rails caching: expire_action in another namespace

Question

My application is using a namespace for administrative purposes. I recently tried to start using action caching however I ran into some problems trying to expire the cache u

Answer 1

One additional note I learned, if you want to expire a specific format, such as XML, JSON, etc., just

expire_action(:controller => '/newsposts', :action => 'index', :format => 'xml') 

or whatever format you want. It look me a while to figure out.

Answer 2

after some more digging I finally found the solution. It's a bit hinted in the url_for method:

In particular, a leading slash ensures no namespace is assumed. Thus, while url_for :controller => 'users' may resolve to Admin::UsersController if the current controller lives under that module, url_for :controller => '/users' ensures you link to ::UsersController no matter what.

So basically,

expire_action(:controller => '/newsposts', :action => 'index')

Will expire in the default namespace, and

expire_action(:controller => 'admin/newsposts', :action => 'index')

in the admin namespace (when in default).
