Feature/checklist items - #9801
Conversation
Introduces TIssueChecklistItem and adds "checklist" to TWorkItemWidgets so downstream store/UI code can reference the new work item widget. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Maps checklist item statuses to state groups for reuse of StateGroupIcon/STATE_GROUPS presentation, without binding the checklist model to the StateGroup workflow concept. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
A minimal checklist step (name + status) scoped to an issue, with no assignee or dates by design — a step needing those belongs on a sub-issue instead. completed_at/completed_by are synced from status on save, mirroring Issue's own completion tracking; only DONE counts as completion, SKIPPED deliberately does not. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Adds IssueChecklistItemSerializer and IssueChecklistItemViewSet, wired up under /workspaces/<slug>/projects/<id>/issues/<id>/checklist-items/ for list/create/retrieve/partial_update/destroy. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Logs create/rename/status-change/delete as issue activity entries. A drag-reorder PATCH only ever carries sort_order and stays silent per spec, since reordering isn't a change worth surfacing in the activity feed. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Covers CRUD, sort order, status transitions, activity logging, cross-project scoping, and guest write access denial. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Adds IssueService methods for the checklist-items endpoints and a IssueChecklistStore following the pattern of the existing link/ attachment stores. Fetching is gated to ISSUES service type only, since epic child routes live in the EE backend and diverge from the OSS issue routes. Also fixes two pre-existing oxlint warnings (unreturned promise, shadowed `action` param) in issue.store.ts/root.store.ts that otherwise block lint-staged on these files. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Adds the checklist item list/add/status-dropdown components and wires them into the issue detail widget row (action button + collapsible), following the pattern of the existing links/ attachments widgets. Unlike those, a checklist with zero items still renders while an item is being added, since there's no modal-based "add" flow for it. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Adds IssueChecklistItemActivity and wires it into IssueActivityItem for the "checklist_item" and "checklist_item_status" activity fields emitted by the backend. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Adds checklist.* status labels and issue.add.checklist_item to common.json/work-item.json for every supported locale. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Replaces the string-literal union with EChecklistItemStatus,
matching the EIssueServiceType/EPageAccess convention used
elsewhere, and updates all consumers off the old string literals
("to_do", "done", "skipped") onto the enum members.

DRF's test client exposes response.data as the pre-render internal representation, where UUID fields come back as uuid.UUID objects rather than JSON strings. Several assertions compared a str id against a set of raw UUID objects (or vice versa) and failed despite the underlying behavior being correct. Compare both sides as str consistently, and use IssueChecklistItem.all_objects (not the soft-delete-excluding default manager) to look up a row after deleting it. All 33 checklist contract tests pass. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

Pull request overview
Adds first-class checklist items to work items (issues), providing a lightweight progress-tracking mechanism between “inline markdown checkboxes” and “full sub-issues”, with backend persistence + activity logging and a new frontend widget (including drag-and-drop ordering and progress display).
Changes:
- Backend: introduce
IssueChecklistItemmodel + migration, scoped viewset routes, serializer validation/readonly fields, and activity-task handlers for checklist activity feed entries. - Frontend: add MobX checklist sub-store, issue service endpoints, checklist widget UI (list/add/edit/status/dropdown/reorder), and activity feed rendering for checklist activities.
- i18n/types/constants: add checklist types/constants and translate new checklist strings across locales.

Fixed in cc4d4c1 — the dropdown now falls back to the first known status (to_do) when value isn't in CHECKLIST_ITEM_STATUS_MAP, so it degrades instead of crashing on current.stateGroup.

Fixed in cc4d4c1 — create and update now show success toasts using the existing checklist.toasts.created.* / checklist.toasts.updated.* i18n keys, matching remove()'s behavior and the code comment's documented intent.

In `@apps/web/core/components/issues/issue-detail-widgets/checklist/helper.tsx`:
- Line 48: Make the checklist mutation helpers consistently resolve after
displaying the error toast: remove the rethrows from create at
apps/web/core/components/issues/issue-detail-widgets/checklist/helper.tsx:48,
update at the same file:61, and setStatus at the same file:74, matching reorder
and remove. No direct changes are needed at checklist-add-item.tsx:52-60 or
checklist-item.tsx:120 and :134 because the root-cause fix eliminates their
unhandled rejections.
In `@apps/web/core/components/issues/issue-detail/checklist/checklist-item.tsx`:
- Line 180: Update the delete button’s conditional class in the checklist item
so its hidden state is overridden by the row’s group-focus-within state,
revealing it when the text input or another row control receives focus. Preserve
the existing hover behavior and do not add focus-visible handling.
In
`@apps/web/core/components/issues/issue-detail/issue-activity/activity/actions/checklist-item.tsx`:
- Around line 46-73: Update the checklist activity rendering around the created,
deleted, renamed, and status-change branches to use the existing translation
function instead of hardcoded English phrases. Add or reuse translation keys for
all four templates, interpolating checklist item names and old/new status values
while preserving the existing statusLabel behavior and styling.
In `@apps/web/core/services/issue/issue.service.ts`:
- Line 350: Update the error handling at each affected throw site in the issue
service to throw the HTTP response when available, but fall back to the original
error when no response exists. Apply this consistently to all four handlers,
preserving the existing response-based behavior while ensuring pre-response
request failures retain their cause.
In `@apps/web/core/store/issue/issue-details/checklist.store.ts`:
- Line 155: Serialize checklist reconciliation in the issue/checklist store by
tracking current revisions per issue and checklist item. Guard the fetch
application at addChecklistItems, PATCH success handling, and PATCH rollback
handling so stale responses or failures cannot overwrite newer state; invalidate
pending fetch revisions when create, update, or delete operations succeed.

