I forgot to add that I'm not doing any custom model validation as the
example in the documentation.
Here's the model in question:
class Person(models.Model):
person_code = models.CharField(max_length=50, unique=True, db_column
= 'code')
entered_by = models.ForeignKey(User, null=True,)
is_private = models.NullBooleanField(default=False, null=True,
blank=True)
entry_date = models.DateField(auto_now_add=True,)
fname = models.CharField('first name', max_length=100)
lname = models.CharField('last name', max_length=100)
#gender = models.CharField('gender', max_length=4, blank=True,
choices=GENDER_CHOICES,)
dob = models.DateField('date of birth')
dobestm = models.NullBooleanField(default=False, null=True,
blank=True,)
dobestd = models.NullBooleanField(default=False, null=True, blank =
True,)
dobBC = models.NullBooleanField(default=False, null=True, blank =
True,)
place_of_birth = models.CharField(max_length=100, blank=True,)
dod = models.DateField('date of death',null=True, blank=True,)
dodestm = models.NullBooleanField(default=False, null=True, blank =
True,)
dodestd = models.NullBooleanField(default=False, null=True, blank =
True,)
dodBC = models.NullBooleanField(default=False, null=True, blank =
True,)
cause_of_death = models.CharField(max_length=100, blank=True,)
#class Meta:
# db_table = 'trajectories_person'
def __unicode__(self):
return u'%s %s' % (self.fname, self.lname,)
