# Promoter System Implementation

This document outlines the comprehensive promoter system implemented for AperoNight, providing professional event organizers with powerful tools to manage their events and track their performance.

## Overview

The promoter system allows professional users (marked with `is_professionnal: true`) to create, manage, and analyze their events through a dedicated interface. This system includes:

- **Role-based access control** - Only professional users can manage events
- **Comprehensive dashboard** - Real-time metrics and revenue tracking
- **Event management workflow** - Easy CRUD operations for events
- **Revenue analytics** - Monthly revenue trends and detailed metrics

## Key Features Implemented

### 1. User Role Management

**File**: `app/models/user.rb`

The system uses the existing `is_professionnal` boolean field to determine promoter privileges:

```ruby
def can_manage_events?
  # Only professional users can manage events
  is_professionnal?
end

def promoter?
  # Alias for can_manage_events? to make views more semantic
  can_manage_events?
end
```

### 2. Conditional Navigation

**File**: `app/views/components/_header.html.erb`

Navigation items are conditionally displayed based on user status:

- **Desktop Navigation**: "Créer un événement" and "Mes événements" links
- **Mobile Navigation**: Same functionality with appropriate icons
- **Responsive Design**: Maintains clean UI across all device sizes

### 3. Promoter Dashboard

**File**: `app/controllers/pages_controller.rb` & `app/views/pages/dashboard.html.erb`

The dashboard provides comprehensive business intelligence for promoters:

#### Key Metrics Cards
- **Total Revenue**: Sum of all completed event orders
- **Tickets Sold**: Count of active tickets across all events
- **Published Events**: Count of live/published events
- **Draft Events**: Count of events in preparation

#### Monthly Revenue Chart
- **6-Month Trend**: Visual representation of revenue over time
- **Progressive Bars**: Easy-to-read revenue comparison
- **Responsive Design**: Works on all screen sizes

#### Recent Events Widget
- **Quick Overview**: Last 5 events with status indicators
- **Status Badges**: Visual indicators for draft/published/cancelled states
- **Ticket Sales**: Shows tickets sold per event
- **Quick Actions**: Direct links to event management

#### Recent Orders Table
- **Transaction History**: Latest 10 orders for promoter events
- **Customer Information**: Buyer details and contact info
- **Revenue Tracking**: Order amounts and dates
- **Event Association**: Clear event-to-order relationship

### 4. Event Management Workflow

The existing event management system provides:

#### Event Creation
- **Intuitive Form**: Step-by-step event creation process
- **Auto-Generated Slugs**: SEO-friendly URLs from event names
- **Rich Metadata**: Full event details including location and timing
- **Draft System**: Create and refine before publishing

#### Event List Management
- **Tabular View**: Clean, scannable list of all events
- **Status Indicators**: Visual badges for event states
- **Quick Actions**: Inline buttons for common operations
- **Bulk Operations**: Efficient management of multiple events

#### Publishing Workflow
- **Draft → Published**: One-click publishing when ready
- **State Management**: Clean state transitions
- **Rollback Capability**: Can unpublish if needed

## Technical Implementation Details

### Database Schema

The system leverages existing database structure:
- **Users Table**: `is_professionnal` boolean field
- **Events Table**: Belongs to user, has states enum
- **Orders Table**: Links to events and users
- **Tickets Table**: Links to orders and events

### Revenue Calculations

Revenue metrics are calculated with optimized queries:

```ruby
# Total revenue across all promoter events
@total_revenue = current_user.events
                            .joins(:orders)
                            .where(orders: { status: ['paid', 'completed'] })
                            .sum('orders.total_amount_cents') / 100.0

# Monthly revenue trend (6 months)
@monthly_revenue = (0..5).map do |months_ago|
  start_date = months_ago.months.ago.beginning_of_month
  end_date = months_ago.months.ago.end_of_month
  
  revenue = current_user.events
                       .joins(:orders)
                       .where(orders: { status: ['paid', 'completed'] })
                       .where(orders: { created_at: start_date..end_date })
                       .sum('orders.total_amount_cents') / 100.0
  
  { month: start_date.strftime("%B %Y"), revenue: revenue }
end.reverse
```

### Security & Authorization

- **Controller Guards**: `before_action :ensure_can_manage_events!`
- **Model-level Checks**: User role validation in models
- **View-level Conditionals**: UI elements only shown to authorized users
- **Route Protection**: Promoter namespace requires authentication

### Performance Optimizations

- **Eager Loading**: `includes(:orders, :tickets)` to prevent N+1 queries
- **Efficient Queries**: Database-level aggregations for metrics
- **Caching Ready**: Structure allows for future caching implementation
- **Paginated Results**: Large datasets handled efficiently

## User Experience Enhancements

### Dashboard Design Philosophy
- **Information Hierarchy**: Most important metrics prominently displayed
- **Progressive Disclosure**: Detailed information available on demand
- **Action-Oriented**: Quick access to common tasks
- **Responsive First**: Mobile-friendly from the ground up

### Visual Design Elements
- **Color Coding**: Consistent color schemes for different data types
- **Iconography**: Lucide icons for clear visual communication
- **Status Indicators**: Immediate visual feedback on event states
- **Gradient Cards**: Attractive metric display with brand consistency

### Navigation Improvements
- **Contextual Links**: Navigation adapts based on user type
- **Breadcrumbs**: Clear navigation path for complex workflows
- **Quick Actions**: Common tasks accessible from multiple locations
