Public Complaint Form Examination Report

Executive Summary

The public complaint form is designed to allow users to submit complaints without authentication using a 4-level cascading dropdown taxonomy system (Domain → Category → Subcategory → Classification).

Current Implementation Status

✅ Working Components

1. Backend API (/complaints/public/api/load-categories/)

• Status: ✅ FULLY FUNCTIONAL
• Returns: All categories with 4-level hierarchy
• Response Structure:

{
  "categories": [
    {
      "id": "UUID",
      "name_en": "CLINICAL",
      "name_ar": "سريري",
      "code": "",
      "parent_id": null,
      "level": 1,
      "domain_type": "CLINICAL",
      "description_en": "",
      "description_ar": ""
    }
  ]
}

2. URL Routing

• Status: ✅ CONFIGURED CORRECTLY
• Path: path("public/api/load-categories/", ui_views.api_load_categories, name="api_load_categories")
• Namespace: complaints:api_load_categories

3. jQuery Loading

• Status: ✅ LOADED CORRECTLY
• Location: templates/layouts/public_base.html
• Source: https://code.jquery.com/jquery-3.7.1.min.js

4. API View Function

• Status: ✅ IMPLEMENTED CORRECTLY
• File: apps/complaints/ui_views.py
• Function: api_load_categories(request)
• Features:
  • Returns system-wide categories when no hospital_id provided
  • Returns hospital-specific + system-wide categories when hospital_id provided
  • Properly ordered by level, order, name_en
  • Returns all necessary fields for 4-level cascade

⚠️ Potential Issues

1. JavaScript in Template

File: templates/complaints/public_complaint_form.html

Issues Identified:

1. Initial Load Logic: The form should automatically load domains (level 1) on page load, but the JavaScript only loads categories when hospital changes
2. Error Handling: Limited error handling for API failures
3. Console Logging: Extensive console.log statements that should be removed in production

JavaScript Flow:

1. Page loads → Hospital dropdown has no change event → No domains loaded
2. User selects hospital → Loads all categories
3. Populates domain dropdown (level 1, parent_id=null)
4. User selects domain → Loads all categories again
5. Populates category dropdown (level 2, parent_id=domain_id)
6. User selects category → Loads all categories again
7. Populates subcategory dropdown (level 3, parent_id=category_id)
8. User selects subcategory → Loads all categories again
9. Populates classification dropdown (level 4, parent_id=subcategory_id)

Problem: The form starts with empty domain dropdown until a hospital is selected. This may confuse users.

2. Form Validation

• Status: ✅ IMPLEMENTED
• Required Fields: Name, Email, Phone, Hospital, Domain, Category, Subcategory, Description
• Note: Classification is optional (can be empty)

3. Complaint Creation

• Status: ✅ IMPLEMENTED
• Process:
  1. Validates all required fields
  2. Creates Complaint object with all 4 taxonomy levels
  3. Generates unique reference number
  4. Triggers AI analysis in background
  5. Returns success message

Data Flow Analysis

Category Hierarchy Structure

Level 1: Domain (parent_id=null)
  ├── Level 2: Category (parent_id=domain_id)
  │   ├── Level 3: Subcategory (parent_id=category_id)
  │   │   └── Level 4: Classification (parent_id=subcategory_id)

Sample Data from API

Level 1 (Domains):
- CLINICAL (سريري)
- MANAGEMENT (إداري)
- RELATIONSHIPS (علاقات)

Level 2 (Categories under RELATIONSHIPS):
- Communication (التواصل)
- Institutional Issues (القضايا المؤسسية)

Level 3 & 4: (Subcategories and Classifications)

Browser Testing Needed

To fully diagnose the JavaScript issue, the following browser tests should be performed:

Test 1: Initial Page Load

1. Open http://localhost:8000/complaints/public/submit/
2. Check browser console for errors
3. Verify domain dropdown is populated (or check if it's empty)

Test 2: Hospital Selection

1. Select a hospital from dropdown
2. Check network tab for API call to /complaints/public/api/load-categories/
3. Verify domain dropdown populates with 3 domains

Test 3: Dropdown Cascade

1. Select "RELATIONSHIPS" domain
2. Verify category dropdown loads with categories
3. Select "Communication" category
4. Verify subcategory dropdown loads
5. Continue through all 4 levels

Test 4: Form Submission

1. Fill in all required fields
2. Submit form
3. Verify success message and reference number

Recommended Fixes

Fix 1: Load Domains on Page Load

Modify the JavaScript to load domains immediately when the page loads, not just when hospital changes:

$(document).ready(function() {
    // Load domains immediately on page load
    loadCategories(null);
    
    // Also load when hospital changes
    $('#id_hospital').on('change', function() {
        var hospitalId = $(this).val();
        loadCategories(hospitalId);
    });
});

Fix 2: Better Error Handling

Add error handling to the AJAX call:

$.ajax({
    url: loadCategoriesUrl,
    data: {hospital_id: hospitalId},
    success: function(data) {
        // ... existing code ...
    },
    error: function(xhr, status, error) {
        console.error('Error loading categories:', error);
        alert('Failed to load categories. Please try again.');
    }
});

Fix 3: Remove Console Logging

Remove or reduce console.log statements for production:

// console.log('Loaded categories:', data);  // Comment out or remove

Testing Script

A Python script to verify the API endpoint:

import requests
import json

# Test API endpoint
url = "http://localhost:8000/complaints/public/api/load-categories/"
response = requests.get(url)

if response.status_code == 200:
    data = response.json()
    print(f"✅ API returned {len(data['categories'])} categories")
    
    # Count by level
    levels = {}
    for cat in data['categories']:
        level = cat['level']
        levels[level] = levels.get(level, 0) + 1
    
    print("\nCategories by level:")
    for level, count in sorted(levels.items()):
        print(f"  Level {level}: {count} categories")
else:
    print(f"❌ API error: {response.status_code}")
    print(response.text)

Conclusion

The backend implementation is fully functional and working correctly. The API returns the complete 4-level taxonomy hierarchy as expected. The potential issue is in the frontend JavaScript which may not be loading the initial domain dropdown automatically when the page loads.

Next Steps:

1. Perform browser testing to confirm JavaScript behavior
2. Apply recommended fixes if issues are confirmed
3. Remove console.log statements for production
4. Add proper error handling
