API Star的Peewee集成。
功能
此库提供：
- 根据视图中的异常处理connections和commit/rollback行为的事件挂钩。
- 迁移支持与它们交互的命令行界面。
快速启动
安装API Star Peewee orm:
pip install apistar-peewee-orm
创建一个api之星应用程序，添加组件和事件挂钩：
fromapistarimportAppfromapistar_peewee_ormimportPeeweeDatabaseComponent,PeeweeTransactionHookroutes=[]components=[PeeweeDatabaseComponent(url='sqlite://'),]event_hooks=[PeeweeTransactionHook(),]app=App(routes=routes,components=components,event_hooks=event_hooks)
您的模型现在应该继承自此库中定义的基本模型：
importpeeweefromapistar_peewee_ormimportModelclassPuppyModel(Model):name=peewee.CharField()

cli应用程序
将与此库一起安装一个应用程序，以提供对迁移和某些其他功能的完全支持 皮威和API之星。
$ apistar-peewee-orm --help
usage: apistar-peewee-orm [-h] [-s SETTINGS] [-q | -v] [--dry-run]
{status,upgrade,downgrade,merge,create} ... [app]

(<package>.<module>:<variable>)
optional arguments:

-s SETTINGS, --settings SETTINGS
Module or object with Clinner settings in format
"package.module[:Object]"
-q, --quiet Quiet mode. No standard output other than executed
application
-v, --verbose Verbose level (This option is additive)
--dry-run Dry run. Skip commands execution, useful to check
which commands will be executed and execution order
Commands:
{status,upgrade,downgrade,merge,create}
status Database migrations and models status.
upgrade Run database migrations sequentially.
downgrade Rollback database migrations sequentially.
