官網：https://tortoise-orm.readthedocs.io/en/latest/

官網提供的與sanic結合使用的示例：https://tortoise-orm.readthedocs.io/en/latest/examples/sanic.html

 

安裝：pip install tortoise-orm

 

模型

 

與app綁定

 

創建用戶

 

查詢

 

tortoise-orm 要比 SQLALchemy 輕很多，使用也方便很多

 

models

from tortoise import Model, fields


class Users(Model):
    id = fields.IntField(pk=True)
    name = fields.CharField(50)
    age = fields.IntField()

    def __str__(self):
        return f"User {self.id}: {self.name}: {self.age}"

 

main

import logging

from models import Users
from sanic import Sanic, response

from tortoise.contrib.sanic import register_tortoise

logging.basicConfig(level=logging.DEBUG)

app = Sanic(__name__)


@app.get("/user")
async def list_all(request):
    users = await Users.all()
    return response.json({"users": [str(user) for user in users]})


@app.post("/user")
async def add_user(request):
    user = await Users.create(**request.json)
    return response.json({"user": str(user)})


register_tortoise(
    app, db_url="mysql://root:123456@localhost/test", modules={"models": ["models"]}, generate_schemas=True
)

if __name__ == '__main__':
    import uvicorn

    uvicorn.run('main:app', host='0.0.0.0', port=8000, debug=True)
