# MODULE: Aether Events — Badges

**Module Path:** `src/routes/events/[event_id]/(badges)/badges/`
**API Module:** `src/lib/ae_events/ae_events__event_badge.ts`
**Database:** `db_events.badge` (Dexie IndexedDB table)
**Last Updated:** 2026-02-26 (rev 3)

---

## Overview

The Badges module manages event attendee badges with support for:
- **External system imports** (iMIS, Zoom, Novi, Impexium, Confex, Cvent, and others)
- **Field override protection** to prevent staff/attendee edits from being overwritten by automated syncs
- **Multi-tier access control** for field editing
- **QR code generation** for badge scanning
- **Print tracking** (count, first/last print datetime)
- **Advanced search and filtering**

---

## Critical Design Pattern: Override Fields

### Purpose
The `*_override` fields pattern protects data from being overwritten during scheduled cron syncs from external systems. This is essential because:
1. Staff may need to correct imported data
2. Attendees may be allowed to self-update certain fields (e.g., preferred name, pronouns)
3. External systems often have outdated or incorrect data
4. Changes should persist across multiple sync cycles

### How It Works

**Import Behavior:**
```
External System → Aether API → Populates REGULAR fields only
                                (never touches *_override fields)
```

**Display Behavior:**
```
UI Display Logic:
1. IF `*_override` field has value → USE IT (highest priority)
2. ELSE IF regular field has value → USE IT (fallback)
3. ELSE → Display placeholder/empty
```

**Example — Full Name:**
```typescript
// API imports from iMIS
badge.given_name = "Robert"
badge.family_name = "Smith"
badge.full_name = "Robert Smith"  // Auto-computed

// Staff edits to preferred name
badge.full_name_override = "Bob Smith"

// Display in UI
display_name = badge.full_name_override || badge.full_name || "-- no name --"
// Result: "Bob Smith"

// Next cron sync from iMIS
// ✅ badge.full_name updated to "Robert J. Smith" (middle initial added)
// ✅ badge.full_name_override remains "Bob Smith" (PROTECTED)
// ✅ Display still shows "Bob Smith"
```

### Override Fields (7 total)

| Regular Field | Override Field | Purpose | Editable By |
|---|---|---|---|
| `professional_title` | `professional_title_override` | Job title display | Staff, Attendee |
| `full_name` | `full_name_override` | Preferred name, pronouns | Staff, Attendee |
| `affiliations` | `affiliations_override` | Organization display | Staff, Attendee |
| `email` | `email_override` | Contact email override | Staff only |
| `location` | `location_override` | City/State/Country display | Staff, Attendee |
| `badge_type` | `badge_type_override` | Badge category label (varies per Event/Template) | Staff only |
| `badge_type_code` | `badge_type_code_override` | Badge access level code (varies per Event/Template) | Staff only |

### Sync Safety Rules

**Automated Sync (Cron Jobs):**
- ✅ CAN update: All regular fields (`given_name`, `family_name`, `email`, `affiliations`, etc.)
- ❌ CANNOT update: Any `*_override` field
- ❌ CANNOT delete: Any `*_override` value

**Manual Staff Edit:**
- ✅ CAN update: Any field (including overrides)
- ✅ CAN clear: Override fields (reverts to regular field)

**Attendee Self-Service Edit:**
- ✅ CAN update: Only specific override fields (per event config)
- ✅ CAN clear: Their own override fields
- ❌ CANNOT edit: Regular fields, badge_type, email_override

---

## External System Integration

### Supported Import Sources
- **iMIS** (Association Management)
- **Zoom** (Virtual event registration)
- **Novi AMS** (Association Management)
- **Impexium** (Association Management)
- **Confex** (Event abstract management)
- **Cvent** (Event registration)
- **Custom CSV/Excel** imports

### Data Flow Direction
```
External Systems ─────────> Aether
    (READ ONLY)          (WRITE + DISPLAY)
```

**Important:** Aether is **pull-only** — does not push changes back to external systems. This prevents sync conflicts and maintains external systems as the source of truth for base data.

