Install django-parler via pip using the following command:

pip install django-parler==1.9.2

Edit the settings.py file of your project and add 'parler' to the INSTALLED_APPS setting as follows:

INSTALLED_APPS = [
    # ...
    'parler',
]

Also add the following code to your settings:

PARLER_LANGUAGES = {
    None: (
        {'code': 'en'},
        {'code': 'es'},
    ),
    'default': {
        'fallback': 'en',
        'hide_untranslated': False,
    }
}

This setting defines the available languages en and es for django-parler. We specify the default language en and we indicate that django-parler should not hide untranslated content.
