Rails Caching
Use Rails caching to reduce response time and database load while keeping content fresh. This skill focuses on fragment caching, low-level caching, cache keys, and conditional GETs.
Fragment caching
Wrap view fragments that can be reused:
<% @products.each do |product| %>
<% cache product do %>
<%= render product %>
<% end %>
<% end %>
Notes:
- Cache keys include a template digest; edits to the fragment invalidate it.
