This is a basic blog app.

Navigate to the project root directory and create an isolated environment with the following command: python3 -m venv my_env

This will create a my_env/ directory, including your Python environment. Any Python libraries you install while your virtual environment is active will go into the my_env/lib/python3.8/site-packages directory.

Run the following command to activate your virtual environment: source my_env/bin/activate

Run the following command at the shell prompt to install the dependencies with pip: pip install -r requirements.txt

If you are using Linux, install PostgreSQL with the following command: sudo apt-get install postgresql postgresql-contrib

If you are using macOS or Windows, download PostgreSQL from https://www.postgresql.org/download/ and install it.

You also need to install the psycopg2 PostgreSQL adapter for Python. Run the following command in the shell to install it: pip install psycopg2-binary==2.8.4

Create a user for your PostgreSQL database. Open the shell and run the following commands:

su postgres
createuser -dP blog

You will be prompted for a password for the new user. Enter the desired password and then create the blog database and give ownership to the blog user you just created with the following command: createdb -E utf8 -U blog blog

Then, edit the settings.py file of your project and modify the DATABASES setting to make it look as follows:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': 'blog',
        'USER': 'blog',
        'PASSWORD': '*****',
    }
}

Replace the preceding data with the database name and credentials for the user you created. The new database is empty. Run the following command to apply all database migrations: python manage.py migrate

Finally, create a superuser with the following command: python manage.py createsuperuser

You can now run the development server and access the administration site at http://127.0.0.1:8000/admin/ with the new superuser. python manage.py runserver
