Environment

• Python version: 3.4.3
• NetBox version: 2.2.0

Description

The NetBox WSGI service fails to start, returning the following error:

ImproperlyConfigured: Requested setting DATABASES, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

This issue has been traced to code intended to verify the PostgreSQL database version during initialization. However, the required settings variable is not available at the time of execution.

This issues does not affect the development server (manage.py runserver).

The logic which validates the PostgreSQL database version has been moved out of the main code and into the relevant migration (extras.0008_reports), which will run only when the migration is applied.
