Ruby on Rails Caching Page caching
Example
You can use the ActionPack page_caching gem to cache individual pages. This stores the result of one dynamic request as a static HTML file, which is served in place of the dynamic request on subsequent requests. The README contains full setup instructions. Once set up, use the caches_page class method in a controller to cache the result of an action:
class UsersController < ActionController::Base
caches_page :index
end
Use expire_page to force expiration of the cache by deleting the stored HTML file:
class UsersController < ActionController::Base
caches_page :index
def index
@users = User.all
end
def create
expire_page :action => :index
end
end
The syntax of expire_page mimics that of url_for and friends.
