Rails clear cache on heroku

Question

How can I clear the cache on Heroku?

I've tried heroku run rails c + Rails.cache.clear and receive the following error

Errno::ENOENT: No such file or directory @ dir_initialize - /app/tmp/cache/

I also tried heroku run rake tmp:clear (from this post). The task runs but when I go back into the console and run Rails.cache, nothing has changed.

How can I clear the cache?

Which cache do you want to clear? Do you have any cache enabled? — Simone Carletti, Aug 27 '15 at 14:31
@SimoneCarletti the application cache (so all cache, I think?). I'm getting some funky behavior after pushing new code and think flushing it will help. — user2954587, Aug 27 '15 at 14:48
What is the funky behavior. May be the issue is not related to the caching... — Simone Carletti, Aug 27 '15 at 15:48
@SimoneCarletti irregardless of the funky behavior I'd like to be able to flush the application cache — user2954587, Aug 28 '15 at 02:01

Did you try this? (This works with Celadon Cedar with the Heroku Toolbelt package at least)

heroku run --app YOUR_APP_NAME rails runner Rails.cache.clear

Update

If the above does not work, try running:

heroku run rake tmp:create
heroku run rake tmp:clear

yeh, same result `No such file or directory @ dir_initialize - /app/tmp/cache/ (Errno::ENOENT)` – user2954587 Aug 28 '15 at 14:10
@user2954587 please try the updated answer and let me know if that works! – K M Rakibul Islam Aug 28 '15 at 15:39
also, did you try: `heroku run rake cache:clear` command directly? rather from heroku console? – K M Rakibul Islam Aug 28 '15 at 15:46
