User 1 - * Posts
Posts can have various states, let's say 'DRAFT', 'LIVE', 'DELETED'.
Sometimes, we want to get all of the posts in existence for a user by doing:
user.all_posts
Sometimes, we just want to get posts that are not
Is there an obvious way to set up an association proxy so that it only
returns distinct objects?
For example, if I have:
Post - Tag - Tag_Category
and would like to access Post.Tag_Categories so that it contains each
category only once.
Any tips appreciated, sure I am missing something obvious

Any thoughts on how to track which call is leaving the connection open?

I've recently moved from SQLite to MySQL as the underlying database for my
application. The move is causing me various problems, principally around
Unicode. I *think* they were not occurring when SQLite was there, so I
thought I would ask if anybody on the list has had similar problems.
