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 86 86: def cache_page(content, path) 87: return unless perform_caching 88: 89: benchmark "Cached page: #{page_cache_file(path)}" do 90: FileUtils.makedirs(File.dirname(page_cache_path(path))) 91: File.open(page_cache_path(path), "wb+") { |f| f.write(content) } 92: end 93: 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 97 97: def caches_page(*actions) 98: return unless perform_caching 99: actions.each do |action| 100: class_eval "after_filter { |c| c.cache_page if c.action_name == '#{action}' }" 101: end 102: 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 76 76: def expire_page(path) 77: return unless perform_caching 78: 79: benchmark "Expired page: #{page_cache_file(path)}" do 80: File.delete(page_cache_path(path)) if File.exists?(page_cache_path(path)) 81: end 82: end
