How to resolve the "psycopg2.errors.UndefinedTable: relation "auth_user" does not exist" when running django unittests on Travis
I ran into the same problem after adding a model for an app that was already installed, but forgetting to creating the initial migration. OP hid the answer in the comments so here are explicit steps:
$ mkdir myapp/migrations$ touch myapp/migrations/__init__.pyAfter this I got a new error when trying to run python manage.py test
psycopg2.errors.InvalidCursorName: cursor "_django_curs_140073820227328_58" does not existOne more step was needed:
$ python manage.py makemigrationsAnd then tests ran fine.
I deleted the sqllite3 database then I ran
$ python manage.py migrate then
$ python manage.py migrate --run-syncdb
The issue is that one of your apps is calling or referencing a non-existent model. The model may be in your code but no migration has been run for it.
Fix: Make sure all your apps have a migration package (i.e. migration folder with init.py file), then run makemigrations and migrate.
