Rename apps for a minimal project

Question

I'd like to rename myapp from block to article

1. change the app directory name from block to article
2. amend the installed apps in setting.py
3. amend it in app.py
4. delete migrations and make new

When I try to login admin site, it report

 ModuleNotFoundError: No module named 'article'

I found multiple answer to this question, but they are complicated than I simply re-start a new project.

Is it possible a straight-forwards solution.

The error report:

You can create a file named -'apps.py' in your app directory and set a different name in 'name' attribute for your app by inheriting django's 'AppConfig' class as follows -

from django.apps import AppConfig

class AppNameConfig(AppConfig): 
    name = 'new name'
    verbose_name = "new verbose name"
