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/pages.rb, line 75 75: def cache_page(content, path) 76: return unless perform_caching 77: 78: benchmark "Cached page: #{page_cache_file(path)}" do 79: FileUtils.makedirs(File.dirname(page_cache_path(path))) 80: File.open(page_cache_path(path), "wb+") { |f| f.write(content) } 81: end 82: 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.
Usage:
# cache the index action caches_page :index # cache the index action except for JSON requests caches_page :index, :if => Proc.new { |c| !c.request.format.json? }
# File vendor/rails/actionpack/lib/action_controller/caching/pages.rb, line 94 94: def caches_page(*actions) 95: return unless perform_caching 96: options = actions.extract_options! 97: after_filter({:only => actions}.merge(options)) { |c| c.cache_page } 98: 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/pages.rb, line 65 65: def expire_page(path) 66: return unless perform_caching 67: 68: benchmark "Expired page: #{page_cache_file(path)}" do 69: File.delete(page_cache_path(path)) if File.exist?(page_cache_path(path)) 70: end 71: end
