Answer 1

I had this issue a while ago. The above answer maybe correct but it didnt work for me because -im using postgres, i cant just delete the database -migration files were commited in git.

My situation was, I have 004 migration file but i cant run it because of IntegrityError.

I checked the file, and i saw it was in operation list.

The first item of list is migrations.CreateModel and the second was migrations.AddField

here are my steps:

1. I commented the second item in list, only the CreateModel is remaining.

4. uncomment the AddField section and rerun the migrate.
