How does one create Widgets? This doesn't seem to be documented. Perhaps it's in The Book (I don't have it with me, and can't check). I'm a total novice at using Widgets in this way so pretty much everything you just said sounds like magic. I'm not at all sure how I'd do any of that. To be honest I'm got no problem creating the table or validating the data (which I'll do manually), just the idea of knowing how to generate unique inputs, and how to recognise them when they're submitted. > But that's a bit of a pain - I expect you just want to build your table > in the template, and insert the widgets as appropriate.

I think I'd be more inclined just to create an extra widget instance for each row, and send that down with the list of data. Is there a reason why I shouldn't do that? Surely there's more than 1 or 2 people who've implemented shopping carts or the like? :) -- Ben Sizer --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "TurboGears" group.
