This worked for me. I thank my coworker for sharing this knowledge after I searched online for many hours.
Start your db shell
python manage.py dbshell
Use the database you want. If you don’t know, run .databases (SQLite) or SHOW databases
mysql>use <database_name>;
Retrieve all the migrations under your app
mysql> select * from django_migrations where app='<app>';
You will see the output with ids next to all migrations. You may want to drop the migration that was applied before its dependency: <appname>.0016_auto_<date2>_<time2>. Say its id is 361:
mysql> delete from django_migrations where id=361;
Now out of the db shell, run python manage.py migrate again.
