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 83 83: def cache_page(content, path) 84: return unless perform_caching 85: FileUtils.makedirs(File.dirname(page_cache_path(path))) 86: File.open(page_cache_path(path), "w+") { |f| f.write(content) } 87: logger.info "Cached page: #{page_cache_file(path)}" unless logger.nil? 88: 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 92 92: def caches_page(*actions) 93: return unless perform_caching 94: actions.each do |action| 95: class_eval "after_filter { |c| c.cache_page if c.action_name == '#{action}' }" 96: end 97: 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 75 75: def expire_page(path) 76: return unless perform_caching 77: File.delete(page_cache_path(path)) if File.exists?(page_cache_path(path)) 78: logger.info "Expired page: #{page_cache_file(path)}" unless logger.nil? 79: end
