Hi there,
can someone help me understand why the following code (posted also
here: http://dpaste.com/4867/) skips validation in clean_city entirely?
Am i not trapping the error correctly by evaluating against None?
I need to say that if a city is specified you can't specify a region or
a province... in other words either u specify a city OR you specify a
province OR you specify a region.
The application is a bug tracker for countries (in my case i want to
track down all Italian bugs so we'll have a Django scaling story to
tell too since they are way too many :) and these fields should help
define the *scope* of the bug.
Also a weird behavior is that if i specify all 3 fields city, province
and region only province and region get saved in the db.
Thanks,
Lorenzo
P.S I've just posted the essential code
