_life', Text, nullable= True),
Column('to_do', Text, nullable= True),
Column('favs', Text, nullable= True),
Column('created_at', DateTime, nullable=True),
Column('updated_at', DateTime, nullable=True)
)
def upgrade(migrate_engine):
meta.bind = migrate_engine
profiles_profiles.create()
pass
def downgrade(migrate_engine):
meta.bind = migrate_engine
profiles_profiles.drop()
pass
当我manage.py升级这个,我得到这个错误:
When I manage.py upgrade this, I get this error:
AttributeError: 'tuple' object has no attribute '_set_parent_with_dispatch'
推荐答案
您需要传递 race_enum
作为枚举
列
您可以传递元组
整体
Column('race', Enum('asian','mideastern','black','nativeamerican','indian','pacific','hispanic','white','other'))
$ b b
或使用 *
解开 race_enums
:
Column('race', Enum(*race_enums))
