You should only need to set blank=true on your ModelForms fields:
models.py
class UserInfor(models.Model):
GENDERS = (
('nam', "Nam"),
('nữ', "Nữ"),
('khác', "Khác")
)
user = models.OneToOneField(User, on_delete=models.CASCADE)
date_of_birth = models.DateField(null=True, blank=true)
gender = models.CharField(choices=GENDERS, max_length=10, null=True, blank=true)
address = models.CharField(max_length=255, null=True, blank=true)
phone_number = models.CharField(max_length=10, null=True, blank=true)
def __str__(self):
return self.user.username
