I have specified that my bio and image fields can be empty, but why does it give me an error and say that I have to fill it in?
class User_account(models.Model):
email = models.EmailField()
fullname = models.CharField(max_length=30)
username = models.CharField(max_length=20)
password = models.CharField(max_length=30)
marital_status = models.BooleanField(default=False)
bio = models.CharField(null=True, max_length=200)
visitor = models.IntegerField(default=0)
image = models.ImageField(null=True, upload_to='profile_img')
