Possible to run single Rails command on Heroku without 'heroku run console'?

I frequently need to run the command "Rails.cache.clear" on Heroku and the only way I have found to do it is to first run "heroku run console" and then run the command. Any way to do it in one step?

I think this is what you're looking for:

heroku run rails runner -e production Rails.cache.clear

If you don't set the environment, development will be used.

If it's a common task like clearing the cache, make a rake task.

This seems to work:

echo "Rails.cache.clear; exit" | heroku run console

Without the exit it seems to hang for some reason, at least for me.

Create a rake task with the command. For example a file lib/tasks/cache.rake

namespace :cache do
  desc 'Clear memcache'
  task :clear => :environment do
    Rails.cache.clear
  end
end

Then you can run the command

heroku run rake cache:clear
