(I'm spoiled: I'm replacing a pile of Perl code I wrote some years ago, and it did this. My users will at least ask about any functional regression, here.) It looks like DataMapper might make this easier than ActiveRecord. But I'm _this close_ to having something up and running, after pussy-footing around with this for almost a year, and I'm reluctant to tear out a bunch of stuff and start anything over, just to get auditing the way I want it. I could use some encouragement, specifically around not having to replace all my controller code (which is, alas, not very small or DRY) and the model validations I've got. Or I could just say "this person added/updated this object", possibly dumping all the values after save(), and leave it at that. But: Ick. Or read in the old object again (inside a transaction?) and do the comparison myself.

I'm in Safari right now, and I can't see any font that is too small. What resolution are you on? Hm, yeah, there are a couple bugs in Safari, like the size of the shadow to the box.

It'll be a very interesting library to watch over the next while. On an unrelated note, you might want to increase the size of your monospaced fonts. They're _really_ tiny in Safari.

I think this is going to get quite a bit of adoption. I can really see it being put into other projects like Sinatra etc. Thanks for the compliment! I’m really loving DataMapper myself.
