How to use delete operation with async orm?

We used to use synchronous ORM operations using code below:

obj = session.query(User).get(id)
session.delete(obj)
session.commit()

How should we use delete operation in asynchronous ORM?

Versions:

• Python: 3.8.5
• SQLAlchemy: 1.4

I know it’s outdated, but I’ve met same problem and figured out, how to fix it.

@app.get("/db/del/{index}", response_model=list[Weather]) async def delete_row(index: int, session: AsyncSession = Depends(get_session)):

Inside function: row = await session.execute(select(Weather).where(Weather.id == index)) row = row.scalar_one() await session.delete(row) await session.commit()

Idk if it is right, but it works, at least for me.

Hi,

The documentation is probably the best place to start: https://docs.sqlalchemy.org/en/14/orm/extensions/asyncio.html
