Manually cache the content in the key determined by path. Example:
cache_page "I'm the cached content", "/lists/show"
# File vendor/rails/actionpack/lib/action_controller/caching.rb, line 90 90: def cache_page(content, path) 91: return unless perform_caching 92: 93: benchmark "Cached page: #{page_cache_file(path)}" do 94: FileUtils.makedirs(File.dirname(page_cache_path(path))) 95: File.open(page_cache_path(path), "wb+") { |f| f.write(content) } 96: end 97: end
Caches the actions using the page-caching approach that‘ll store the cache in a path within the page_cache_directory that matches the triggering url.
# File vendor/rails/actionpack/lib/action_controller/caching.rb, line 101 101: def caches_page(*actions) 102: return unless perform_caching 103: actions = actions.map(&:to_s) 104: after_filter { |c| c.cache_page if actions.include?(c.action_name) } 105: end
Expires the page that was cached with the path as a key. Example:
expire_page "/lists/show"
# File vendor/rails/actionpack/lib/action_controller/caching.rb, line 80 80: def expire_page(path) 81: return unless perform_caching 82: 83: benchmark "Expired page: #{page_cache_file(path)}" do 84: File.delete(page_cache_path(path)) if File.exist?(page_cache_path(path)) 85: end 86: end
