HTML Rendering Enhancement for Snapshot Downloader ✅
🎨 ENHANCEMENT COMPLETED
The ParentZone Snapshot Downloader has been enhanced to properly render HTML content from the notes field instead of escaping it, providing rich text formatting in the generated reports.
📋 WHAT WAS CHANGED
Before Enhancement:
<!-- HTML was escaped -->
<div class="notes-content">
<p>Child showed <strong>excellent</strong> progress.</p>
<p><span style="color: rgb(255, 0, 0);">Important note</span></p>
</div>
After Enhancement:
<!-- HTML is properly rendered -->
<div class="notes-content">
<p>Child showed <strong>excellent</strong> progress.</p>
<p><span style="color: rgb(255, 0, 0);">Important note</span></p>
</div>
🔧 CODE CHANGES MADE
1. Modified HTML Escaping Logic
File: snapshot_downloader.py - Line 284
# BEFORE: HTML was escaped
content = html.escape(snapshot.get('notes', ''))
# AFTER: HTML is preserved for rendering
content = snapshot.get('notes', '') # Don't escape HTML in notes field
2. Enhanced CSS Styling
Added CSS rules for rich HTML content:
.snapshot-description .notes-content {
/* Container for HTML notes content */
word-wrap: break-word;
overflow-wrap: break-word;
}
.snapshot-description p {
margin-bottom: 10px;
line-height: 1.6;
}
.snapshot-description p:last-child {
margin-bottom: 0;
}
.snapshot-description br {
display: block;
margin: 10px 0;
content: " ";
}
.snapshot-description strong {
font-weight: bold;
color: #2c3e50;
}
.snapshot-description em {
font-style: italic;
color: #7f8c8d;
}
.snapshot-description span[style] {
/* Preserve inline styles from the notes HTML */
}
3. Updated HTML Template Structure
Changed from plain text to HTML container:
<!-- BEFORE -->
<div class="snapshot-description">
<p>escaped_content_here</p>
</div>
<!-- AFTER -->
<div class="snapshot-description">
<div class="notes-content">rendered_html_content_here</div>
</div>
