# Complaint Detail Template Internationalization Update

## Summary
Updated the complaint detail template (`templates/complaints/complaint_detail.html`) to display all information captured by the public complaint form with proper internationalization support.

## Changes Made

### 1. Contact Information Section
Added a new section that displays contact information for public complaints:
- **Full Name**: Displays `contact_name` field
- **Email Address**: Displays `contact_email` field  
- **Phone Number**: Displays `contact_phone` field
- **Visibility**: Only shown for public complaints (when `creator_type == 'public'`)

### 2. Location Information Section
Enhanced the existing location section to display hierarchical location data:
- **Region**: Displays `region` field
- **City**: Displays `city` field
- **Branch**: Displays `branch` field
- **Visibility**: Only shown for public complaints (when `creator_type == 'public'`)

### 3. Additional Information Section
Added a new section for additional details captured from public forms:
- **Date of Incident**: Displays `incident_date` field
- **Expected Result**: Displays `expected_result` field
- **Visibility**: Only shown when these fields have values

## Internationalization Implementation

All new sections use Django's internationalization framework:
- All labels use `{% trans %}` template tags for translation
- Labels are consistent with the public form implementation
- Translations are defined in `locale/en/LC_MESSAGES/django.po` and `locale/ar/LC_MESSAGES/django.po`

### Translation Keys Added
```django
{% trans "Contact Information" %}
{% trans "Full Name" %}
{% trans "Email Address" %}
{% trans "Phone Number" %}
{% trans "Location Information" %}
{% trans "Region" %}
{% trans "City" %}
{% trans "Branch" %}
{% trans "Additional Information" %}
{% trans "Date of Incident" %}
{% trans "Expected Result" %}
```

## Template Structure

The updated template now includes:

```django
{# Contact Information Section (Public only) #}
{% if complaint.creator_type == 'public' %}
  <h4 class="font-semibold text-lg mb-3">{% trans "Contact Information" %}</h4>
  <!-- Contact details grid -->
{% endif %}

{# Location Information Section (Public only) #}
{% if complaint.creator_type == 'public' %}
  <h4 class="font-semibold text-lg mb-3">{% trans "Location Information" %}</h4>
  <!-- Location details grid -->
{% endif %}

{# Additional Information Section (Conditional) #}
{% if complaint.incident_date or complaint.expected_result %}
  <h4 class="font-semibold text-lg mb-3">{% trans "Additional Information" %}</h4>
  <!-- Additional details -->
{% endif %}
```

## Verification

### Template Validation
✅ Template loads successfully with Django's template loader
✅ No syntax errors detected
✅ All template tags are properly closed
✅ Custom `math` template tag library is available

### Internationalization Status
✅ All new text uses `{% trans %}` tags
✅ Translation keys are consistent with public form
✅ Bilingual support (English/Arabic) maintained

## Benefits

1. **Complete Information Display**: All data captured from public forms is now visible in the detail view
2. **Consistent User Experience**: Public complaint submitters can see all information they provided
3. **Better Tracking**: Staff can view contact information for follow-up
4. **Location Context**: Hierarchical location data provides better context for investigations
5. **Internationalization Ready**: All new content is properly internationalized

## Testing Checklist

- [ ] Verify template loads without errors
- [ ] Test with public complaint (creator_type='public')
- [ ] Test with internal complaint (creator_type='internal')
- [ ] Verify Contact Information section displays for public complaints
- [ ] Verify Location Information section displays for public complaints
- [ ] Verify Additional Information section displays when data exists
- [ ] Test English language rendering
- [ ] Test Arabic language rendering

## Files Modified

1. `templates/complaints/complaint_detail.html` - Added three new sections with i18n support

## Related Files

- `templates/complaints/public_complaint_form.html` - Source form that captures this data
- `apps/complaints/models.py` - Complaint model with field definitions
- `locale/en/LC_MESSAGES/django.po` - English translations
- `locale/ar/LC_MESSAGES/django.po` - Arabic translations

## Deployment Notes

No database migrations required - all fields already exist in the Complaint model.
No configuration changes required - uses existing i18n infrastructure.

Template changes are backward compatible and will not affect existing internal complaints.
