Add auditing UI to Model-Driven App with global summary and record-specific views

[Copilot]

Implements comprehensive auditing views for the Model-Driven App UI, allowing users to view audit history both globally and for individual records.

Changes

Backend API (AuditController.cs)

Added a new REST API controller that exposes audit functionality through the following endpoints:

• GET /api/audit - List all audit records with pagination and filtering
• GET /api/audit/entity/{entityName}/{id} - Get audit history for a specific record
• GET /api/audit/details/{auditId} - Get detailed attribute changes (old/new values)
• GET /api/audit/status - Check if auditing is enabled
• POST /api/audit/status - Enable/disable auditing

Frontend Components

AuditSummaryView Component

• Displays global audit history with all tracked operations
• Shows action badges with color coding (Create=green, Update=blue, Delete=red)
• Includes toggle to enable/disable auditing at organization level
• Supports pagination and real-time refresh

AuditRecordView Component

• Shows audit history for a single record
• Expandable accordion items reveal attribute-level changes
• Displays old vs new values side-by-side
• Automatically loads when record form is opened

EntityForm Integration

• Added "Audit History" tab to entity forms for existing records
• Tab only appears for records that have been saved (not new records)
• Seamlessly integrated with existing form navigation

Navigation Enhancement

• Added "Audit History" button to main navigation sidebar
• Provides quick access to global audit summary view

Bug Fix: Audit Logic with CDM Metadata

Fixed a critical bug in XrmFakedContext.Audit.cs where null IsAuditEnabled values were incorrectly treated as disabling auditing:

Before:

if (entityMetadata.IsAuditEnabled?.Value != true)
{
    return false;  // Blocked auditing when IsAuditEnabled was null
}

After:

if (entityMetadata.IsAuditEnabled?.Value == false)
{
    return false;  // Only blocks when explicitly set to false
}
// null now allows auditing (matches Dataverse behavior)

This change ensures that CDM metadata with null audit settings works correctly, treating null as "allow auditing" rather than "deny auditing."

Testing

C# Unit Tests (AuditControllerTests.cs)

• 9 comprehensive tests covering all API endpoints
• Tests for pagination, filtering, and status management
• All tests passing

React Component Tests

• AuditSummaryView.test.tsx - 5 test cases
• AuditRecordView.test.tsx - 5 test cases
• Tests for loading states, error handling, and data display
• All tests passing

Usage Example

# Enable auditing
curl -X POST http://localhost:5000/api/audit/status \
  -H "Content-Type: application/json" \
  -d '{"isAuditEnabled": true}'

# Create a record (will be audited)
curl -X POST http://localhost:5000/api/data/v9.2/accounts \
  -H "Content-Type: application/json" \
  -d '{"name": "Test Account", "revenue": 100000}'

# View all audit records
curl http://localhost:5000/api/audit

# View audit history for specific record
curl http://localhost:5000/api/audit/entity/account/{record-id}

Screenshot

The screenshot shows the main Model-Driven App interface with the audit navigation components integrated into the sidebar.

Notes

The audit system tracks all Create, Update, and Delete operations with:

• Timestamps and user information
• Attribute-level change tracking with old/new values
• Color-coded action badges for easy identification
• Full support for pagination and filtering

This implementation leverages the existing IAuditRepository infrastructure in Fake4DataverseCore, making it easy to view and manage audit data through the web UI.
