Hi, Someone posted a widget for this, called "dynwidget" a little while back. I couldn't actually find it searching the archives just now, but I have the file here; mail me privately if you'd like it.
You mention in a later post you're fairly happy with the JavaScript side of this. The validation is actually very easy. DynWidget is an extension of a RepeatingFieldSet, which uses a ForEach validator. That validator does not need to know in advance how many rows you have - you get extendability out of the box. Saving the data back to the model is easy enough in this example of a single extendable form. I have a somewhat more complicated form that involves many growable fields, and two levels of nesting. I've coded an SQLAlchemy extension to help with saving this to the db. It's very hacky at the moment, but I am planning to eventually tidy it up and release it. Paul Chris Miles wrote: >Hi!
