Django error app engine deploy in standard env

Question

I'm trying to deploy a django app on google app engine using postgress, and i´m running out of ideas about what could be causing this error.

Everithing up perfect, but when i'm going to authenticate into django-admin, it throws me this error.

ProgrammingError at /admin/login/

relation "auth_user" does not exist
LINE 1: ...user"."is_active", "auth_user"."date_joined" FROM "auth_user...
                                                             ^

Already check the db access, setting file, migrations, and everything is setup correct.

Any ideas?

The "does not exist" ProgrammingError indicates that the your expectations and the database's reality are not aligned. Your changes might not be fully reflected in the database. Have you tried:

python manage.py makemigrations <app_name>

python manage.py migrate <app_name>
