Problems with database after cloning Django app from Github
The django_sessions table should get initialized when you run your first migrations. You said taht you made your migrations, but did you run them (with python manage.py migrate). Also, do you have django.contrib.auth in the installed_apps in your settings file? This is the app that owns that session table
I have just cloned a Django app from Github to a local directory. I know for a fact that the app works because I've run it on others' computers. 
When I run the server, I can see the site and register for an account. This works fine (I get a confirmation email). But then my login information causes an error because the DB appears to not have configured properly on my machine. I get the following errors: 
/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages/django/db/backends/utils.py in execute
                return self.cursor.execute(sql, params) ...
▶ Local vars
/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages/django/db/backends/sqlite3/base.py in execute
        return Database.Cursor.execute(self, query, params) ...
▶ Local vars
The above exception (no such table: django_session) was the direct cause of the following exception:
(It then lists a bunch of problems with local vars). 
I tried making migrations with every part of the app but this didn't appear to fix anything.
