expire_action can expire by the custom path directly

[sishen]

expire_action can expire the custom path directly instead of passing :controller/:action for url generator.

For example,

caches_action :feed, :cache_path => proc do
    if params[:user_id]
      user_list_url(params[:user_id, params[:id])
    else
      list_url(params[:id])
    end
 end

So we can use expire_action(list_url(params[:id])) to expire the cache.

@sishen Is this still an issue?

@isaacsanders I think it should already be fixed by a pull request months later than mine. Thanks.

True. This code is already on master. Thanks.
