[web2py] Re: subforms / formsets / form cloning imprementation
I've been researching about this since my last post, and just to be clear, this is exactly what I need to do: http://railscasts.com/episodes/196-nested-model-form-part-1 (please watch minute 1:00 of this video). So I wonder if it is possible to use web2py to create nested forms such as django's formsets (https://docs.djangoproject.com/en/dev/topics/forms/formsets/) or Ruby on Rail's Active Record Nested Attributes (http://api.rubyonrails.org/classes/ActiveRecord/NestedAttributes/ClassMethods.html)?

Hi Christian, thanks for your reply! Your approach sounds interesting and it seems to be one of the best options with what's possible as for this moment. I have this page already implemented and working in php/javascript, but I'm searching for a new full featured framework exactly to avoid these kinds of ugly workarounds. I guess I'll either wait until web2py implements this, or I guess I'll have to decide between rails or django for this project. I'm not a python or ruby programmer (I program mostly in C/Perl/shell and php), so it doesn't really matter much to me. I read all of web2py's documentation and created a few demo projects and I enjoyed it very much. I wish I had the programming experience and knowledge to help web2py developers to implement this feature, as it seems lots of other people also need this (I've found MANY threads from people asking the same thing on this mailing list). Thanks again!

Perhaps it would be a nice feature to add to the smartgrid - in place ajax update / addition. So you'd just add a smartgrid to your form, and you can click 'add' and right in place you can add a new record to the grid / db.

Take a look at this - maybe it's similar to what you need... http://www.web2pyslices.com/slice/show/1432/insert-and-delete-ajax-show-process On Monday, January 7, 2013 12:02:01 AM UTC-7, Henrique Pantarotto wrote: Hello everybody!
