Configuration

This section describes any settings which are specific to iarbackend

Specifying the database

The default settings.py file contains a facility to configure the database by means of environment variables. A variable with a name of the form DJANGO_DB_<key> will be used to set the DATABASES['default'][<key>] setting. So, for example, one could set the location of the sqlite database by setting the DJANGO_DB_NAME environment variable or one could change the backend by setting DJANGO_DB_BACKEND.

Default settings

The default settings are given in the iarbackend.settings.base module:

iarbackend.settings.base.BASE_DIR = '/home/travis/build/uisautomation/iar-backend'

Base directory containing the project. Build paths inside the project via os.path.join(BASE_DIR, ...).

iarbackend.settings.base.SECRET_KEY = 'ex561uglj%!8oh*umt3-@2-4yj*&dc8cznob*vmb0!9bryoc-$'

The Django secret key is by default set from the environment. If omitted, a system check will complain.
