How do I configure settings in Django?

To configure settings in Django, you need to edit the settings.py file in your project directory. What specific settings are you looking to change?

I want to set up the database settings for PostgreSQL.

You can set up PostgreSQL by modifying the DATABASES setting in settings.py. Here's an example:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': 'your_db_name',
        'USER': 'your_db_user',
        'PASSWORD': 'your_db_password',
        'HOST': 'localhost',
        'PORT': '5432',
    }
}

Make sure to install the psycopg2 package as well.

What about configuring allowed hosts?

You can configure allowed hosts by setting the ALLOWED_HOSTS variable in settings.py. For example:

ALLOWED_HOSTS = ['yourdomain.com', 'www.yourdomain.com']

This is important for security to prevent HTTP Host header attacks.

How can I manage different settings for development and production?

You can manage different settings by creating separate settings files for development and production, or by using environment variables to switch configurations based on the environment.
