Implements feature request: https://community.gladysassistant.com/t/possibilite-de-dupliquer-un-tableau-de-bord/10393

Description

A user asked on the forum to be able to duplicate a dashboard, the way scenes can already be duplicated. This PR mirrors the scene duplication design end to end for dashboards.

Server

  • New server/lib/dashboard/dashboard.duplicate.js, modelled on scene.duplicate:
    • the source dashboard is looked up with the same permission rule the existing dashboard getBySelector/update/updateOrder code uses (a dashboard I created, or a public one), and a NotFoundError is thrown otherwise;
    • the copy keeps the type and the boxes of the source dashboard (faithful copy of the widgets/content);
    • the copy gets a brand new unique selector built with slugify(name, true) (slug + 4 random characters), like scenes do;
    • the copy is created through dashboard.create for the user asking for it, so it is placed at the end of their dashboard list (position = highest position + 1);
    • visibility: a dashboard you own keeps its visibility, while a public dashboard belonging to another user is duplicated as a private dashboard, so duplicating never re-shares a second copy with the whole installation.
  • New route POST /api/v1/dashboard/:dashboard_selector/duplicate (authenticated) and its controller, returning 201 with the new dashboard.

Front

  • New "Duplicate" button in the dashboard edit page actions (next to Cancel / Delete / Save), which opens the new page /dashboard/:dashboardSelector/duplicate.
  • New front/src/routes/dashboard/duplicate-dashboard/ page, built like the scene duplication page: it loads the source dashboard, prefills the name with Copy of <name>, lets the user change it, calls the new endpoint and redirects to the edit page of the new dashboard. Name conflicts (409, dashboard names are unique) and unknown errors are displayed.
  • New i18n keys (duplicateDashboard.* and dashboard.editDashboardDuplicateButton) added to en.json, fr.json and de.json.

Tests

  • server/test/lib/dashboard/dashboard.duplicate.test.js: duplicating my dashboard (name, type, boxes, position, unique selector with random suffix), duplicating my own public dashboard (stays public), duplicating a public dashboard of another user (becomes private and belongs to me), unknown selector and private dashboard of another user (both not found).
  • server/test/controllers/dashboard/dashboard.controller.test.js: POST /api/v1/dashboard/:dashboard_selector/duplicate success (201) and 404 cases.
  • Patch coverage of the changed server files verified locally at 100 % (statements, branches, functions, lines).

Forum

Forum: https://community.gladysassistant.com/t/possibilite-de-dupliquer-un-tableau-de-bord/10393

Checklist

  • Server tests pass: new dashboard.duplicate lib and controller tests pass, and the full npm test suite shows no new failure (the only failures in my sandbox are pre-existing environment ones: gateway backup/restore shelling out to the sqlite3 CLI, Docker and network tests)
  • Coverage: c8 run on the changed server files reports 100 % on lib/dashboard/dashboard.duplicate.js and api/controllers/dashboard.controller.js
  • Linter and prettier pass on both front and server (npm run prettier, npm run prettier-check, npm run eslint)
  • npm run compare-translations passes and npm run build (front) succeeds
  • No undocumented breaking change (only additive: one new endpoint, one new front route)
  • Cypress not run in my environment (no browser binary). The existing dashboard specs under front/cypress/e2e/routes/dashboard/ were reviewed: they target the Save/Delete/Edit buttons by their own translation keys, which the new Duplicate button does not collide with.

Note: this pull request was opened by an automated Claude Code run. It needs a human review before merging.

Summary by CodeRabbit

  • New Features
    • Added the ability to duplicate dashboards from the dashboard editor.
    • Users can customize the copied dashboard’s name with validation and conflict feedback.
    • Public dashboards can be copied, while copies made from another owner’s dashboard are private by default.
    • Added localized duplication flows in English, French, and German.
  • Bug Fixes
    • Added handling for missing dashboards and duplication errors.

Dashboards can now be duplicated the same way scenes can:

- server: new `dashboard.duplicate` lib function, mirroring
  `scene.duplicate`. It copies the boxes and the type of the source
  dashboard, gets a new unique selector (slugify with random suffix) and
  is created for the user asking for it, at the end of their dashboard
  list. The source lookup follows the existing dashboard permission
  model (a dashboard I created or a public one). A public dashboard of
  another user is duplicated as a private dashboard, so a copy is never
  re-shared with the whole installation.
- server: `POST /api/v1/dashboard/:dashboard_selector/duplicate` route
  and controller.
- front: "Duplicate" button on the dashboard edit page, opening a new
  `/dashboard/:dashboardSelector/duplicate` page prefilled with
  "Copy of <name>", like the scene duplication page.
- i18n: new `duplicateDashboard` keys and
  `dashboard.editDashboardDuplicateButton` in en, fr and de.

