• Camping: Return user to recent entries, but keep errors

  - by echoback

  Users can view a specific entry in my webapp with a URL. /entry/8, for example. If an entry doesn't exist, "Entry not found" gets appended to @messages and I render an error page. I'd like to redirect the user to /recent, but I can't figure out a good way to keep the error message around to be displayed. There are other actions that need to take place in the Recent controller, so I can't just duplicate the query and render :posts.
