def webcomic unless read_fragment({}) @comic = Comic.find(params[:id]) end rescue @comic = Comic.find(:first, :order => 'id desc') end end Since we haven t yet modified our sweepers to clean up our fragment caches, we should clear out our existing cache by running rake tmp:cache:clear from the root of our application. Once any existing cached fragments are removed, we can retest our fragment caching by refreshing the home page again. We can monitor the logs to see that our request to the page produced the same results but now it also caches the fragment: Processing PublicController#index (for 127.0.0.1 at 2007-05-28 22:07:57) [GET] Session ID: 06304d6bb8a857c0084d7702ce11b6a8 Parameters: {"action"=>"index", "controller"=>"public"} Fragment read: localhost:3000/ (0.00013) Comic Load (0.000522) SELECT * FROM comics ORDER BY id desc LIMIT 1 Rendering layoutfalsetemplatepublic/webcomic within layouts/application Rendering public/webcomic Fragment read: localhost:3000/ (0.00015) SQL (0.000250) SELECT count(*) AS count_all FROM comics Cached fragment: localhost:3000/ (0.00054) Completed in 0.00971 (103 reqs/sec) | Rendering: 0.00505 (51%) | DB: 0.00077 (7%) | 200 OK [http://localhost/] Now, if we refresh the page again, we should no longer see any requests to the database in our logs, as the read_fragment method detects the existing cache and prevents any unnecessary database hits: Processing PublicController#index (for 127.0.0.1 at 2007-05-28 22:08:05) [GET] Session ID: 06304d6bb8a857c0084d7702ce11b6a8 Parameters: {"action"=>"index", "controller"=>"public"} Fragment read: localhost:3000/ (0.00012) Rendering layoutfalsetemplatepublic/webcomic within layouts/application Rendering public/webcomic Fragment read: localhost:3000/ (0.00013) Completed in 0.00290 (345 reqs/sec) | Rendering: 0.00128 (44%) | 200 OK [http://localhost/]

It should come as no surprise that modifying our fragment cache is just a simple matter of changing the expire_page commands in our comic sweeper to expire_fragment commands instead: private def expire_cache_for(record) prev_version = (record.id - 1) expire_fragment(:controller => 'public', :action => 'index') expire_fragment(:controller => 'public', :action => 'webcomic', :id => record.id) expire_fragment(:controller => 'public', :action => 'webcomic', :id => prev_version) end After those changes, if we make a modification to one of the comics (such as changing its name), we can see our fragments being expired: Processing ComicsController#update (for 127.0.0.1 at 2007-05-28 22:24:23) [PUT] Session ID: 6d22fd6a722d8a707d6803ed16df0539 Parameters: {"commit"=>"Update", "_method"=>"put", "action"=>"update", "id"=>"2", "controller"=>"comics", "comic"=>{"title"=>"Chunky Bacon", "description"=>"Chunky Bacon"}} Comic Load (0.000303) SELECT * FROM comics WHERE (comics."id" = 2) Comic Update (0.000455) UPDATE comics SET "content_type" = 'image/jpeg', "size" = 325742, "height" = 650, "title" = 'Chunky Bacon, "filename" = 'comic.jpg', "width" = 647, "description" = 'Chunky Bacon' WHERE "id" = 2 Expired fragment: localhost:3000/ (0.00148) Expired fragment: localhost:3000/comic/2 (0.00023) Expired fragment: localhost:3000/comic/1 (0.00016) Redirected to http://localhost:3000/admin/comics/2 Completed in 0.14893 (6 reqs/sec) | DB: 0.00076 (0%) | 302 Found [http://localhost/admin/comics/2] With that, we ve effectively implemented fragment caching and simplified our application by reducing duplication. Go ahead and delete the sessions controller and its related routes, templates, and so forth now, since they ll no longer be of any use to us.

This is almost ready to go, but you ve reached the point where CocoaPlayer is losing its orthogonality. The images and colors used really depend on the specific game being played. You could pass in lists of tiles when you create the player, but as you go on, the number of customizations will keep getting larger. Instead, let s create a subclass of CocoaPlayer named DinoCocoaPlayer. Any gamespecific code or data can go into DinoCocoaPlayer. A lot of that data can be easily stored in class constants. Unfortunately, code in CocoaPlayer won t be able to see constants belonging to the subclass, even when the subclass inherits the code. This is a pain, but you can get around it with the following little dance. Add the following methods:
