You are right.. changing it to the following throws a nasty syntax error.
<%= Rails.cache.fetch "all_catgory" do %> <!-- generate html for categories --> <% end %> If I do <% cache(:key => 'all_category') do %> <!-- generate html for categories --> <%end%> The it does work, BUT..somehow the page url is prepended to the cache key so essentially this fragment which is same across the app, misses for every new page load. [DEBUG 17-09-2010 12:06:37] Cached fragment hit: views/localhost/ categories/autos-motorcyles/vote_topics?key=all_category (0.4ms) [DEBUG 17-09-2010 12:06:37] Category Load (0.2ms) SELECT * FROM `categories` ORDER BY name ASC [DEBUG 17-09-2010 12:06:37] Cached fragment miss: views/localhost/ categories/autos-motorcyles/vote_topics?key=all_category (0.4ms) [DEBUG 17-09-2010 12:06:37] Rendered shared/_cat_nav_list (8.9ms) [DEBUG 17-09-2010 12:06:37] Cached fragment hit: views/localhost/ categories/autos-motorcyles/vote_topics?key=all_cities (0.3ms) [DEBUG 17-09-2010 12:06:37] User Load (0.1ms) SELECT distinct city FROM `users` [DEBUG 17-09-2010 12:06:37] Cached fragment miss: views/localhost/ categories/autos-motorcyles/vote_topics?key=all_cities (0.4ms) [DEBUG 17-09-2010 12:06:37] Rendered shared/_city_nav_list (4.7ms) Can someone please help!
