This is great, great, great - except for one thing: you can't nest forms inside other forms. While this will work fine for many cases, any time you want a button_to button inside an already existing form things will break in unfortunate ways. It's still worth having of course, but the rather nasty edge case needs to be documented. Simon Willison Simon Willison Simon Willison 2005-05-08 19:26:17.145 2005-05-08 19:26:17.078
