Caching with Ruby on Rails

The code is from talk I gave titled "Real World Caching". You can see the see the slides here.

• Fragment Caching
  • Simple / Naive demo at http://localhost:3000/posts/simple_cached_index
  • Time based expiration at http://localhost:3000/posts/time_based_cached_index
  • Expiration based on Model changes at http://localhost:3000/posts/update_time_based_cache_index
• Russian Doll Caching
  • Multiple instances at http://localhost:3000/topics
  • Single model instance at http://localhost:3000/topics
• API example based on Model changes at http://localhost:3000/api/products.json
• API example based on changes for multiple Models at http://localhost:3000/api/products_and_posts_by_date.json
• Conditional GET example with clientside polling at http://localhost:3000/

Running locally

bundle install
rake db:create && rake db:seed
foreman start

Redis Dependency

This requires Redis in development for caching.

On Mac OS, install with brew install redis

Run with foreman start to start both redis-server and rails server.