### Sync Behavior
- **Frequency:** Scheduled cron jobs (typically hourly, daily, or on-demand)
- **Method:** Full sync or incremental (depends on external system API)
- **Conflict Resolution:** Override fields always win

**Pseudocode:**
```python
def sync_badge_from_external(external_badge_data, existing_badge):
    # Update regular fields from external source
    existing_badge.given_name = external_badge_data.first_name
    existing_badge.family_name = external_badge_data.last_name
    existing_badge.email = external_badge_data.email
    existing_badge.affiliations = external_badge_data.organization
    existing_badge.badge_type_code = external_badge_data.registration_type

    # NEVER TOUCH OVERRIDE FIELDS
    # existing_badge.full_name_override ← PROTECTED
    # existing_badge.affiliations_override ← PROTECTED
    # existing_badge.email_override ← PROTECTED

    return existing_badge
```

---

## Access Control & Edit Permissions

### Access Levels (Ascending)
1. **Anonymous** — No access to badges
2. **Public** — View public event info only (no badge access)
3. **Authenticated** — View own badge, limited self-edit
4. **Trusted** — Search all badges, view all, edit own
5. **Administrator** — Full CRUD, bulk operations, override any field
6. **Manager** — All administrator + event configuration
7. **Super** — All manager + cross-event operations

### Current Implementation (v3)

**Quick Edit Feature** ([badge_id]/+page.svelte → ae_comp__badge_obj_view.svelte)

**Edit Mode Trigger:**
- URL hash `#review` enables edit mode
- Sets `$ae_loc.edit_mode = true`
- Shows Save/Cancel buttons

**Currently Editable Fields:**
```typescript
// Lines 90-96 in ae_comp__badge_obj_view.svelte
editable_full_name_override: string | null
editable_professional_title_override: string | null
editable_affiliations_override: string | null  // textarea
editable_location_override: string | null
editable_allow_tracking: boolean | null
editable_email: string | null
editable_badge_type_code: string | null
```

**UI Components:**
- Input fields shown when `edit_mode_active === true`
- Save button calls `handle_save_changes()` (Line 365)
- Cancel button calls `handle_cancel_changes()` (Line 450)
- Only changed fields sent to API (`update_ae_obj__event_badge`)

### Future Planned Enhancement

**Event-Level Configuration:** `event.mod_badges_json.edit_permissions`

```json
{
  "authenticated": {
    "can_edit": ["full_name_override", "professional_title_override", "affiliations_override", "location_override"],
    "requires_approval": false
  },
  "trusted": {
    "can_edit": ["full_name_override", "professional_title_override", "affiliations_override", "location_override", "email_override"],
    "can_view_all": true,
    "requires_approval": false
  },
  "administrator": {
    "can_edit": "*",
    "can_bulk_edit": true,
    "can_delete": true
  }
}
```

**Status:** Placeholder UI exists, JSON config not yet implemented.

## Search & Filter Capabilities

### Search Component
**File:** `ae_comp__badge_search.svelte`

### Multi-Word Search Fix (2026-02-26)
Fulltext search now correctly handles multi-word queries by splitting on whitespace and applying AND logic per word:
```typescript
// "scott idem" → LIKE '%scott%' AND LIKE '%idem%'
// Previously: LIKE '%scott idem%' (failed to match)
const words = qry.split(/\s+/).filter(w => w.length > 0);
for (const word of words) {
    search_query.and.push({ field: 'default_qry_str', op: 'like', value: `%${word}%` });
}
```
**Committed:** dc0f3066

### Available Filters

**Fulltext Search** (All Users)
- Searches: `default_qry_str` database field
- Includes: Name, email, external IDs
- Type: `LIKE %query%` (case-insensitive)
- Trigger: Enter key or 3+ characters typed

**Advanced Filters** (Trusted Access & Above)
```typescript
// Badge Type Filter
badge_type_code: 'current_member' | 'inactive_member' | 'ex_all' | 'staff' | etc.
// Note: Badge types are defined per Event and Event Badge Template in database table records.
// Common types include: member, nonmember, guest, exhibitor, staff
// This is a work in progress - types vary by event configuration.

// Print Status Filter
qry_printed_status: 'all' | 'printed' | 'not_printed'

// Affiliations Search
qry_affiliations: string  // Separate filter for organization search

// Sort Options
qry_sort_order:
  - 'name_asc' / 'name_desc'
  - 'updated_desc' / 'updated_asc'
  - 'print_count_desc'
  - 'print_first_desc' / 'print_last_desc'
  - 'badge_type_asc'
  - 'affiliations_asc'
```

### QR Scan Search
- Scans badge QR code
- Extracts badge ID
- Auto-fills search with ID
- Jumps to badge detail view

### Search Implementation Pattern
**File:** `badges/+page.svelte` (Lines 117-365)

**Strategy:** Standardized Reactive Search Pattern (Aether UI V3)
1. **Isolate dependencies** into stable `$derived` object
2. **Debounced effect** (300ms) triggers search
3. **Fast Path:** Search IDB first (if not `remote_first`)
4. **Revalidate:** API request updates IDB
5. **LiveQuery:** UI auto-updates from IDB changes

