如何使用SQLalchemy和Alembic自动初始化数据库? [英] How can I initialize the database automatically with SQLalchemy and Alembic?

问题描述

当前，我跑步

$ flask db init
$ flask db migrate -m "initialization"
$ flask db upgrade

如果数据库不存在.我想在Python中运行此程序，例如像

if the database does not exist. I would like to run this within Python, e.g. something like

app.create_db()

这样我就不必在意设置数据库了.有可能吗?

so that I don't have to care about setting the database up. Is that possible?

我使用了 flask-sqlalchemy 和 flask-migrations 插件

推荐答案

很显然，您已经安装了 flask-migrate，flask-sqlalchemy .

Obviously, you have installed flask-migrate, flask-sqlalchemy.

因此，您可以这样做:

from flask_sqlalchemy import SQLAlchemy
from flask import Flask

app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:////tmp/test.db'
db = SQLAlchemy(app)
db.create_all()

API DOC:flask.ext.sqlalchemy.SQLAlchemy.create_all

但是您的问题使我感到困惑.为什么受 SQLAlchemy 和 Alembic 限制?

but your Question has confused me. why restricted by SQLAlchemy and Alembic?
