Docs: <Is it possible to use handler deps in guards/middleware?>

Summary

Hello, what to do if I'd like to perform some db checks on private endpoint, so I want to get my db/mq dependency to check if user is not blocked? It seems to have a dependency dict, but it is unclear, how do I extract dependency at this point

no it's not currently possible, #1129

check this if you are using fullstack https://discord.com/channels/919193495116337154/1343345321232830656/1343345322214035456

now you can easily use the connection parameter of your guard function and get the db from the state (provided you configure it this way but you should be able to adapt easily).

I'm doing this for instance, interesting line is pool = cast("BuildPgPool", connection.app.state.get("dbpool")):

async def check_order_id_seller(
    connection: ASGIConnection,
    _: BaseRouteHandler,
) -> None:
    # checks that the order id belongs to the seller !
    query = """select u.username from orders o
    left join products p on p.products_uuid = o.products_uuid_products
    left join users u on p.users_uuid_users = u.users_uuid
    where o.orders_uuid=:orders_uuid"""
    pool = cast("BuildPgPool", connection.app.state.get("dbpool"))
    async with pool.acquire() as conn:
        response = await conn.fetchrow_b(
            query, orders_uuid=connection.path_params["orders_uuid"]
        )
