Feature #671: Delete Confirmation Dialog on Dashboard

Overview

Implemented a delete confirmation dialog to prevent accidental deletion of product listings on the Farmer Dashboard.

Implementation Details

Location

  • File: frontend/src/pages/Dashboard.jsx
  • Component: Dashboard

Features Implemented

1. Delete Confirmation Dialog

  • Modal dialog appears when user clicks "Remove" button on a product
  • Displays product name in the confirmation message
  • Shows warning if product has open orders that may be affected
  • Prevents accidental deletion with explicit confirmation step

2. User Flow

  1. User clicks "Remove" button on a product listing
  2. handleDelete(id) function is triggered
  3. Confirmation dialog appears with:
    • Product name: "Delete {name}? This cannot be undone."
    • Warning message if open orders exist
    • Cancel button (closes dialog without deleting)
    • Confirm Delete button (proceeds with deletion)
  4. On confirmation, confirmDelete() calls API to delete product
  5. Dashboard reloads to reflect changes

3. Accessibility

  • Proper ARIA attributes:
    • role="dialog"
    • aria-modal="true"
    • aria-labelledby="delete-modal-title"
  • Keyboard support (Escape key closes dialog)
  • Focus management with ref

4. Open Orders Warning

  • Counts active orders for the product (status: pending, paid, processing, shipped)
  • Displays warning: "This product has X open order(s). Deleting it may affect buyers."
  • Helps farmers understand the impact of deletion

Code Structure

// State management
const [deleteConfirm, setDeleteConfirm] = useState(null);

// Trigger deletion flow
async function handleDelete(id) {
  const product = products.find(p => p.id === id);
  if (!product) return;
  const openOrders = sales.filter(o => 
    o.product_id === id && 
    ['pending', 'paid', 'processing', 'shipped'].includes(o.status)
  ).length;
  setDeleteConfirm({ id, name: product.name, openOrders });
}

// Confirm and execute deletion
async function confirmDelete() {
  if (!deleteConfirm) return;
  try {
    await api.deleteProduct(deleteConfirm.id);
    setDeleteConfirm(null);
    load();
  } catch { /* ignore */ }
}

Modal Dialog UI

  • Fixed position overlay with semi-transparent background
  • Centered white card with rounded corners
  • Clear typography hierarchy
  • Red delete button for destructive action
  • Gray cancel button for safe action

Testing

  • Test File: frontend/src/test/DashboardDeleteConfirm.test.jsx
  • Test Coverage:
    • Dialog appears when Remove button is clicked
    • Product name is displayed correctly
    • Cancel button closes dialog without deleting
    • Confirm button triggers deletion API call
    • Open orders warning is shown when applicable

API Integration

  • Endpoint: DELETE /products/:id
  • Client Method: api.deleteProduct(id)
  • Authentication: Required (farmer must own product)

User Experience Benefits

  1. Prevents Accidental Deletion: Explicit confirmation step
  2. Informed Decision: Shows product name and open orders
  3. Clear Consequences: Warning about affected buyers
  4. Easy Recovery: Cancel button available at any time
  5. Accessible: Works with keyboard and screen readers
