//! The request handlers behind the five table-definition pages.
|
|
//!
|
|
//! Each page has a GET that renders it and, except for the read-only history,
|
|
//! a POST per write it offers. A write answers with its own page's body,
|
|
//! re-read from the backend, so what the user sees after a change is the
|
|
//! definition as it now is rather than the form they submitted. A refused
|
|
//! write answers the same way but with 422 and the backend's own message,
|
|
//! which `ui/base.html` swaps in because a 4xx still carries the explanation.
|
|
//!
|
|
//! Two exceptions. Staging a column changes nothing on the server, so those
|
|
//! interactions swap only the column panel. And a successful delete leaves no
|
|
//! page to return to — the table it was about is gone — so it redirects to the
|
|
//! admin panel instead.
