Comment

from fastapi import FastAPI, Depends, HTTPException
from sqlalchemy.ext.asyncio import AsyncSession, create_async_engine
from sqlalchemy.orm import sessionmaker
from sqlmodel import SQLModel, Field, create_engine

# PostgreSQL connection URL
DATABASE_URL = "postgresql+asyncpg://user:password@localhost/dbname"

# Create the async engine
async_engine = create_async_engine(DATABASE_URL)

# Create async session class
async_session = sessionmaker(
    autocommit=False, autoflush=False, bind=async_engine, class_=AsyncSession
)

# Dependency to get async session
async def get_session():
    async with async_session() as session:
        yield session

# Example model
class Item(SQLModel, table=True):
    id: int = Field(default=None, primary_key=True)
    name: str
    description: str

app = FastAPI()

# Route to create a new item
@app.post("/items/")
async def create_item(item: Item, session: AsyncSession = Depends(get_session)):
    async with session.begin():
        session.add(item)
        await session.commit()
        await session.refresh(item)
        return item