**Search API:** `events_func.search__event_badge()`
```typescript
await search__event_badge({
  api_cfg: $ae_api,
  event_id: event_id,
  fulltext_search_qry_str: qry_str || null,
  type_code: type_code || null,
  printed_status: printed_status,
  affiliations_qry_str: aff_str || null,
  order_by_li: order_by_li,
  limit: 150,
  log_lvl: 0
})
```

---

## Badge Display Logic

### Name Display Priority
```typescript
// Component: ae_comp__badge_obj_li.svelte (Lines 113-121)
if (event_badge_obj?.full_name_override)
    display: full_name_override
else if (event_badge_obj?.full_name)
    display: full_name
else
    display: given_name + ' ' + family_name
```

### Badge View Page
**Route:** `/events/[event_id]/badges/[badge_id]`

**Components:**
- `+page.svelte` — Container with LiveQuery for badge data
- `ae_comp__badge_obj_view.svelte` — Full badge display + edit UI

**LiveQueries:**
```typescript
lq__event_badge_obj = liveQuery(() => db_events.badge.get(event_badge_id))
lq__event_badge_template_obj = liveQuery(() =>
  db_events.badge_template.get(badge.event_badge_template_id)
)
```

**Loading States:**
- `is_loading_idb` — Waiting for initial IDB lookup
- If badge not found → "Badge Not Found" error with reload button
- Loader spinner while fetching

---

## Badge Templates

### Purpose
Badge templates define the visual layout and content structure for printed badges:
- Header images/logos
- Field positions and font sizes
- QR code placement
- Ticket/option indicator display
- WiFi credentials display

### Template Selection
Each badge references an `event_badge_template_id`. The template controls:
- Layout (front/back)
- Branding elements
- Which fields to show
- Field formatting rules

### Template Loading
Templates are loaded alongside badges via `inc_template` parameter:
```typescript
load_ae_obj_id__event_badge({
  event_badge_id: badge_id,
  inc_template: true  // Also loads template
})
```

---

## Print Tracking

### Print Fields
```typescript
print_count: number             // Increments each print
print_first_datetime: string    // ISO datetime of first print
print_last_datetime: string     // ISO datetime of most recent print
```

### Print Button (Implemented 2026-02-26)
The `handle_print_badge()` function in `ae_comp__badge_obj_view.svelte` increments the count and records timestamps:
```typescript
async function handle_print_badge() {
    const now = new Date().toISOString();
    const current_print_count = $lq__event_badge_obj.print_count ?? 0;
    const data_to_update = {
        print_count: current_print_count + 1,
        print_last_datetime: now
    };
    if (current_print_count === 0) {
        data_to_update.print_first_datetime = now;  // Only set on first print
    }
    await events_func.update_ae_obj__event_badge({ ... });
}
```

Button has `data-testid="badge-print-btn"` and shows loading/done/error states with icon feedback.

### Print Workflow
1. **Pre-Print:** Check `print_count` to warn if already printed
2. **Print:** `window.print()` — standard browser print dialog. Works well in Chrome, Chromium, and Firefox. Chrome is the recommended browser for onsite badge printing (most stable in production).  
3. **Post-Print:** Handled by `handle_print_badge()` — count + timestamps updated
4. **Audit:** Print history available for staff review

**Browser vs Electron:** Badge printing does NOT require the Electron native app. The standard browser print dialog works well across Chrome, Chromium, and Firefox. The Electron native app is specialized for the **Events Pres Mgmt Launcher only** and should not be assumed available for badge stations.

**Current Status:** Button records print event and updates IDB. The `window.print()` call still needs to be wired to the button — see Future Enhancements.

## Database Schema

### IndexedDB Table: `badge`
**File:** `src/lib/ae_events/db_events.ts` (Lines 841-852)

**Indexed Fields:**
```typescript
badge: `
  event_badge_id_random, event_badge_id, id,
  event_id, event_id_random,
  full_name, full_name_override, email, email_override,
  affiliations, affiliations_override,
  badge_type, badge_type_code, badge_type_code_override, badge_type_override,
  external_event_id, external_id, external_person_id,
  default_qry_str,
  alert,
  tmp_sort_1, tmp_sort_2,
  print_count, print_first_datetime, print_last_datetime,
  enable, hide, priority, sort, group, notes, created_on, updated_on
`
```

