Hi,

I entered some products data into a table using a migration. I need to expire the page and fragment cache when I update, add, delete products from this table. I created a sweeper for this.

class ProductSweeper <  ActionController::Caching::Sweeper
  observe Product

  def after_create
    expire_cache
  end

  def after_save
    expire_cache
  end

  def after_update
    expire_cache
  end

  def after_destroy
    expire_cache
  end

  private
  def expire_cache
    expire_page(:controller => 'ProductsController', :action => 'index')
    expire_fragment 'listed_products'
  end
end

Then in script/console I update the product name and saved. When I reload my app in the browser it still gives me a cache hit.

Cached fragment hit: views/listed_products (0.2ms)

Can someone tell me how to expire this cache. I will not be adding, updating, deleting products through a controller action.

thanks, ash
