Hi @glebm , what version of iron_cache_rails are you using? The line numbers don't seem to much up.

[glebm]

Rails meta madness and ruby 2.0 sometimes don't play well with line numbers. I tried 1.4.0 and master (last week), both fail.

Looks like the Rails 4 interface has changed, made a pull request for it, any chance you could try that branch?
