Question

Let’s say I have this in my controller:

caches_action :my_action, :cache_path => Proc.new { |c| "my_action##{c.params}" }

Where the url is something like:

/w/:some_id/:additional_params

The caching works just fine, however I can’t find how to expire it.

I’ve tried:

expire_action(:controller => '/my_controller', :action => 'my_action')

expire_fragment(/my_action/)

store = ActionController::Base.cache_store
store.delete_matched(/my_action/)

But none is expiring my action. Any idea if it’s possible to expire a matching action like this?

Answer 1

From the comments at Caching docs you could add :expires_in option:

caches_action :my_action, :expires_in => 1.hour,
  :cache_path => Proc.new { |c| "my_action##{c.params}" }

Also, as you indicated, your URL-s are in the form of /w/:some_id/:additional_params so there is no my_action in the url. So you won’t match any objects with regexp /my_action/.

Probably this would expire cache:

expire_fragment(%r{/w/\d+/})
