I added A Many2Many field in one of my forms and now I am getting an IntegrityError on submit. The exact error text is
IntegrityError at /add_person/ hireterm_person.mail_lists may not be NULL
It worked fine until I added the new field. When I look at the POST data on the debug change, I see it being passed, so I don't know where the break occurs.

class PersonForm(ModelForm):

class Meta:

EDIT
I added mail_lists = request.POST.getlist('mail_lists'). When I add a print to this, the list returned is all of the check boxes, put the POST data is still a single string, the last box checked.
