# Series Ticketing Implementation

## Overview
Comprehensive ticketing system for event series that allows users to purchase a single pass for all events in a series, or optionally register for individual events (drop-in model).

## Two Ticketing Models Supported

### 1. Series-Level Ticketing (Default)
**Intent:** Registrants attend all sessions in the series

**Use cases:**
- Workshop series (e.g., 4-week game dev workshop)
- Courses
- Multi-day events
- Any series where commitment to all sessions is expected

**How it works:**
- Purchase ONE series pass that grants access to ALL events
- Single payment covers the entire series
- Automatic registration for all events upon purchase
- User receives single confirmation email with full schedule

### 2. Event-Level Ticketing (Drop-in)
**Intent:** Each event can be attended independently

**Use cases:**
- Recurring meetups (e.g., monthly community calls)
- Tournaments where sessions are standalone
- Drop-in events where flexibility is key

**How it works:**
- Each event has its own ticket configuration
- Users register per event, not for the series
- Can attend just one, some, or all events
- Standard event ticketing applies

## What Was Built

### 1. Data Models

#### New Series Model (`server/models/series.js`)
Dedicated model for managing event series with:
- Series metadata (title, description, type, dates)
- Full ticket configuration (member/public pricing, capacity)
- Circle-specific pricing overrides
- Early bird pricing support
- Waitlist functionality
- Series registrations tracking
- Event registration references

#### Enhanced Event Model
Added fields to `server/models/event.js`:
- `tickets.requiresSeriesTicket` - Flag to indicate series pass is required
- `tickets.seriesTicketReference` - Reference to Series model
- `registrations.ticketType` - Added "series_pass" option
- `registrations.isSeriesTicketHolder` - Boolean flag
- `registrations.seriesTicketId` - Reference to series registration

### 2. Backend Logic

#### Series Ticket Utilities (`server/utils/tickets.js`)
Added 8 new functions:
- `calculateSeriesTicketPrice()` - Pricing with member/circle overrides
- `checkSeriesTicketAvailability()` - Real-time availability checking
- `validateSeriesTicketPurchase()` - Pre-purchase validation
- `reserveSeriesTicket()` - Temporary reservation during checkout
- `releaseSeriesTicket()` - Release abandoned reservations
- `completeSeriesTicketPurchase()` - Finalize purchase and update counts
- `checkUserSeriesPass()` - Verify if user has valid pass
- `registerForAllSeriesEvents()` - Bulk registration across all events

### 3. API Endpoints

#### Series Ticket Endpoints
- `GET /api/series/[id]/tickets/available` - Check pass availability and pricing
- `POST /api/series/[id]/tickets/purchase` - Complete series pass purchase
- `POST /api/series/[id]/tickets/check-eligibility` - Verify member status
- `GET /api/events/[id]/check-series-access` - Verify series pass ownership for event

### 4. Frontend Components

#### EventSeriesTicketCard.vue
Beautiful purple-themed card displaying:
- Series pass name and pricing
- What's included (all events listed)
- Member savings comparison
- Event schedule preview (first 3 events)
- Availability status
- Member benefit callouts

#### SeriesPassPurchase.vue
Complete purchase flow component:
- Loads series pass information
- Registration form (name/email)
- Helcim payment integration for paid passes
- Success/error handling with toast notifications
- Automatic registration for all events
- Email confirmation

#### Updated EventTicketPurchase.vue
Enhanced to detect series pass requirements:
- Checks if event requires series pass
- Shows "Series Pass Required" message with link to series
- Displays "Registered via Series Pass" for pass holders
- Graceful fallback to regular ticketing

### 5. Email Templates

#### Series Pass Confirmation Email
Professional HTML email featuring:
- Purple gradient header
- Full series pass details
- Complete event schedule with dates/times
- Member benefit callout (if applicable)
- Transaction ID (if paid)
- "What's Next" guidance
- Dashboard link

### 6. UI Integration

#### Updated Series Detail Page (`/series/[id].vue`)
- New "Get Your Series Pass" section
- Displays SeriesPassPurchase component
- Shows only if `series.tickets.enabled` is true
- Refreshes data after successful purchase
- User session integration

## Configuration Examples

const series = {
  id: "coop-game-dev-2025",
  title: "Cooperative Game Development Workshop Series",
  type: "workshop_series",
  tickets: {
    enabled: true,
    requiresSeriesTicket: true, // Must buy series pass
    allowIndividualEventTickets: false,
    currency: "CAD",
    member: {
      available: true,
      isFree: true,
      name: "Member Series Pass",

    },
    public: {
      available: true,
      price: 100.00,
      earlyBirdPrice: 80.00,
      earlyBirdDeadline: "2025-11-01T00:00:00Z",
      name: "Public Series Pass",
      description: "Access to all 4 workshops"
    },
    capacity: {
      total: 30 // Total capacity across all ticket types
    }
  }
}
```

### Example 2: Circle-Specific Pricing

```javascript
const series = {
  tickets: {
    enabled: true,
    member: {
      isFree: false,
      price: 50.00, // Default member price
      circleOverrides: {
        community: {
          isFree: true // Free for community circle
        },
        founder: {
          price: 25.00 // Discounted for founders
        },
        practitioner: {
          price: 10.00 // Heavily discounted
        }
      }
    }
  }
}
```

### Example 3: Drop-in Series (Individual Event Tickets)

```javascript
const series = {
  id: "monthly-meetup-2025",
  title: "Monthly Community Meetup",
  type: "recurring_meetup",
  tickets: {
    enabled: false, // No series-level tickets
    requiresSeriesTicket: false,
    allowIndividualEventTickets: true
  }
}

// Each event in series has its own tickets config
const event = {
  series: {
    id: "monthly-meetup-2025",
    isSeriesEvent: true
  },
  tickets: {
    enabled: true,
    member: {
      isFree: true
    },
    public: {
      available: true,
      price: 10.00
    }
