Show 6 most recent courses instead of featured courses on homepage

[Copilot]

Summary

Updated the homepage to display the 6 most recent published courses instead of the 3 courses marked as "featured". This change provides users with more current and diverse course options while simplifying the content curation process.

Changes

Backend (web/views.py)

• Modified the index view to fetch 6 most recent published courses ordered by created_at (descending)
• Removed the is_featured=True filter requirement
• Increased the limit from 3 to 6 courses

Before:

# Get featured courses
featured_courses = Course.objects.filter(status="published", is_featured=True).order_by("-created_at")[:3]

After:

# Get recent courses
featured_courses = Course.objects.filter(status="published").order_by("-created_at")[:6]

Frontend (web/templates/index.html)

• Updated section heading from "Featured Courses" to "Recent Courses"
• Removed the star icon (⭐) that indicated featured status
• Changed grid layout from 3 columns to 2 columns (md:grid-cols-3 → md:grid-cols-2) to better accommodate 6 courses in a 3×2 layout
• Updated empty state message for clarity

Testing (web/tests/test_views.py)

• Added comprehensive test test_index_shows_recent_courses() that:
  • Creates 8 published courses with different creation timestamps
  • Verifies exactly 6 courses are returned
  • Confirms courses are ordered by most recent first
  • Validates that featured status is no longer used as a filter

Screenshot

The homepage now displays "Recent Courses" with 6 most recent courses in a 2-column grid layout:

Testing

✅ All 20 existing tests pass - no regressions introduced
✅ New test validates the 6 most recent courses functionality

Benefits

• More courses visible: Users see 6 courses instead of 3, providing more learning options
• Always fresh content: Automatically shows the latest courses without manual curation
• Simpler maintenance: No need to manually mark courses as "featured"
• Better discoverability: Newer courses get immediate visibility on the homepage

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• install.python-poetry.org
  • Triggering command: curl -sSL REDACTED (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

Instead of Featured Courses on the homepage show 6 most recent ones