- Guard ChecklistStatusDropdown against an unrecognized status value instead of crashing on an undefined stateGroup lookup - Show success toasts on checklist item create/update, matching the documented intent and the existing remove() behavior - Attach .catch() at the fire-and-forget call sites for create/update/ setStatus so a failed mutation no longer produces an unhandled promise rejection, while preserving the input-not-cleared-on-failure and optimistic-rollback behavior those throws exist for - Reveal the checklist item delete button on keyboard focus (group-focus-within), not just mouse hover Addresses automated review comments from Copilot and CodeRabbit on makeplane#9801. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Add per-issue and per-item revision counters so a slower, now-stale fetch/update response can no longer overwrite newer local state: - fetchChecklistItems captures the issue's revision before the GET and only applies the response if no create/update/delete has landed since, so an in-flight list fetch can't stomp a completed mutation. - updateChecklistItem claims a new revision per call; its success reconciliation and its error rollback are both skipped once a later call for the same item has superseded it, so two overlapping updates (e.g. rapid status toggles) can no longer resolve out of order and clobber each other's result. - create/update/remove bump the issue revision on success so any checklist mutation invalidates a concurrently in-flight fetch. Addresses the CodeRabbit review finding on makeplane#9801 (checklist.store.ts state-reconciliation race). Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Fixes #9687
Description
Adds a lightweight checklist to work items, sitting between an in-description checkbox (no structure, no audit trail) and a full sub-issue (state machine, sequence ID, board presence — heavyweight for tracking small steps).
Each work item can carry a flat, ordered list of checklist items. Each item has a name and a four-value status (
to_do/in_progress/skipped/done), rendered with the sameStateGroupIcon/STATE_GROUPScolors used elsewhere in the app. Progress isdone / (total − skipped)— skipped items leave the denominator, mirroring howcalculateCycleProgressalready excludes cancelled issues, so a checklist where everything is done-or-skipped reads as 100% complete rather than stuck below it.Backend:
IssueChecklistItemmodel (ProjectBaseModel+ChangeTrackerMixin), migration, serializer with an explicit read-only field list (notfields = "__all__", socompleted_at/completed_bycan't be client-set), aProjectEntityPermission-guarded viewset scoped on workspace+project+issue together (the same cross-project IDOR class documented insub_issue.py), activity logging split intochecklist_item(add/rename/delete) andchecklist_item_status(status changes) fields, and float-midpoint ordering matchingIssue.sort_order's convention. Deliberately nonotification=Trueon the activity dispatch — unlikeIssueLinkViewSet, a status change must not email every subscriber.Frontend: a new widget slice (
issue-detail-widgets/checklist/) mounted first in the collapsibles list and the action-button row, a MobX sub-store wired intoIssueDetailalongside the existing sub-stores, drag-and-drop reordering (@atlaskit/pragmatic-drag-and-drop, following the flat-listattachClosestEdgepattern fromproject-states/state-item.tsxrather than the tree-aware label DnD HOC, since items have no nesting), an inline always-mounted add input (no modal — the whole point of this feature is that adding a step costs typing and Enter, not a dialog), and an activity-feed renderer for both field types.Scoped out of v1, deliberately: no assignee/due-date on items (would recreate the sub-issue overhead this is meant to avoid), no denormalized progress columns on
Issue(would need correlated subqueries across ~21 annotation sites for a feature that's detail-view-only in this cut), no epic support (epic child routes live in a separate EE backend and diverge from the OSS issue routes — opening an epic must not 404 against/epics/<id>/checklist-items/, so every mount point and fetch call is explicitly gated onEIssueServiceType.ISSUES), no public v1 API, no webhooks.Also includes translations for every new string across all 19 non-English locales (
pnpm --filter @plane/i18n run sync:checkreports 100% coverage).Type of Change
Screenshots and Media (if applicable)
Not included — verification was done via the backend contract suite and static frontend checks; no interactive browser session was available in this environment.
Test Scenarios
Backend:
Covers: cross-project scoping (404, never 403 or leaked data), guest read-only enforcement, CRUD + name validation, status transitions (critically:
skippedsets neithercompleted_atnorcompleted_by— the assumption most likely to be miscoded carrying over boolean-era habits), sort-order append/midpoint-reorder/tie-breaking, and activity logging including a regression guard confirming no notification is ever dispatched.Frontend:
Not run: a manual browser walkthrough (no interactive session available here). Worth doing before merge — particularly the optimistic-update rollback on a failed PATCH, the "all items skipped" ring state, and confirming the peek-overview and full-page detail views render identically.
