Django-cms: l'objet 'Settings' n'a pas d'attribut 'SITE_ID'

Question

Je souhaite activer mon instance de django-cms pour héberger plusieurs sites. Pour cela, j'ai créé deux sites différents dans le panneau d'administration.

Malheureusement, un seul site est affiché car je devais coder en dur le SITE_ID dans les paramètres du projet. Selon le https://github.com/django/django/pull/2460, ce paramètre n'est plus obligatoire. Mais mon Django 1.10.7 exemple montre le retraçage suivant si je le supprimer:

Answer 1

Je résolu à problème différemment. J'ai utilisé le plugin djangocms-multisite.

Je ne sais pas si c'est la meilleure solution mais ça marche.

Answer 2

On dirait SITE_ID est requis par Django CMS, il est dans le retraçage

File "/var/www/venv/lib/python3.5/site-packages/cms/utils/conf.py", line 294, in get_site_id 
    return settings.SITE_ID
