fastapix-py 0.9.5b2

A FastAPI plugin that quickly builds CRUD-API based on SQLAlchemy

FastAPIX

FastAPIX 为 FastAPI 提供的基于 SQLAlchemy ORM 快速构建数据库操作的插件.

V1.0 后，将去除对pydantic v1的兼容

安装

pip3 install fastapix-py

fastapi

from fastapi import FastAPI

app = FastAPI()

离线挂载 openapi

from fastapix import offline

offline.register_offline_openapi(app)

修改异常返回结果

from fastapix import handlers

handlers.register_exception_handlers(app)

ORM模型

from uuid import UUID, uuid4
from datetime import datetime
from typing import Annotated

from pydantic.functional_serializers import PlainSerializer
from fastapix.crud import SQLModel, Field
from fastapix.common.serializer import convert_datetime_to_chinese

# 自定义类型序列化函数  pydantic V2+
# from fastapix.crud.mixins import CreateTimeMixin 默认以采用 `DATETIME` 序列化
# pydantic V2+
DATETIME = Annotated[datetime, PlainSerializer(convert_datetime_to_chinese)]

# 继承 SQLModel
class Category(SQLModel, table=True):
    """
    测试
    """
    id: UUID = Field(default_factory=uuid4, primary_key=True, nullable=False, create=False, update=False)
    name: str = Field(..., title='名称', max_length=100, index=True, nullable=False, unique=True, update=False)
    
    create_time: DATETIME = Field(default_factory=datetime.now, title="Create Time", create=False, update=False)

# 

DATETIME TIMESTAMP 已内置于 fastapix.crud.mixins, 如需其他自定义序列化方式，根据 pydantic 版本，采用不同方式定义

创建连接

AsyncDatabase

from sqlalchemy.ext.asyncio import AsyncEngine, create_async_engine

database_url = 'sqlite+aiosqlite:///test.db'
engine: AsyncEngine = create_async_engine(database_url)

Database

from sqlalchemy.engine import create_engine, Engine

database_url = 'sqlite+aiosqlite:///test.db'
engine: Engine = create_engine(database_url)

注册

from fastapix.crud import SQLAlchemyCrud, EngineDatabase, DBSessionMiddleware

database = EngineDatabase(engine)

cate_router = SQLAlchemyCrud(Category, database).router_manager()

# 挂载中间件
app.add_middleware(database.asgi_middleware)
# or 
app.add_middleware(DBSessionMiddleware, db=database)
# 挂载路由
app.include_router(cate_router.create_object_router())
app.include_router(cate_router.read_object_router())
app.include_router(cate_router.update_object_router())
app.include_router(cate_router.delete_object_router())
