Steps I did: 1. Deleted migration files. 2.created only one initial migration file. 3. Enter psql command prompt. Connect to database. drop schema public cascade; create schema public; 4.tried to migrate again.
I get MigrationSchemaMissing(Unable to create the django_migrations table (%s) % exc) Error.

grant usage on schema public to username;
grant create on schema public to username;
