flask_migrate

flask_migrate 幫助咱們作數據庫的遷移,和Django中的很類似。

from crm import create_app,db
from flask_script import Manager
#作數據庫的遷移
from flask_migrate import Migrate,MigrateCommand

app = create_app()
manager = Manager(app)

Migrate(app,db)
'''
數據庫遷移命令：
python manage.py db init (只須要執行一遍) Django中
python manage.py db migrate ---> makemigration
python manage.py db upgrade ----> migrate 
'''
manager.add_command('db',MigrateCommand)

if __name__ == "__main__":   # app.run()   manager.run()
