flask-sqlalchemy使用命令创建数据库

# 启动文件
from flask_script import Manager,Server
from flask_migrate import MigrateCommand,Migrate
from rbac import create_app,db
app = create_app()
manager = Manager(app)

migrate = Migrate(app,db)
manager.add_command("runserver",Server())
manager.add_command("db",MigrateCommand)

if __name__ == '__main__':
    manager.run()

# 启动文件启动自动触发
from flask import Flask
from config.setting import BaseConfig

#导入flask-sqlalchemy
from flask_sqlalchemy import SQLAlchemy
db = SQLAlchemy()

from .views.user import user

# 导入models中的表
from .model.models import *

def create_app():
    app = Flask(__name__)
    app.register_blueprint(user)

    db.init_app(app)
    return app
