I understand how many questions there are for this matter but none of the solutions suggested helped. I got the following problem: I deleted my models and deleted the imports in admin.py as well. Then I wanted to update the django database with makemigrations which shows that it deletes the model employee but then after using migrate command I saw an error that the relation does not exist. I also dropped it from the postgres database that I used. The strange thing here is that migrate keeps looking for the model which does not exists. Even if I create another one makemigrations detects it and then migrate says relation project_employee.. Tried syncdb --all no success. here is the output of migrate

Apply all migrations: sessions, project, admin, auth, contenttypes

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

Thank you

What helped finally was deleting the whole migrations folder from the project's folder. Saw some south responses as well, but haven't tried.
