Calendars API (calendars)

The calendars module serves working calendars, shifts, calendar templates, calendar exceptions, holiday import, a calendar preview, the group calendar, and owner calendars. All 23 endpoints sit under /api/v1/calendars. For business meaning see the Calendars module page.

Group facts¶

Endpoint summary¶

One row per sub-module folder. The router prefix is added to the base path.

Working calendars endpoints¶

One router with no prefix of its own: shifts, templates, calendars, exceptions per calendar, holiday countries and import, a preview, the group calendar, and for-owner to ensure an owner's calendar.

Error codes¶

The table lists the error codes that code under src/cluster_erp/modules/calendars/ raises, found by a syntax-tree scan for AppError(...), the factories in src/cluster_erp/core/errors.py (not_found, conflict, protected, permission_denied, privilege_escalation, check_version), and HTTPException(...). A status of 400 is the AppError default (src/cluster_erp/core/errors.py:23). Guard errors (401, 403), the entitlement codes, and validation errors (422) apply to every route and are listed on Errors.

Events emitted¶

The table lists the contract classes that code under src/cluster_erp/modules/calendars/ passes directly to EventBus.emit, found by a syntax-tree scan. Events built in a variable first are not counted. The contracts are described in Contracts reference.