### Saved Properties
**File:** `ae_events__event_badge.ts` (Lines 495-563)

**Complete field list** (67 fields total):
- Identity: `id`, `event_badge_id`, `event_id`, `event_badge_template_id`

- Professional: `professional_title`, `professional_title_override`
- Display: `full_name`, `full_name_override`
- Organization: `affiliations`, `affiliations_override`
- Contact: `email`, `email_override`
- Address: `address_line_1`, `address_line_2`, `address_line_3`, `city`, `country_subdivision_code`, `state_province`, `state_province_abb`, `postal_code`, `country_alpha_2_code`, `country`, `full_address`
- Location: `location`, `location_override`
- Classification: `badge_type`, `badge_type_code`, `badge_type_override`, `badge_type_code_override`
- External: `external_event_id`, `external_id`, `external_person_id`
- Search: `query_str`, `default_qry_str`
- System: `alert`, `enable`, `hide`, `priority`, `sort`, `group`, `notes`, `created_on`, `updated_on`
- Print: `print_count`, `print_first_datetime`, `print_last_datetime`
- Sorting: `tmp_sort_1`, `tmp_sort_2`

## API Functions

### CRUD Operations
**File:** `src/lib/ae_events/ae_events__event_badge.ts`

```typescript
// Load single badge
load_ae_obj_id__event_badge({ event_badge_id, event_id, inc_template })

// Load badge list
load_ae_obj_li__event_badge({ event_id, view, limit, order_by_li })

// Search badges (V3 API)
search__event_badge({
  event_id,
  fulltext_search_qry_str,
  type_code,
  printed_status,
  affiliations_qry_str,
  order_by_li
})

// Create badge
create_ae_obj__event_badge({ event_id, data_kv })

// Update badge
update_ae_obj__event_badge({ event_badge_id, event_id, data_kv })

// Delete badge
delete_ae_obj_id__event_badge({ event_badge_id, event_id, method })
```

### Field Processing
**Function:** `process_ae_obj__event_badge_props()`

**Processing Steps:**
1. Map `*_random` fields to clean names (`event_badge_id_random` → `event_badge_id`)
2. Set primary `id` field from `event_badge_id`
3. Ensure `event_id` is set (from function parameter if missing)
4. Calculate `tmp_sort_1` and `tmp_sort_2` for efficient sorting
5. Return processed objects

**Critical Fix (2026-02-26):** All CRUD functions now return **processed** data (matches IDB cache) instead of raw API responses. This ensures consistency between function return values and cached data.

