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?
