feat(api): add Pages endpoints to the public v1 API - #9757
Conversation
Add token-authenticated CRUD for project pages under /api/v1/workspaces/<slug>/projects/<project_id>/pages/: - PageListCreateAPIEndpoint: paginated list (visible pages only: own pages + public pages of active project members) and create with labels, parent validation and external id conflict handling - PageDetailAPIEndpoint: retrieve, update (locked-page and access-owner checks) and delete (archived-only, owner or project admin), mirroring the internal app API semantics - PageSerializer/PageCreateSerializer/PageUpdateSerializer with label_ids and project_ids queryset annotations - OpenAPI documentation (page_docs decorator, PAGE_PK_PARAMETER, request/response examples) - Contract tests covering CRUD, visibility, permissions and validation

In `@apps/api/plane/api/serializers/page.py`:
- Line 28: Update the PrimaryKeyRelatedField used for page labels so its
queryset is restricted to labels belonging to the current project via
project_id, rather than Label.objects.all(). Ensure both create and update
validation reject labels from other projects before PageLabel records are
persisted.
In `@apps/api/plane/api/views/page.py`:
- Around line 291-296: Update the page lookup in the relevant update action to
use self.get_queryset(), preserving the existing primary-key, workspace,
project, and non-deleted filters so the owner-or-public visibility predicate is
applied before mutation. Add a regression test verifying an authenticated
project member cannot update another user’s private page and that the page
remains unchanged.
- Around line 89-90: Update both ArrayAgg aggregation sites in
apps/api/plane/api/views/page.py at lines 89-90 and 230-231 to filter project
IDs with Q(projects__id__isnull=False) instead of comparing the UUID field to
True; no other changes are needed.

…lity on update - PageCreateSerializer: restrict the labels queryset to the current project so labels from other projects can no longer be attached (IDOR, CWE-639) - PageDetailAPIEndpoint.patch: resolve the page through get_queryset() so the owner-or-public visibility rule applies before mutation; a project member can no longer update another user's private page (CWE-862) - ArrayAgg project_ids filter: compare with isnull=False instead of True to avoid UUID conversion errors

Description
The public token-authenticated v1 API (
/api/v1/) has no Pages endpoints — Pages exist only in the internal API (/api/), which requires browser session authentication, so API tokens cannot read or write project documentation. This blocks CI/automation and AI/agent integrations on self-hosted CE instances (see the linked issues for the community demand).This PR adds full project-page CRUD to the v1 API, mirroring the internal app API semantics:
GET/POST /api/v1/workspaces/<slug>/projects/<project_id>/pages/GET/PATCH/DELETE /api/v1/workspaces/<slug>/projects/<project_id>/pages/<page_id>/Behavior mirrors
plane/app/views/page/base.py:ProjectPagelink; supportslabels,parent(validated to exist in the same project), andexternal_id/external_sourcewith a409on conflict.400;accesscan only be changed by the page owner;labelsare replaced wholesale.400otherwise); only the owner or a project admin may delete (403otherwise); child pages are detached and favorite/recent-visit rows are cleaned up.Also adds OpenAPI documentation (
page_docsdecorator,PAGE_PK_PARAMETER, request/response examples) so the endpoints show up in the generated API schema, and contract tests covering CRUD, visibility, permissions, and validation.Type of Change
