django.db.utils.IntegrityError: NOT NULL constraint failed: new__users_personal_detail.husband_adhaarcopy
this is how my models.py looks like.I have given blank=True and null=True for the file field as well,and i think i should have worked fine but when i run python manage.py migrate I get this error.
class Personal_Detail(models.Model):
beneficiary_adhaar_name=models.TextField(blank=True, null=True)
adhaarno=models.IntegerField(blank=True, null=True)
adhaarcopy = models.FileField(upload_to='adhaar/', null=True, blank=True,)
idcard=models.TextField(blank=True, null=True)
adhaar_eid=models.IntegerField(blank=True,null=True)
beneficiary_id_name=models.TextField(blank=True, null=True)
idno=models.IntegerField(blank=True, null=True)
idcopy=models.FileField(upload_to='identitycard/', null=True, blank=True,)
husband_adhaar_name=models.TextField(blank=True, null=True)
husband_adhaarno=models.IntegerField(blank=True, null=True)
husband_adhaarcopy = models.FileField(upload_to='adhaar/', null=True, blank=True,)
husband_idcard=models.TextField(blank=True, null=True)
husband_adhaar_eid=models.IntegerField(blank=True,null=True)
husband_id_name=models.TextField(blank=True, null=True)
husband_idno=models.IntegerField(blank=True, null=True)
husband_idcopy=models.FileField(upload_to='identitycard/', null=True, blank=True,)
def __str__(self):
return self.beneficiary_adhaar_name or self.beneficiary_id_name or str(self.pk)
First delete all the migrations in your migrations folder except init.py file and then run makemigrations
and migrate
commands.
hope it works
