Session Resume: Login Unification & Analytics Dashboard Implementation

Date: 2025-11-28 Duration: ~1.5 hours Status: ✅ COMPLETE

🎯 Objective

  1. Unify Login System: Merge separate admin and user login into a single endpoint
  2. Implement Analytics Dashboard: Create comprehensive session analytics for admins and users
  3. Improve Navigation: Add clear navigation links to new features

✅ What Was Accomplished

Phase 1: Login System Unification

Removed Duplicate Login Infrastructure

  1. ✅ Deleted /admin/login endpoint (oidc_server.py:73-96)
  2. ✅ Removed authenticate_admin() method from AuthService (auth_service.py:169-216)
  3. ✅ Unified session handling - only session['user_id'] (previously: admin_user_id + user_id)
  4. ✅ Updated /admin/logout to use unified session clearing

Updated Authentication Flow

Before:

# Two separate login endpoints
/login → session['user_id'] = user.id
/admin/login → session['admin_user_id'] = user.id

# Admin decorator checked both
admin_id = session.get('admin_user_id') or session.get('user_id')

After:

# Single login endpoint
/login → session['user_id'] = user.id
         ↓
    is_admin? → /admin/users
         ↓
    regular?  → /dashboard

# Admin decorator checks one session
user_id = session.get('user_id')

Enhanced Login Redirect Logic (oidc_server.py:509-519)

  • Supports ?redirect=admin parameter for direct admin access
  • Auto-redirects admins to /admin/users
  • Auto-redirects regular users to /dashboard
  • Handles access denied scenarios with error messages

Phase 2: Analytics Dashboard Implementation

Service Layer Enhancement

AnalyticsService (app/services/analytics_service.py:114-141)

  • ✅ Added get_user_analytics(user_id) method
    • Filters all sessions for specific user
    • Returns summary with session count and client count
    • Provides detailed session list

Existing Methods:

  • get_active_sessions() - All sessions (for admins)
  • get_client_usage_stats(client_id) - Per-client stats
  • get_user_active_clients(user_id) - User's active clients

Repository Layer (Already existed)

TokenRepository (app/repositories/token_repository.py:99-171)

  • get_active_tokens_by_client() - Detailed token list with JOINs
  • get_active_sessions_summary() - Aggregated stats by client

SQL Queries:

-- Active tokens with user and client info
SELECT token.client_id, client.name, token.user_id,
       user.username, user.email, token.created_at, token.expires_at
FROM access_tokens token
JOIN users user ON token.user_id = user.id
LEFT JOIN clients client ON token.client_id = client.client_id
WHERE token.revoked = false AND token.expires_at > NOW()
ORDER BY client.name, user.username

-- Summary by client
SELECT token.client_id, client.name,
       COUNT(DISTINCT token.user_id) as active_users,
       COUNT(token.id) as total_tokens
FROM access_tokens token
LEFT JOIN clients client ON token.client_id = client.client_id
WHERE token.revoked = false AND token.expires_at > NOW()
GROUP BY token.client_id, client.name
ORDER BY active_users DESC

API Endpoints

Admin Analytics (oidc_server.py:266-281)

@app.route('/admin/analytics')
@admin_required
def admin_analytics():
    """Shows ALL active sessions across the system"""
    analytics_service = AnalyticsService()
    analytics_data = analytics_service.get_active_sessions()

    return render_template(
        'admin/analytics.html',
        summary=analytics_data['summary'],        # Total users, tokens, clients
        by_client=analytics_data['by_client'],    # Grouped by application
        detailed_sessions=analytics_data['detailed_sessions']  # Full list
    )

User Analytics (oidc_server.py:538-560) ⭐ NEW

@app.route('/my-sessions')
def my_sessions():
    """Shows user's OWN active sessions only"""
    user_id = session.get('user_id')
    if not user_id:
        return redirect('/login')

    analytics_service = AnalyticsService()
    analytics_data = analytics_service.get_user_analytics(user_id)

    return render_template(
        'user_analytics.html',
        user=user,
        summary=analytics_data['summary'],           # User's session count
        active_sessions=analytics_data['active_sessions']  # User's sessions
    )

Frontend Templates

Admin Analytics Template (admin_templates.py:1-207) - Already existed Features:

  • 3 summary cards: Active Users, Active Tokens, Clients in Use
  • Usage by Client section with user counts
  • Detailed session list grouped by client
  • Shows: username, email, created time, expiry time
  • Auto-refresh every 30 seconds

User Analytics Template (templates/user_analytics.html) ⭐ NEW Features:

  • 2 summary cards: Active Sessions, Applications
  • Session list grouped by client application
  • Shows: session status, created time, expiry time
  • Navigation: Back to Dashboard, Logout
  • Auto-refresh every 30 seconds
  • Dark mode support

Phase 3: Navigation Enhancement

User Dashboard (templates/dashboard.html:59-69)

Added navigation button:

<a href="/my-sessions">
    <button>📊 My Sessions</button>
</a>

Admin Dashboard (templates/admin/dashboard.html:50-63)

Added navigation buttons:

<a href="/admin/analytics">
    <button>📊 Analytics</button>
</a>
<a href="/admin/clients">
    <button>Manage Clients</button>
</a>