    ├── +page.ts            # Badge loader (non-blocking)
    └── ae_comp__badge_obj_view.svelte  # Badge display + edit
```

### Key Components

**Badge List Page** (`+page.svelte`)
- **LiveQuery:** Reactive badge list from IDB
- **Search Pattern:** Debounced search with fast path + revalidation
- **ID List:** `event_badge_id_li` drives LiveQuery
- **Loading State:** Shows spinner when `search_status === 'loading'`

**Badge Search** (`ae_comp__badge_search.svelte`)
- **Form Mode:** Toggle between search form and QR scanner
- **Filters:** Badge type, print status, affiliations, sort order (trusted+ only)
- **Fulltext:** Name/email search (all users)
- **QR Scan:** Integrated QR scanner for badge ID lookup

**Badge List Display** (`ae_comp__badge_obj_li.svelte`)
- **Visibility Filter:** Respects `hide` flag (trusted+ sees all)
- **Display Logic:** Override → regular → fallback pattern
- **Print Indicator:** Green checkmark badge shows `print_count`
- **Metadata:** ID, created/updated timestamps (edit mode only)

**Badge Detail View** (`ae_comp__badge_obj_view.svelte`)
- **Edit Mode:** Activated by edit button (or `#review` URL hash for future self-service)
- **Condition:** Renders only when BOTH `$lq__event_badge_obj` AND `$lq__event_badge_template_obj` are non-null
- **Form Binding:** Direct `bind:value` on editable fields
- **Dynamic Sizing:** Font size adjusts based on text length
- **Print Preview:** Full badge layout with template
- **Save Handler:** Only sends changed fields to API
- **`data-testid` attributes:** `badge-edit-btn`, `badge-save-btn`, `badge-cancel-btn`, `badge-print-btn`, `badge-professional-title-input` — use these in tests

---

## Testing Status

### Current Test Coverage
- ✅ Badge list loads (all 6 data integrity tests passing)
- ✅ Badge template list loads and displays
- ✅ Badge template form renders and populates correctly
- ✅ Badge template values persist in edit form
- ✅ Electron bridge compatibility (graceful degradation in browser)
- ✅ Badge field processor handles missing optional fields
- ✅ Badge type filter tests
- ✅ Badge template relationship tests
- ✅ **Attendee workflow test** — navigate → edit professional title → print → return (d1ded2d4)

### Key Test Lessons Learned

**Search API path is FLAT, not nested.** `search_ae_obj_v3` builds `/v3/crud/{obj_type}/search` — always flat regardless of the parent relationship. Mocks must match this:
```typescript
// CORRECT — flat path
url.includes('/v3/crud/event_badge/search') && method === 'POST'
// WRONG — nested path, mock will never fire
url.includes(`/v3/crud/event/${event_id}/event_badge/search`) && method === 'POST'
```

**List API (GET) is also FLAT with query params.** `get_ae_obj_li_v3` builds `/v3/crud/{obj_type}/?for_obj_id=...` — always flat. Mocks must check `url.includes('/v3/crud/event_badge_template/') && url.includes('for_obj_id')`.

**CSS `input[value*=...]` selectors don't work with Svelte bind:value.** The CSS selector checks the HTML *attribute*; Svelte's `bind:value` sets the DOM *property* only. In Playwright tests, use `page.getByLabel()` or `locator.inputValue()` instead.

**Dexie requires `_random` ID fields.** Badge objects saved to IDB must include:
```typescript
event_badge_id_random: string  // Must be present or Dexie skips the object
id_random: string              // Also checked
// Error: "Object is missing a valid ID for table 'badge'"
```
All API mock responses in tests need these fields.

**Badge view requires both badge AND template.** `ae_comp__badge_obj_view.svelte` wraps everything in `{#if $lq__event_badge_obj && $lq__event_badge_template_obj}` — if the template isn't loaded, edit/print buttons and the badge itself don't render. Tests must mock the badge template endpoint.

**Badge GET endpoint (single object):** `/v3/crud/event_badge/{id}` (NOT nested under event). Matches `api.get_ae_obj_v3()` which uses the flat path.

**Badge PATCH endpoint (update):** `/v3/crud/event/${event_id}/event_badge/${badge_id}` (nested under event). Matches `api.patch_ae_obj_v3()` which uses the nested path.

**Use `data-testid` for test selectors.** Key buttons have targets: `badge-edit-btn`, `badge-save-btn`, `badge-cancel-btn`, `badge-print-btn`, `badge-professional-title-input`.

### Remaining Test Issues
None — all current badge tests passing as of 2026-02-26 (f5e98b8c).

## Known Issues & Future Enhancements

### Known Issues
1. **Test Infrastructure:** Mock API routes not connecting to page requests
2. **Session Cold-Start:** Potential race condition on first load (same as pres mgmt module)
3. **Type Definitions:** Some TypeScript errors on external package types (pre-existing)

### Future Enhancements
1. **Access-Based Edit Permissions:** Implement JSON config for field-level access control
2. **Print Functionality:** Wire up `window.print()` to the print button. Standard browser print API — works well in Chrome/Chromium/Firefox for badge label printing. Electron is NOT needed.
3. **Batch Operations:** Bulk update, bulk print, bulk export
4. **Audit Log:** Track who edited which fields and when
5. **Photo Badges:** Support badge photo upload and display
6. **Custom Badge Layouts:** Dynamic template selection per badge type
7. **Real-Time Sync:** WebSocket updates for multi-device badge printing stations
8. **Approval Workflow:** Require manager approval for certain field changes

## Development Guidelines

### Adding New Override Fields
1. Add `{field}_override` to database schema
2. Add to `properties_to_save` array in `ae_events__event_badge.ts`
3. Update display logic to check override first
4. Add to editable fields in `ae_comp__badge_obj_view.svelte`
5. Update access control config
6. Document in this file

### Testing Override Fields
```typescript
// Simulate external sync
badge.given_name = "External Value"

// User edits
badge.given_name_override = "User Value"

// Next sync (should NOT change override)
badge.given_name = "Updated External Value"

// Display should still show "User Value"
assert(display === badge.given_name_override)
```

### Debugging Search Issues
```typescript
// Enable search logging
log_lvl: 2

// Check search params object
console.log('Search params:', search_params)

// Verify API request
console.log('API request:', { event_id, fulltext_search_qry_str, type_code })

// Check returned IDs
console.log('Badge IDs:', event_badge_id_li)

// Verify IDB contents
db_events.badge.toArray().then(console.log)
```
