Timetables Backend

Purpose

timetables is a named, dated schedule (a campus/academic-year timetable with a draft/active/ archived status) that owns a set of timetable_periods. It is a generic-CRUD slice assembled from the shared factories.

Slice Files (by layer)

  • Route: src/routes/timetables.tscreateCrudRouter(controller, { permission: 'timetables' }).
  • Controller: src/api/controllers/timetables.controller.tscreateCrudController(service, { csvFields }).
  • Service (BLL): src/services/timetables.tscreateCrudService(DbApi, { notFoundCode: 'timetablesNotFound' }).
  • Repository (DAL): src/db/api/timetables.ts (TimetablesDBApi) — entity-specific create/bulkImport/update/findBy/findAll; remove/deleteByIds/findAllAutocomplete delegate to db/api/shared/repository.ts.
  • Model: src/db/models/timetables.ts.
  • Shared used: CRUD factories (services/shared/crud-service.ts, api/controllers/shared/crud-controller.ts, api/http/crud-router.ts), repository helpers (db/api/shared/repository.ts), shared/constants/pagination.ts (resolvePagination), db/utils.ts (Utils.uuid/Utils.ilike), shared/constants/database.ts (BULK_IMPORT_TIMESTAMP_STEP_MS).

API

The standard generic-CRUD surface (all under /api/timetables, JWT + ${METHOD}_TIMETABLES permission, all 200) — see backend-architecture.md for the shared 9-endpoint contract:

  • POST / — body { data }, returns true.
  • POST /bulk-import — multipart CSV file, returns true.
  • PUT /:id — body { data, id } (the service reads the id from the body), returns true.
  • DELETE /:id — returns true.
  • POST /deleteByIds — body { data: string[] }, returns true.
  • GET / — query filters, returns { rows, count }; ?filetype=csv streams a CSV of csvFields.
  • GET /count — returns { rows: [], count }.
  • GET /autocomplete?query&limit&offset, returns [{ id, label }] where label is name.
  • GET /:id — returns the record with eager associations (see Data Contract).

csvFields: id, name, effective_from, effective_to.

Access Rules

  • JWT required; the whole router is guarded by checkCrudPermissions('timetables'), deriving READ_TIMETABLES / CREATE_TIMETABLES / UPDATE_TIMETABLES / DELETE_TIMETABLES per HTTP method.
  • Access is granted by role permission or per-user custom_permissions (see permissions.md).

Tenant Scope

  • findAll scopes where.organizationId to currentUser.organizationId; a globalAccess role clears the org filter (sees all tenants).
  • create assigns the organization from currentUser.organizationId; update only reassigns organization for globalAccess users (otherwise it stays the caller's org).

Data Contract

Model columns (paranoid, soft-delete via deletedAt):

  • id (UUID PK).
  • name — TEXT.
  • effective_from, effective_to — DATE.
  • status — ENUM draft | active | archived.
  • importHash (STRING(255), unique), academic_yearId, campusId, organizationId, createdById, updatedById, timestamps (all UUID FKs nullable).

Associations: belongsTo organization, campus, academic_year (academic_years), createdBy/updatedBy (users); hasMany timetable_periods as timetable_periods_timetable. findBy/GET /:id eager-load timetable_periods_timetable, organization, campus, and academic_year in a single Promise.all.

List filters (TimetablesFilter): id, name (iLike), effective_fromRange, effective_toRange, status, campus (id or name, |-separated), academic_year (id or name), organization, createdAtRange, plus a calendar overlap pair calendarStart + calendarEnd (matches rows whose effective_from or effective_to falls between the two), and field/sort ordering and limit/page pagination.

Behavior / Notes

  • create/bulkImport/update set associations via the Sequelize set* mixins (no file relations on this entity).
  • bulkImport offsets createdAt per row by BULK_IMPORT_TIMESTAMP_STEP_MS to preserve order.
  • List pagination uses the shared resolvePagination defaults (page size 10, capped at 100).
  • Note: TimetablesFilter accepts an active flag the model has no column for; it is applied to where.active but, with no such column, is currently inert (kept for source accuracy).
