Errors
Admin handlers return Result<_, laterite_admin::AdminError>.
| Variant | Status | Page |
|---|---|---|
NotFound | 404 | Not found |
Forbidden | 403 | Forbidden |
Internal(_) | 500 | Something went wrong |
Map a domain error
async fn edit(state: &AdminState, id: &str) -> Result<Response, AdminError> {
let row = fetch(state, id)
.await? // CoreError::NotFound -> 404, DB error -> 500
.ok_or(AdminError::NotFound)?; // a missing row -> 404
Ok(render(view(row)))
}| From | To |
|---|---|
CoreError::NotFound | 404 |
CoreError::Forbidden, CoreError::Unauthorized | 403 |
AuthError | Through CoreError, the same mapping |
| A database error, a render failure, a panic | 500 |
An unmatched admin URL renders the 404 page.
Show the cause in development
[app]
debug = true # off by default
A 500 logs its cause through tracing::error! in every mode. With debug on,
the page shows it too.
Validation
A refused submission is not an AdminError: it answers 422 with the form
re-rendered. See Validation.
