# Lead Detail View - Complete Implementation

## Problem
When clicking "View" on a lead in the CRM dashboard, it was navigating to Django's default admin panel at `/admin/crm/lead/?lead_id=...` instead of staying within the CRM dashboard.

## Solution
Created a comprehensive lead detail page within the CRM dashboard system that displays all lead information without leaving the custom admin interface.

## What Was Implemented

### 1. Lead Detail Page Template
File: `crm/templates/crm/admin/lead_detail.html`

Features:
- **Lead Information Section**
  - Full name, email, phone
  - Source (Contact Form / Assessment Form)
  - Status with color-coded badges
  - Created and updated timestamps
  - Assigned staff member

- **Source Details Section**
  - For Contact Form leads: Shows subject, message, submission time
  - For Assessment Form leads: Shows field of expertise, years of experience, location, scores, eligibility status

- **Notes Section**
  - Textarea for adding/editing internal notes about the lead
  - Save button to update notes
  - Useful for tracking communication and follow-ups

- **Quick Actions Panel**
  - Status update dropdown with instant save
  - Convert to Project button (for non-converted leads)
  - View source links (Contact or Assessment in Django admin if needed)

- **Activity Timeline**
  - Shows chronological history of lead activities
  - Lead creation event
  - Assignment events
  - Status change events
  - Conversion events

### 2. View Functions
File: `crm/views.py`

Added 4 new view functions:

#### `admin_lead_detail(request, lead_id)`
- Displays the lead detail page
- Requires superuser authentication
- Fetches lead with all related data (contact/assessment)

#### `admin_lead_update_status(request, lead_id)`
- Updates lead status via POST request
- Logs activity in ActivityLog
- Redirects back to lead detail page

#### `admin_lead_update_notes(request, lead_id)`
- Updates lead notes via POST request
- Logs activity in ActivityLog
- Redirects back to lead detail page

#### `admin_lead_convert(request, lead_id)`
- Placeholder for lead conversion functionality
- Will be implemented with full project creation form
- Currently redirects back to lead detail

### 3. URL Routes
File: `crm/urls.py`

Added 4 new URL patterns:
```python
path('crm-admin/leads/<uuid:lead_id>/', views.admin_lead_detail, name='admin_lead_detail'),
path('crm-admin/leads/<uuid:lead_id>/update-status/', views.admin_lead_update_status, name='admin_lead_update_status'),
path('crm-admin/leads/<uuid:lead_id>/update-notes/', views.admin_lead_update_notes, name='admin_lead_update_notes'),
path('crm-admin/leads/<uuid:lead_id>/convert/', views.admin_lead_convert, name='admin_lead_convert'),
```

### 4. Updated Leads List Template
File: `crm/templates/crm/admin/leads.html`

Changed the View button JavaScript:
```javascript
// OLD (navigated to Django admin)
function viewLead(leadId) {
    window.location.href = `/admin/crm/lead/?lead_id=${leadId}`;
}

// NEW (stays in CRM dashboard)
function viewLead(leadId) {
    window.location.href = `/crm-admin/leads/${leadId}/`;
}
```

## How It Works
