django.db.utils.OperationalError：没有这样的表：django_site

Question

I am getting error when I am running python manage.py syncdb in django 1.7

I am using Python2.7 but I get the exact same error in Python 3.4.3

$ python manage.py syncdb

**django.db.utils.OperationalError: no such table: django_site**

Answer 1

I can see you are using django-CMS, I've encountered the same issue. I can assume that there might be an issue with newer versions of Django.

The root cause is that Django tables are not created yet, but cms tries to refer to them (in particular to get the current site from Sites framework)

That wasn't the issue in previous versions of Django because you would usually do python manage.py sycndb (which is removed at least in Django 1.9) and that command created all the django tables.

So to solve this - you need to comment out everything related to django CMS in your settings.py , run python manage.py migrate to migrate Django tables, and then uncomment cms stuff and migrate once again, then it shouldn't be an issue anymore. (sometimes it helps to also comment current project from installed apps as well as cms stuff so that Django 1.9 checks wont check your urls.py which has entries related to cms).

If you encounter the same issue on Django <1.9 but > 1.7 try to do syncdb first.

Hope that helps to anyone who encounters similar issue.

Answer 2

If it doesn't already exist, add the following to the INSTALLED_APPS property in settings.py:

'django.contrib.sites'

and also add SITE_ID = 1 in settings.py as well.

In Django 1.7+, the preferred way of making DB changes is with the migrate management command:

./manage.py migrate

That should solve your problem.
