"OperationalError: no such table: django_site" when running makemigrations with empty database when using Django-todo

Question

I have inherited a Django 1.11.6 application from another developer. Now after I have made a lot of changes to the code and data model, I want to re-create the sqlite database from scratch.

But when I run manage.py makemigrations in the project directory (no migration files and database present), I am getting the following error message:

C:\Django_DEV>python manage.py makemigrations --settings=mysite.settings_dev
Traceback (most recent call last):
  File "C:\Program Files (x86)\Python36-32\lib\site-packages\django\db\backends\utils.py", line 65, in execute
    return self.cursor.execute(sql, params)
  File "C:\Program Files (x86)\Python36-32\lib\site-packages\django\db\backends\sqlite3\base.py", line 328, in execute
    return Database.Cursor.execute(self, query, params)
sqlite3.OperationalError: no such table: django_site

The above exception was the direct cause of the following exception:

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

'django.contrib.sites' is present in the INSTALLED_APPS and there is a SITE_ID defined. Every solution I found on stackoverflow and other sources didn't fix the problem.

How can I get past this and continue developing the application with a empty database?

why do you have to do the makemigrations ? don't you have the migrations in your project ? Start by doing ```manage.py migrate```. Looks like you didn't apply the migrations of the installed apps from django — Bestasttung, Nov 12 '18 at 15:03
Yes that's right, but I got the same error when running `manage.py migrate`. The problem was caused by a bug in django-todo. — saxum, Nov 12 '18 at 15:19

The traceback shows that todo\utils.py is trying to fetch the current site from the database when the URL patterns are loaded:

  File "C:\Program Files (x86)\Python36-32\lib\site-packages\todo\utils.py", line 10, in <module>
current_site = Site.objects.get_current()

When this happens before you have run migrate for the first time, you get the error because the django_site table has not been created yet.

It looks as if the issue has been fixed in django-todo 2.0. If you can't upgrade, then as a hack you could temporarily comment out the django-todo urls.py or the current_site = Site.objects.get_current() line, so that you can run migrate.

I can't upgrade to 2.0 because it seems to be incompatible with django 1.11.6. But commenting out the todo urls did the trick! Thank you very much. – saxum Nov 12 '18 at 15:17
@F.Tamy for this question the problem was in django-todo, not in Django – Alasdair Oct 30 '20 at 20:13
@F.Tamy if you find you have to comment out your `urls.py` then there's probably some code imported by `urls.py` that needs to be modified. See [this recent question](https://stackoverflow.com/a/64643510/113962) for example. We're getting off topic here, this question and answer is definitely about a bug in Django-todo, not in Django. – Alasdair Nov 02 '20 at 10:15
@F.Tamy we're going round in circles here. I can't see your code or the full traceback, so I can't convince you that there's an issue in your project that you should fix. Running `makemigrations` won't ever solve the problem, you need to run `migrate` to create the table to stop the error. – Alasdair Nov 04 '20 at 09:14
@FedericoCapaldo this question and answer are about a specific bug in the `django-todo` app. I don't think your comment is related to that. Your problem will get more visibility if you ask a new question. – Alasdair Mar 17 '21 at 11:06
