• These files are as follows:

  • admin.py: This is where you register models to include them in the Django administration site—using this site is optional.
  • apps.py: This includes the main configuration of the blog application.
  • migrations: This directory will contain database migrations of your application. Migrations allow Django to track your model changes and synchronize the database accordingly.
  • models.py: This includes the data models of your application; all Django applications need to have a models.py file, but this file can be left empty.
  • tests.py: This is where you can add tests for your application.
  • views.py: The logic of your application goes here; each view receives an HTTP request, processes it, and returns a response.
