I don't know what ver of Django you're using by my version certainly
appears that it doesn't perform the way you say it does. i.e. it looks
like it does not allow "" for Integer fields.
from '/django/db/models/fields/__init__.py'
class IntegerField(Field):
empty_strings_allowed = False
Although, It's possible my 3min analysis of what empty_strings_allowed
does is wrong. You'd have to look closer at the above file but it looks
like overriding this
def get_db_prep_save(self, value):
"Returns field's value prepared for saving into a database."
return value
is what your after. I've not done this before though so "caveat
programmer".
btw, I really think IntegerField is the wrong column type for a zip
code. They can be upto 11 chars long and have hyphens. I'd make it
CharField or maybe even a USZipCodeField from
'contrib/localflavor/us/forms.py' There's many others in localflavor if
your flavor isn't US.
