Hi all, In my OrdersController, I have two actions completed and incomplete that respond_to HTML and CSV. Im also action caching these actions .. caches_action :completed, :incomplete ... def completed @orders = Order.completed respond_to do |format| format.html format.csv {render :layout => false} end end def incomplete @orders = Order.incomplete respond_to do |format| format.html format.csv {render :layout => false} end end Now the cached fragments when I go to the CSV urls are views/localhost:3001/orders/completed.csv views/localhost:3001/orders/incomplete.csv My sweepers have the following cache expiration commands .. expire_action :controller => :orders, :action => :completed, :format => :csv expire_action :controller => :orders, :action => :incomplete, :format => :csv ... But the log says Expired fragment : views/localhost:3001/completed.csv Expired fragment : views/localhost:3001/incomplete.csv notice that it missed "/orders" in there? The cache therefore never expires for the CSV format output. It works fine for HTML though. Any idea what im doing wrong?
