        schema_editor.execute(schema_editor.sql_delete_table % {
            'table': ','.join(tables)

        if options['seed'] is not None:
            if len(options['seed']) == 0:
                call_command('seed')
            else:
                call_command('seed', *options['seed'])

This commands add functionality to Django, when you need to drop all tables, then just migrate all the migrations.
It has an ability to run the database seeder after the migration.

You can follow this tutorial to add database seeder functionality to your Django.

You just need to place that code something like this.

---- app
-------- init.py
-------- management
------------ init.py
------------ commands
---------------- init.py
---------------- migratefresh.py
---------------- seed.py

Then, you can run it using command python manage.py migratefresh or with seeder python manage.py migratefresh --seed

Tested in Django 2.2

If you want another version called migraterefresh (un-apply all migrations), you can go to:
