When I try to change one of my models in the django admin I am getting the below error. Here is my model.
class Scan(models.Model):
image = models.FileField(upload_to = 'images/', default = 'images/')
R = models.IntegerField(255)
G = models.IntegerField(255)
B = models.IntegerField(255)
description = models.CharField(max_length=100)
user = models.ForeignKey(User, on_delete=models.CASCADE)
project = models.ForeignKey(Project,
on_delete=models.CASCADE,null=True)
clean = models.NullBooleanField(null=True, default= False)
