Description

I want to change my redmine to use memcached.
I do like http://www.redmineblog.com/page2 and redmine run faster than before.
But when I want to go to "Administration -> Settings" or "My Account" I get an "Redmine error 500".

config/additional_environment.rb

# config/additional_environment.rb
#
config.gem 'memcached' # For other hosts
# config.gem 'memcached-northscale', :lib => 'memcached' # For Heroku.com
require 'memcached'
config.cache_store = :mem_cache_store, ::Memcached::Rails.new('127.0.0.1:1121')

Try to clean your cache (rake tmp:cache:clear RAILS_ENV=production or similar)?

No, that doesn't help, just tried it out.
To me it looks like the i18n code within lib/redmine/i18n.rb, Line 95 got broken. Obviously this method does not work when you turn on memcached as cache store:

    # The result is cached to prevent from loading all translations files.
    def languages_options
      ActionController::Base.cache_store.fetch "i18n/languages_options" do
        valid_languages.map {|lang| [ll(lang.to_s, :general_lang_name), lang.to_s]}.sort {|x,y| x$
      end
    end

Unfortunately my rails knowledge is too limited to solve this, any idea what goes wrong?

Try to map Rails's Guide configuration rather thant the old blog one?

Or use Dalli since it's supposed to replace the memcached-client gem Rails uses by default.

Thanks Etienne!
That did it:
Changed config to

config.cache_store = :mem_cache_store, "127.0.0.1:1121"

and everything works as expected.

I will tell my colleague to close the ticket, maybe you could trigger an update for the blog entry.

I can't but I added his author as watcher if he wants to.

The blog entry is quite old now and was written with Redmine < 2.x so it shouldn't be used as a reference anymore.
