Model changes in Django

I made a mistake in the database definition When I changed DateField in Models.py to DurationField, an error occurred. So I took the method of recreating the database from scratch. Note. Be careful as the created User and other tables will also disappear. Note 2. There must be a way to change the database on Django, so use that if you can.

What i did

Erase all migration files
Delete database

Delete migration file

The file structure is as follows.

$ls
 -project -app -migrations
               Lviews.py etc.
          Lmanage.py
          Lconfig - settings.py etc.

$cd [Path to app]
$rm -d -r migrations/

Delete database

Delete sqlite file for sqlite I was using PostgreSQL, so I deleted the database directly from PdAdmin4 and recreated the database with the same name.
