# Complaint Form Fix Summary

## Issue
The complaint form at `/complaints/new/` was failing with a TypeError due to incorrect usage of `QuerySet.none()`.

## Root Causes
1. **TypeError**: `QuerySet.none()` was being called as a class method instead of an instance method
2. **FieldError**: The form was trying to order by `name` field, but Location/MainSection/SubSection models use `name_en` for the display name
3. **Missing Fields**: The ComplaintForm was missing new fields added to the Complaint model

## Changes Made

### 1. Fixed `apps/complaints/forms.py`

#### PublicComplaintForm (Line 178)
**Before:**
```python
queryset=models.QuerySet.none(),
```

**After:**
```python
queryset=Department.objects.none(),
```

#### Initialize Cascading Dropdown Querysets
**Problem:** The `main_section` and `subsection` fields had `queryset=None` initially, causing:
```
'NoneType' object has no attribute '_prefetch_related_lookups'
```

**Solution:** Added initialization in `__init__` method for both ComplaintForm and PublicComplaintForm:
```python
def __init__(self, *args, **kwargs):
    super().__init__(*args, **kwargs)
    from apps.organizations.models import Location, MainSection, SubSection

    # Initialize cascading dropdowns with empty querysets
    self.fields['main_section'].queryset = MainSection.objects.none()
    self.fields['subsection'].queryset = SubSection.objects.none()

    # Load all locations (no filtering needed)
    self.fields['location'].queryset = Location.objects.all().order_by('name_en')
```

#### Added ComplaintType Import
```python
from apps.complaints.models import (
    Complaint,
    ComplaintCategory,
    ComplaintSource,
    ComplaintStatus,
    ComplaintType,  # Added
    Inquiry,
    ComplaintSLAConfig,
    EscalationRule,
    ComplaintThreshold,
)
```

#### Updated ComplaintForm with New Fields
Added the following fields to ComplaintForm class:
- `complaint_type` - Feedback type selection (Complaint/Appreciation)
- `relation_to_patient` - Patient or Relative
- `patient_name` - Name of patient involved
- `national_id` - Saudi National ID or Iqama number
- `incident_date` - Date when incident occurred
- `staff_name` - Staff member involved (if known)
- `expected_result` - Expected resolution from complainant

#### Fixed Field Ordering
Changed all `.order_by('name')` to `.order_by('name_en')` for Location, MainSection, and SubSection querysets to match the actual field names in the models.

### 2. Updated `templates/complaints/complaint_form.html`

#### New Sections Added:

1. **Feedback Type Selection**
   - Visual cards for Complaint vs Appreciation selection
   - Interactive JavaScript handlers for selection

2. **Patient Information Section**
   - Relation to Patient dropdown
   - Patient Name field
   - National ID/Iqama field
   - Incident Date field
   - Encounter ID field (optional)

3. **Organization & Location Section**
   - Hospital dropdown
   - Department dropdown
   - Location hierarchy (Location → Main Section → Subsection)
   - Staff dropdown (optional)
   - Staff Name field (optional)

4. **Complaint Details Section**
   - Description field
   - Expected Result field

5. **Enhanced JavaScript**
   - Complaint type card selection handlers
   - Hospital change handler (reloads form)
   - Location change handler (loads sections via AJAX)
   - Main Section change handler (loads subsections via AJAX)
   - Department change handler (loads staff via AJAX)
   - Form validation

6. **Updated Sidebar**
   - AI Classification information
   - SLA Information display
   - Action buttons

## Model Fields Reference

### Location Hierarchy Models
```python
# Location model
name_en = models.CharField(max_length=200)  # Display name
name_ar = models.CharField(max_length=200, blank=True)

# MainSection model
name_en = models.CharField(max_length=200)  # Display name
name_ar = models.CharField(max_length=200, blank=True)

# SubSection model
name_en = models.CharField(max_length=200)  # Display name
name_ar = models.CharField(max_length=200, blank=True)
```

### Complaint Model New Fields
```python
complaint_type = models.CharField(max_length=20, choices=ComplaintType.choices)
relation_to_patient = models.CharField(max_length=20)
patient_name = models.CharField(max_length=200)
national_id = models.CharField(max_length=20)
incident_date = models.DateField()
staff_name = models.CharField(max_length=200, blank=True)
expected_result = models.TextField(blank=True)

location = models.ForeignKey('organizations.Location')
main_section = models.ForeignKey('organizations.MainSection')
subsection = models.ForeignKey('organizations.SubSection')
```

## Verification

✅ Form imports successfully without errors
✅ All new fields are properly defined
✅ Field ordering uses correct field names (`name_en`)
✅ Template includes all new form sections
✅ JavaScript handlers implemented for cascading dropdowns
✅ Internationalization support maintained (i18n)

## Testing Checklist

- [ ] Form loads without errors at `/complaints/new/`
- [ ] Location dropdown loads all locations
- [ ] Selecting location loads sections via AJAX
- [ ] Selecting section loads subsections via AJAX
- [ ] Complaint type selection works visually
- [ ] Form validation works for all required fields
- [ ] Form submission creates complaint with all new fields
- [ ] Patient information fields display correctly
- [ ] Staff dropdown loads when department is selected

## Notes

1. **AJAX Endpoints**: The form relies on these AJAX endpoints:
   - `/organizations/ajax/main-sections/?location_id={id}`
   - `/organizations/ajax/subsections/?location_id={id}&main_section_id={id}`
   - `/complaints/ajax/physicians/?department_id={id}`

2. **Location Hierarchy**: The form implements a 3-level cascading dropdown system:
   - Level 1: Location (e.g., Riyadh, Jeddah)
   - Level 2: Main Section (e.g., Clinical, Administrative)
   - Level 3: Subsection (e.g., Outpatient, Inpatient)

3. **Complaint Type**: The form supports both Complaint and Appreciation types with a visual card-based selection interface.

4. **i18n Support**: All labels and placeholders use Django's translation system (`_("text")`) for multilingual support.
