Admin Evaluation Charts Fix - Complete Summary

Overview

Successfully fixed the ApexCharts rendering issue in the Admin Evaluation page and created test data for admin users with complaints and inquiries.

Issue Fixed

The admin evaluation page was experiencing a "t.put is not a function" error when ApexCharts tried to initialize on a hidden DOM element. This occurred because inquiry charts were being initialized while their tab was not visible.

Solution Implemented

1. Safe Chart Rendering Function

Created a renderChart() helper function that checks for DOM element existence before initializing charts:

function renderChart(elementId, options) {
    // Check if element exists and is visible
    const element = document.getElementById(elementId);
    if (!element) {
        console.warn(`Chart container ${elementId} not found`);
        return;
    }
    
    // Check if element is visible
    const style = window.getComputedStyle(element);
    if (style.display === 'none') {
        console.log(`Chart ${elementId} is hidden, skipping initialization`);
        return;
    }
    
    // Safe to render
    try {
        const chart = new ApexCharts(element, options);
        chart.render();
        return chart;
    } catch (error) {
        console.error(`Error rendering chart ${elementId}:`, error);
    }
}

2. Bootstrap Tab Event Listener

Added event listener for inquiry tab to render inquiry charts when the tab becomes visible:

document.addEventListener('DOMContentLoaded', function() {
    // Render complaint charts immediately (they're visible)
    renderChart('complaintSourceChart', complaintSourceOptions);
    renderChart('complaintStatusChart', complaintStatusOptions);
    renderChart('complaintActivationChart', complaintActivationOptions);
    renderChart('complaintResponseChart', complaintResponseOptions);
    
    // Set up tab event listener for inquiry charts
    const inquiriesTab = document.querySelector('[data-bs-target="#inquiries"]');
    if (inquiriesTab) {
        inquiriesTab.addEventListener('shown.bs.tab', function() {
            renderChart('inquiryStatusChart', inquiryStatusOptions);
            renderChart('inquiryResponseChart', inquiryResponseOptions);
        });
    }
});

Test Data Created

Management Command

The existing seed_admin_test_data command was used to create comprehensive test data:

python manage.py seed_admin_test_data --complaints-per-user 8 --inquiries-per-user 6

Admin Users Created

• Are assigned random complaints and inquiries with different:
  • Times (created over the last 90 days)
  • Severities (low, medium, high, critical)
  • Statuses (open, in_progress, resolved, closed)

Data Summary
