Page sweeping just got a whole lot easier! Rails only offers methods to expire a single page but no methods to expire an entire action or controller. This plugin does just that. This initial release of the plugin only adds one method (expire_each_page() ) to your disposal. Hereâ??s a quick example and exactly how it works. expire_each_page(:controller => 'pragmatic', :action => 'view') The above method will call url_for on the controller/action combo and expire all pages that are under public/pragmatic/view/ and public/pragmatic/view.html expire_each_page(:controller => 'pragmatic') The above method will call url_for on the controller and expire all pages that are under public/pragmatic/ and public/pragmatic.html To install this plugin just run: script/plugin install http://svn.recentrambles.com/broomstick SETUP INSTRUCTIONS Make sure that this broomstick directory in under your_app/vendor/plugins/ There are a couple of issues you will need to fix in your routes.rb and your .htaccess or lighttpd.conf if you want to use this plugin. First let fix your routes.rb. If your routes.rb has this line: map.connect '', :controller => "pragmatic" you will need to add this line directly above it: map.connect '/pragmatic', :controller => "pragmatic" map.connect '', :controller => "pragmatic" By adding the new line, you are telling rails to map all calls to url_for(:controller => â??pragmaticâ??) back to /pragmatic. Without this the exprire_each_page method will not work for your pragmatic controller (the controller that holds your initial action) because it is mapped back to â??/â??. This would cause the plugin to delete your entire public directory. Donâ??t worry, if you forgot to change this you will see a very nice long message in your logs and no files will be removed. The second issue is directly related to this routes.rb change. By adding this new map.connect statement, rails will stop caching an index.html page. It will start caching a pragmatic.html page. This works great but a new page will be created on each call because Apache is still looking for index.html. To fix this we modify the public/.htaccess file so that Apache will look for the pragmatic.html file instead of index.html. Here are the modified lines in the .htaccess file. This: RewriteRule ^$ index.html [QSA] changes to this: RewriteRule ^$ pragmatic.html [QSA] If you are using lighttpd add this line: url.rewrite = ( "^/$" => "pragmatic.html", "^([^.]+)$" => "$1.html" ) Thatâ??s all it takes to be able to do mass page expirations based on a controller and or action. Released under the same license as Ruby. No Support. No Warranty. Back up your public directory (or whatever you have your rails cache directory set to) before usingâ?¦I hope you already knew that!
