Hi,
I have been working for preparing a proposal about a new feature for
Django. I'm posting my draft proposal to Gist and want to know my idea
is OK or not. So I can proceed with the right approach. Any
suggestions or advice are welcome.
Abstract of my proposal:
* Automatically generate some simple javascript code to check the
validity for forms
* Many dynamic forms use similar logic, they can be abstracted into
a framework to help generated view code and javascript code, users
only need to fill out the logic of "how to change". Thus, the
workload of write dynamic form greatly reduced.

Hi,
Your proposal does have few points that I would like to address so you
could make your proposal more solid:
- What changes are required in Django core/forms to make this work? By
looking your current proposal it looks like something that can be done
without any changes to Django core/forms. This is actually your
"homework" that you have to do for proposal.
- You propose that this could be "django.contrib" package.That gives a
hint that this could be a 3rd party package. So it would be beneficial
that you actually do some reference implementation for example for few
fields to backup your proposal. If this requires some changes to core,
you can point them out in your proposal much easier.
- Django has a tradition to be agnostic from client side JS
frameworks. Your proposition states that validation would use jQuery.
What if I want to use something else like Dojotoolkit or ExtJS (which I
do use, I don't use jQuery at all).
- In your proposal Javascript is generated in a Python. It's generally
considered already a bad thing that forms makes certain rendering
designs HTML. Your proposal is to move more representation parts into
Python side. Could some of it be moved to presentation layer (templates)?
