Add V127 (sub-project links) + V128 (project assignee) migrations#580
Merged
Conversation
Core schema support for the phoenix_kit_projects nested-sub-projects + project-assignee feature. Renumbered from V126/V127 → V127/V128 after rebasing onto main, which took V126 for standalone notifications (BeamLabEU#579). Bumps @current_version 126 → 128. V127 — Sub-projects as tasks: adds child_project_uuid to phoenix_kit_project_assignments (ON DELETE RESTRICT) so an assignment can embed a child project instead of a task; task_uuid-XOR-child CHECK; partial unique index (one parent per child); drops task_uuid NOT NULL. down/1 deletes the child-link rows before restoring NOT NULL. V128 — Assignee on projects: adds assigned_team/department/person_uuid to phoenix_kit_projects (ON DELETE SET NULL) with a single-assignee CHECK + partial indexes. A sub-project is a project, so this covers it too.

Renumbered V126/V127 → V127/V128 after rebasing onto main, which took V126 for standalone notifications (#579).
Core schema support for the
phoenix_kit_projectsnested-sub-projects + project-assignee feature. Two versioned migrations; bumps@current_version126 → 128.V127 — Sub-projects as tasks
Adds
child_project_uuidtophoenix_kit_project_assignmentsso an assignment can embed a child project instead of a task template:phoenix_kit_projects(uuid)ON DELETE RESTRICT (recursive teardown is orchestrated explicitly in the context, not via cascade).task_uuidNOT NULL; adds aCHECK ((task_uuid IS NOT NULL) <> (child_project_uuid IS NOT NULL))XOR.child_project_uuid(a project is a child of at most one parent) + a plain lookup index.down/1deletes the child-link rows (which havetask_uuid IS NULL) before restoringtask_uuid NOT NULL, so rollback can't fail on those rows.V128 — Assignee on projects (and sub-projects)
Adds
assigned_team_uuid/assigned_department_uuid/assigned_person_uuidtophoenix_kit_projects(ON DELETE SET NULL), a single-assigneeCHECK (num_nonnulls(...) <= 1), and partial indexes. Since a sub-project is a project, this one column set also covers assigning a sub-project.Both migrations are idempotent (existence-guarded), prefix-aware, and set the
COMMENT ON TABLE phoenix_kitversion marker correctly in both directions (126↔125, 127↔126).Consumed by the
phoenix_kit_projectssub-projects PR (which pins the core release that ships these).
