from quart_db import QuartDB
app = Quart(__name__)
db = QuartDB(app, url="postgresql://user:pass@localhost:5432/db_name"))
@app.get("/<int:id>")
async def get_count(id: int):
async with db.connection() as connection:
result = await connection.fetch_val(
"SELECT COUNT(*) FROM tbl WHERE id = :id",
{"id": id},
)
return {"count": result}
@app.post("/")
async def set_with_transaction():
async with db.connection() as connection:
async with connection.transaction():
await db.execute("UPDATE tbl SET done = $1", [True])
...
return {}Parameters can be defined via positional $1 or keyword :id binds.
