Rails 3 caching: expire action for named route?

Use the regex version of expire_fragment : expire_fragment %r{render_c_t/#{c. Id}/}.

If you have cache on file_store, this is the best way to expire with RegEx – mikhailov Sep 14 at 1:52.

There should definitely be a more "Rails Way" to do this, but this might work as a back door: Rails.application.routes. Url_helpers will give you access to your helpers and each will return a string that's the path and/or url that would be sent to the browser in a Location header. Try Rails.application.routes.

Url_helpers. Render_ticker_for_channel_path(63) which should return /render_c_t/63 and Rails.application.routes. Url_helpers.

Render_ticker_for_channel(63, :host => 'mcr3. Dev') which should return http://mcr3. Dev/render_c_t/63 With some manipulation you could parse apart that second string to get back to the name that Rails is using for the cached action: def funky_action_cache_name(route, params) Rails.application.routes.

Url_helpers. Send(route. To_s+'_url', params).

Gsub(/https? :\/\//,'') end # expire_action(funky_action_cache_name(:render_ticker_for_channel, :id => 63)) Not the most beautiful solution, but should work!

Caches_action :render_ticker_for_channel, :if => proc do! Params'doCache' end But for this solution to work we need to pass an extra param either through query string or post body.

A Tar Heel is a couple of things. First, a student at the University of North Carolina, Chapel Second, any resident who claims North Carolina as home. It dates at least back to the Civil War and refers to the tar produced in that state which allegedly stuck to shoes.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
