heya, Brenton: Thanks for the reply =).
Hmm, I was hoping to use the filter_horizontal widget to set the relationship, and just have a box below that for setting the rating. But you're right, we'd need a table for each rating for each relationship, and there's a room issue. I might look into extending the widget - is there any good documentation on extending Django admin widgets? I saw this article: http://www.fictitiousnonsense.com/archives/22 but I'm not sure if that's still up-to-date, and I was hoping for more details/examples to learn how to do it well. Any good reading recommendations on this topic? Also, it's not so much an issue with the inlines taking up space, as that the filter_horizontal widget, with the in-built search box, the "choose all" and "clear all" links is just a good UI, and looks quite nice, to boot. I'd really like to integrate it in somehow to the inline if possible...lol. Anyhow, finally, thanks for the tip about __self__, completely didn't think about that. Will set that now.
