Creating an application

Now, let's create our first Django application. We will create a blog application from scratch. From the project's root directory, run the following command:

python manage.py startapp blog

This will create the basic structure of the application, which looks like this:

blog/
    __init__.py
    admin.py
    apps.py
    migrations/
        __init__.py
    models.py
    tests.py
    views.py

These files are as follows:

• admin.py: This is where you register models to include them in the Django administration site—using the Django admin 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: 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.
