Flash not deleting with Redis/Memcache store

Rails
1

I’m a recent convert to Rails and I’m working on a new project using
Rails 2.3 (I’ll probably upgrade at some point when Rails 3 is in
production and had a chance to bake the .0 bugs out). I’m going to use
Redis anyway for caching important data, so I thought I’d use the
redis-store:

But it appears the flash messages aren’t going away when they’re
supposed to as discussed in this issue, which I haven’t gotten a
response on yet:

The gist is ActionController::Flash::FlashHash#sweep isn’t properly
detecting that a flash has been used when using either the Memcache or
Redis store for sessions.

So how do I delete them manually? I thought about just editing the
FlashHash class and forcing it to delete any flash keys without checking
the @used stuff. That would for sure delete the key, but I don’t know
enough about Rails internals to say whether that will have unintended
side effects.

Any advice on what I need to do here?

Thanks!

Hi,
I’ve fixed this issue in 0.3.8 by replacing the old implementation,
borrowed from rack.
Just config the gem:

config/environment.rb

config.gem “redis-store”

then configure as session store:

config/initializers/session_store.rb

ActionController::Base.session_store = :redis_session_store
