Database Schema

ContactSubmission Model

class ContactSubmission(models.Model):
    """Contact form submission from users."""
    
    # Primary Fields
    id = models.UUIDField(primary_key=True, default=uuid.uuid4)
    ticket_number = models.CharField(max_length=50, unique=True)
    
    # Contact Information
    name = models.CharField(max_length=255)
    email = models.EmailField()
    
    # Submission Details
    subject = models.CharField(max_length=255)
    message = models.TextField()
    category = models.CharField(max_length=50, choices=CATEGORY_CHOICES)
    
    # Status Management
    status = models.CharField(max_length=20, choices=STATUS_CHOICES, default='pending')
    
    # User Relationships
    user = models.ForeignKey(User, null=True, blank=True, on_delete=models.SET_NULL)
    assigned_to = models.ForeignKey(User, null=True, blank=True, on_delete=models.SET_NULL)
    resolved_by = models.ForeignKey(User, null=True, blank=True, on_delete=models.SET_NULL)
    
    # Timestamps
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)
    resolved_at = models.DateTimeField(null=True, blank=True)
    
    # Admin Notes
    admin_notes = models.TextField(blank=True)

Indexes

• status, -created_at - For filtering by status with recent first
• category, -created_at - For filtering by category with recent first
• ticket_number - For quick ticket lookup

python manage.py migrate contact

Testing Checklist

Functional Tests

• Submit contact form without authentication
• Submit contact form with authentication
• Verify ticket number generation
• Verify confirmation email sent
• Verify admin notification sent
• List submissions as moderator
• Filter submissions by status
• Filter submissions by category

Next Steps

Frontend Integration

1. Create Contact form component
2. Create service layer for API calls
3. Add to navigation/footer
