Django can't add a new field by itself without null values being allowed here, especially when you have unique=True set on this field. To solve that issue, you have to perform it in steps:
1. Add a column with null=True or without unique=True and with some default value 2. Make sure that all records in database will have a unique value. 3. Change the field to the final state.
