Tables tab: row action pipeline, publish and unpublish from the row

[jh-RLI]

Closes #2561. Slice 9 of #2551.

What it does

Every row of the tables tab gets its ⋯ menu, and every action on Tables goes through one service.

• The table action service is in api/services/table_actions.py.
  • preflight(user, action, names, params) says what would run, what is left out and why (grouped, with the text the user sees), and the consequences the dialog must state.
  • execute(user, action, names, params, via=) re-checks every named Table under a row lock. If any Table is no longer allowed, it refuses the whole request (ActionRefused) and writes nothing. Otherwise it writes every Table in one transaction.
  • Log lines go to oeplatform.table_actions, one per Table, after commit: table_action table=… action=… by=<pk> via=dashboard batch=<id>|-, plus topic=/embargo= on publish.
• The dashboard endpoint is profile/<user_id>/tables/actions/<action> (TableActionView), behind the owner rule. A row action is a batch of one: the endpoint takes repeated table parameters.
  • GET returns the dialog.
  • POST succeeds with 204 and HX-Trigger: tables-changed carrying {message, focus}.
  • POST refused answers 409 with the dialog run again ("Nothing was changed: …") and HX-Trigger: tables-refused.
  • An unusable parameter answers 400 with the error beside its field.
• The ⋯ menu has Edit metadata and Upload data (links to the existing pages), then Publish… or Unpublish.
  • An action above the user's role stays in the menu, marked aria-disabled="true", with the reason as visible text and a click guard. It does not use Bootstrap's .disabled, so the keyboard still reaches it (checked in Chrome).
  • Manage access, the Dataset entries and Delete are absent until their tickets.
• Publish offers the 13 real Topics and an embargo of none, 6 months or 1 year. The service refuses the draft pseudo-topic. It leaves out Tables below Table admin, Tables already published, and Tables that fail the gate.
• Unpublish asks for a plain confirmation: the Table "will no longer be listed under its topics". The dialog names other people's Datasets that will then hold a draft member.
• After an action:
  • The results region re-fetches itself, because it declares hx-trigger="tables-changed from:body" with its own page.url.
  • That request names the region as its trigger, so the view answers HX-Replace-Url instead of HX-Push-Url, and an action adds no history entry.
  • The message names a changed Table that the current filter no longer shows. The server reads this off HX-Current-URL through Listing.matching.
  • Focus goes to the row's ⋯, or to #tables-heading if the row is gone. A cancel returns focus to the ⋯.
• Toasts: success is polite and leaves after about 5 s. Refusals and failures are assertive and stay until dismissed. One htmx:responseError handler covers the rest: a 401 says "You have been logged out." with a login link carrying next; any other error, and an unreachable server, say "the change may not have been made; reload".

Decisions worth a look

• The service lives in api/services/, beside the dataset service, because API: single-table publish, unpublish and delete go through the table action service #2569 moves the API onto it. It imports PUBLISH_GATE and visible_datasets from login/tables_tab.py. The reverse import would be a cycle, so the menu reads the role gates (ROLE_GATES) from the view's context instead. The menu costs no query: the page stays at 7.
• The service's role rule mirrors myuser.get_table_permission_level, the rule the API decorators read. It includes platform admins and members of an admin Organization. That keeps API: single-table publish, unpublish and delete go through the table action service #2569 from changing who may do what through the API. Consequence: the row's level (from Tables tab: Publishable, Review, Datasets and Topics columns #2554) ignores those two cases, so a platform admin who holds only Data editor directly sees Publish disabled in the menu, although the service would allow it. This is an edge case, and I left it alone rather than change Tables tab: Publishable, Review, Datasets and Topics columns #2554's Access cell.
• The gate is run live in the preflight for now. Once Store the Publish gate result: Publishable filter and sort #2560 stores the result, the preflight should read the stored flag (spec), and publishing keeps validating live. One function (_gate_reason) is the place to change.
• No ceiling yet. Preflight.ceiling is None, because rows send one name and the ceilings for publish and unpublish are measured in Tables tab: selection, bulk bar and bulk publish/unpublish #2564.
• The re-check holds a row lock (select_for_update on the named Tables), so two concurrent publishes of one draft cannot both pass the check and give it a second Topic.
• Publish reuses api.actions.move_publish inside the transaction. Its own live license check raising APIError rolls back the whole batch and becomes a refusal.

Tests

• 34 tests in login/tests/test_table_actions.py, all through HTTP. They cover the menu gates (direct and through an Organization), the left-out groups, the real Topics only, other people's Datasets, nothing written by a preflight, the owner rule, publish with and without embargo, each unusable parameter, refused-whole (role lost, already published, gate failing), batch atomicity (the second write fails, the first is rolled back), the "not shown under the current filter" note, the log lines (batch id shared, - for one Table, none on refusal), HX-Replace-Url vs HX-Push-Url, and the re-fetched state.
• 17 new vitest cases in tables_tab.test.js: the dialog opens on fill, 400/409 swap into it, the disabled click is swallowed, toasts (polite or assertive, timeout, text only), the 401 login link, 5xx and network errors, and focus to the ⋯, the heading, the opening row, or back after a cancel.
• login + base.tests.test_views: 273 green. Full suite: green except LightImportTest, the known artefact of the isolated-settings trick. vitest: 64 green. The OpenAPI drift guard is green.

Checked in a browser

Headless Chrome, a seeded throwaway database, the sidebar shown, the branch's own static files.

• A Data editor's Publish… shows "Only Table admins can publish". Clicking it keeps the menu open and opens no dialog. ArrowDown reaches it.
• Publishing under ?status=draft:
  • a confirm without a Topic shows "Choose a topic." in the still-open dialog;
  • with a Topic and 6 months, the dialog closes and the toast reads Published "Ready wind data" under climate, embargoed for 6 months. It is not shown under the current filter.;
  • focus lands on the heading and the row is gone;
  • the address and history.length are unchanged;
  • the toast is gone after 5 s.
• Unpublish names strangers_dataset (browser_stranger). Afterwards focus is on that row's ⋯ and the status cell reads Draft.
• Cancel (Escape) returns focus to the ⋯.
• A role lowered while the dialog was open gives a 409: "Nothing was changed: Only Table admins can publish ("b_ready_two")." appears in the still-open dialog and as an assertive toast.
• Logged out, a menu entry gives the toast "You have been logged out. Log in again" with ?next= pointing at the view. Offline gives "The server could not be reached…".
• The browser checks found two things, both fixed in this branch:
  • htmx:afterSwap carries the target in detail.elt; the requesting element is in requestConfig.elt. The test helper had mimicked the wrong shape.
  • A sticky cell is its own stacking context, so the later rows' ⋯ painted over an open menu.
• No JS errors in the console. The only console lines are the browser's own resource messages for the deliberate 400 and 409.

eslint was skipped at commit (SKIP=eslint). Its --fix would have reformatted the 19 findings already in tables_tab.js and its test; the new lines follow the file's existing style.