📝 Walkthrough

Walkthrough

Adds dashboard duplication through an authenticated API and dashboard service. Adds a localized frontend form with validation and status handling. Adds an edit-dashboard action that opens the duplication route. Adds server tests for copied dashboards, visibility, ownership, selectors, and errors.

Changes

Dashboard duplication

Layer / File(s) Summary
Server duplication operation and API
server/lib/dashboard/..., server/api/..., server/test/...
The server duplicates owned or public dashboards, applies visibility rules, creates a slugified selector, and returns the copied dashboard. Tests cover successful copies, visibility, ownership, selectors, and not-found cases.
Frontend duplication route and form
front/src/routes/dashboard/duplicate-dashboard/*, front/src/components/app.jsx, front/src/config/i18n/*
The frontend loads the source dashboard, suggests and validates a name, submits the duplication request, displays errors, and navigates after success. English, German, and French translations support the form.
Edit dashboard entry point
front/src/routes/dashboard/edit-dashboard/*
The edit actions footer adds a duplicate button that opens the dashboard duplication route.

Poem

A rabbit copied a dashboard bright,
With boxes aligned and names just right.
A slug was carved, a route was spun,
Public boards stayed safe for everyone.
“Hop to the editor!” sang the hare—
New copies now appear there.

Stale comment

Approved. This is a clean, additive dashboard duplicate that mirrors scene.duplicate end to end.

Server: source lookup uses the same own-or-public rule as getBySelector/update; the copy keeps type and boxes; the selector is slugify(name, true); dashboard.create places it at the end of the requester's list. Copying another user's public dashboard as a private dashboard owned by the requester is the right security default and is tested (unknown selector and someone else's private dashboard both 404).

Front: Duplicate on the edit page opens a copy-of-name form, handles 409/unknown errors, and redirects to the new dashboard's edit page. i18n keys are present in en/fr/de. No DEVICE_FEATURE_* changes, no schema/migration.

CI is green (front test/build, server test+lint, Cypress, Docker, codecov patch + project).

Not risk:high. Not needs:human-review — this follows an existing Gladys pattern rather than a product-philosophy call.

Non-blocking notes inline: unsaved edit-page state is discarded on Duplicate, and duplicating your own public dashboard stays public (immediately visible to every user). Other residuals: CodeRabbit's stale setState re-validate matches duplicate-scene; no Cypress for the new flow (existing Dashboard.cy.js still passes); missing name would 500 via slugify the same way scene duplicate does; if #2902 merges later, duplicate will need to copy appearance/assets.

Comment thread server/lib/dashboard/dashboard.duplicate.js
- front: validate the name being typed in the duplicate dashboard form
  instead of the value still in the state. `setState` is asynchronous, so
  `checkErrors` was reading the previous name and the "name is required"
  error stayed visible one input event too long.
- front: state on the duplicate page that the copy is made from the last
  saved version of the dashboard. The Duplicate button sits next to Save
  in the editor and navigates away, so unsaved boxes or name changes are
  not part of the copy.

Re-reviewed after ae47f44. This remains a clean, additive dashboard duplicate that mirrors scene.duplicate end to end, and the follow-up addresses the prior review notes.

Follow-up: name validation now checks the typed value (e.target.value) so a corrected name clears the error on the same input event. The duplicate page documents that the copy is the last saved version (duplicateDashboard.savedVersionInfo in en/fr/de), which is the right scope given the editor has no dirty-tracking. Keeping your own public dashboard public is accepted as a faithful copy / scene-parity choice.

Server: source lookup uses the same own-or-public rule as getBySelector/update; the copy keeps type and boxes; the selector is slugify(name, true); dashboard.create places it at the end of the requester's list. Copying another user's public dashboard as a private dashboard owned by the requester is the right security default and is tested (unknown selector and someone else's private dashboard both 404).

Front: Duplicate on the edit page opens a copy-of-name form, handles 409/unknown errors, and redirects to the new dashboard's edit page. i18n keys are present in en/fr/de. No DEVICE_FEATURE_* changes, no schema/migration.

CI is green on ae47f44 (front test/build, server test+lint, Cypress, Docker, codecov patch + project).

Not risk:high. Not needs:human-review — this follows an existing Gladys pattern rather than a product-philosophy call. needs:cursor-review was not present.
