BrowserCMS can "delete" objects, which basically sets the :deleted attribute to true. Paperclip runs the following code initially to get all objects of a specific class: Person.connection.select_values(Person.send(:construct_finder_sql, :select => 'id')) This might return [1, 2, 3]. Even if, say, 3 has :deleted set to true. Paperclip ...

So Authlogic ships with some pretty confusingly (for an end user) named routes. For example, instead of /login/new, you get /user_session/new, and so on. Then, when a user can't login, the error message appears as "This user session could not be saved." It's a small thing, but that's just kind of... ugly, to me. What's a graceful way to...
