Django 1.8 Programming Error: Relation Auth_user Doesn't Exist When Running Test

I've read already the existing answer about this problem in Stackoverflow. But none worked for me. When I run manage.py test, I get the following, although my website run fine! $ .

Solution 1:

Your iobserve app doesn't have any migrations, and you can't have a relation, such as a OneToOneField, from an unmigrated app to a migrated app.

You need to run manage.py makemigrations iobserve to create the initial migrations for the iobserve app. Only when the initial migrations exist, will manage.py makemigrations without any app labels create new migrations for that app.
