# Academic Periods CRUD Build Plan
|
|
|
|
## Goal
|
|
|
|
Add full academic period lifecycle management to the settings page and backend, including safe archive and hard-delete behavior, recurrence spillover blockers, and a UI restructuring where `Perioden` becomes the first sub-tab under `Akademischer Kalender`.
|
|
|
|
## Frontend Design Rules
|
|
|
|
All UI implementation for this build must follow the project-wide frontend design rules:
|
|
|
|
→ **[FRONTEND_DESIGN_RULES.md](FRONTEND_DESIGN_RULES.md)**
|
|
|
|
Key points relevant to this build:
|
|
- Syncfusion Material3 components are the default for every UI element
|
|
- Use `DialogComponent` for all confirmations — never `window.confirm()`
|
|
- Follow the established card structure, button variants, badge colors, and tab patterns
|
|
- German strings only in all user-facing text
|
|
- No Tailwind classes
|
|
|
|
## Agreed Rules
|
|
|
|
### Permissions
|
|
|
|
- Create: admin or higher
|
|
- Edit: admin or higher
|
|
- Archive: admin or higher
|
|
- Restore: admin or higher
|
|
- Hard delete: admin or higher
|
|
- Activate: admin or higher
|
|
- Editors do not activate periods by default because activation changes global system state
|
|
|
|
### Lifecycle
|
|
|
|
- Active: exactly one period at a time
|
|
- Inactive: saved period, not currently active
|
|
- Archived: retired period, hidden from normal operational selection
|
|
- Deleted: physically removed only when delete preconditions are satisfied
|
|
|
|
### Validation
|
|
|
|
- `name` is required, trimmed, and unique among non-archived periods
|
|
- `startDate` must be less than or equal to `endDate`
|
|
- `periodType` must be one of `schuljahr`, `semester`, `trimester`
|
|
- Overlaps are disallowed within the same `periodType`
|
|
- Overlaps across different `periodType` values are allowed
|
|
- Exactly one period may be active at a time
|
|
|
|
### Archive Rules
|
|
|
|
- Active periods cannot be archived
|
|
- A period cannot be archived if it still has operational dependencies
|
|
- Operational dependencies include recurring master events assigned to that period that still generate current or future occurrences
|
|
|
|
### Restore Rules
|
|
|
|
- Archived periods can be restored by admin or higher
|
|
- Restored periods return as inactive by default
|
|
|
|
### Hard Delete Rules
|
|
|
|
- Only archived and inactive periods can be hard-deleted
|
|
- Hard delete is blocked if linked events exist
|
|
- Hard delete is blocked if linked media exist
|
|
- Hard delete is blocked if recurring master events assigned to the period still have current or future scheduling relevance
|
|
|
|
### Recurrence Spillover Rule
|
|
|
|
- If a recurring master event belongs to an older period but still creates occurrences in the current or future timeframe, that older period is not eligible for archive or hard delete
|
|
- Admin must resolve the recurrence by ending, splitting, or reassigning the series before the period can be retired or deleted
|
|
|
|
## Build-Oriented Task Plan
|
|
|
|
### Phase 1: Lock The Contract
|
|
|
|
Files:
|
|
|
|
- `server/routes/academic_periods.py`
|
|
- `models/models.py`
|
|
- `dashboard/src/settings.tsx`
|
|
|
|
Work:
|
|
|
|
- Freeze lifecycle rules, validation rules, and blocker rules
|
|
- Freeze the settings tab order so `Perioden` comes before `Import & Liste`
|
|
- Confirm response shape for new endpoints
|
|
|
|
Deliverable:
|
|
|
|
- Stable implementation contract for backend and frontend work
|
|
|
|
### Phase 2: Extend The Data Model
|
|
|
|
Files:
|
|
|
|
- `models/models.py`
|
|
|
|
Work:
|
|
|
|
- Add archive lifecycle fields to academic periods
|
|
- Recommended fields: `is_archived`, `archived_at`, `archived_by`
|
|
|
|
Deliverable:
|
|
|
|
- Academic periods can be retired safely and restored later
|
|
|
|
### Phase 3: Add The Database Migration
|
|
|
|
Files:
|
|
|
|
- `server/alembic.ini`

|
- `server/initialize_database.py`
|
|
|
|
Work:
|
|
|
|
- Add Alembic migration for archive-related fields and any supporting indexes
|
|
- Ensure existing periods default to non-archived
|
|
|
|
Deliverable:
|
|
|
|
- Schema upgrade path for current installations
|
|
|
|
### Phase 4: Expand The Backend API
|
|
|
|
Files:
|
|
|
|
- `server/routes/academic_periods.py`
|
|
|
|
Work:
|
|
|
|
- Implement full lifecycle endpoints:

|
- `GET /api/academic_periods`
|
|
- `GET /api/academic_periods/:id`
|
|
- `POST /api/academic_periods`
|
|
- `PUT /api/academic_periods/:id`
|
|
- `POST /api/academic_periods/:id/activate`
|
|
- `POST /api/academic_periods/:id/archive`
|
|
- `POST /api/academic_periods/:id/restore`
|
|
- `GET /api/academic_periods/:id/usage`
|
|
- `DELETE /api/academic_periods/:id`
|
|
|
|
Deliverable:
|
|
|
|
- Academic periods become a fully managed backend resource
|
|
|
|
### Phase 5: Add Backend Validation And Guardrails
|
|
|
|
Files:
|
|
|
|
- `server/routes/academic_periods.py`
|
|
- `models/models.py`
|
|
|
|
Work:
|
|
|
|
- Enforce required fields, type checks, date checks, overlap checks, and one-active-period behavior
|
|
- Block archive and delete when dependency rules fail
|
|
|
|
Deliverable:
|
|
|
|
- Backend owns all business-critical safeguards
|
|
|
|
### Phase 6: Implement Recurrence Spillover Detection
|
|
|
|
Files:
|
|
|
|
- `server/routes/academic_periods.py`

|
|
- `models/models.py`
|
|
|
|
Work:
|
|
|
|

|
|
- Treat them as blockers for archive and hard delete
|
|
|
|
Deliverable:
|
|
|
|
- Old periods cannot be retired while they still affect the active schedule
|
|
|
|
### Phase 7: Normalize API Serialization
|
|
|
|
Files:
|
|
|
|
- `server/routes/academic_periods.py`
|
|
- `server/serializers.py`

|
|
|
- Return academic period responses in camelCase consistently with the rest of the API
|
|
|
|
Deliverable:

|
|
|
- Add frontend client methods for create, update, activate, archive, restore, usage lookup, and hard delete
|
|
|
|
Deliverable:
|
|
|
|
- The settings page can manage academic periods through one dedicated API module
|
|
|
|
### Phase 9: Reorder The Akademischer Kalender Sub-Tabs
|
|
|
|
Files:
|
|
|
|

- Move `Import & Liste` to the second sub-tab
|
|
- Preserve controlled tab state behavior
|
|
|
|
Deliverable:
|
|

|
|
|
|
### Phase 10: Replace The Current Period Selector With A Management UI
|
|

|
- Show period metadata, active state, archived state, and available actions
|
|
|
|
Deliverable:
|
|
|
|
- The periods tab becomes a real administration UI
|
|
|
|
### Phase 11: Add Create And Edit Flows

|
|
|
|
### Phase 12: Add Archive, Restore, And Hard Delete UX

|
### Phase 14: Add Backend Tests

|
|
|
|
Deliverable:
|
|
|
|
