Django unique, null and blank CharField giving 'already exists' error on Admin page

Question

I\'ve been getting the most weird error ever. I have a Person model

class Person(models.Model):
    user = models.OneToOneField(User, primary_key=True)
    f         


        

Answer 1

you are accepting blank values and expect them to be unique. this means there can only be ONE entry with a blank twitter_id

you can

• either remove the unique contraint
• remove the blank =True
• give a default value for the field ( but default needs to be unique)
