Attribute Macro action 

#[action]

Attribute macro for POST-style action handlers that mutate state and redirect.

Transforms an async function returning ActionResult into a Response-returning handler. On Ok(()) emits a 303 redirect to redirect_to; on Err(ActionError) emits a 303 redirect to redirect_to (or err.redirect_override if set and same-origin) with a flash payload and back-compat ?error=...&msg=... query parameters.

Required attributes

• redirect_to = "<path>" — the default 303 target on success.

Optional attributes

• method = "<METHOD>" — HTTP method hint (default "POST").

Example

use ferro::{action, ActionError, ActionResult, Request};

#[action(redirect_to = "/dashboard/pagine")]
pub async fn publish_by_id(req: Request) -> ActionResult {
    let id: i64 = req.param("id")?.parse()?;
    publish_page(id).await?;
    Ok(())
}
