Settings
The settings for the server are configured in the file numbasltiprovider/settings.py.
The first_setup.py script creates this file on installation.
You might want to change settings if you have a nonstandard environment, or after upgrading.
The Numbas LTI provider is a Django app, so many of the settings come from Django. See the Django documentation for information on these.
This page describes the available settings which are unique to the Numbas LTI provider.
