Configuration options

Public user signup

By default, only administrators can create users, and the public signup facility is disabled. To enable it, set the environment variable THUNOR_SIGNUP_OPEN=True. Users can then create an account by visiting the URL /accounts/signup on your server. It is strongly recommended that you also set THUNOR_EMAIL_VERIFICATION=mandatory to require new users to verify their email addresses if your server will be publicly accessible (see Email server configuration).

Dataset access without login

By default, users will need to be logged in to access any dataset or tag labeled "Public". To enable anonymous access (i.e. without an account, or when logged out), set the THUNOR_LOGIN_REQUIRED environment variable to False.

Email server configuration

An email server is required to enable the THUNOR_EMAIL_VERIFICATION option. Enter the details of an SMTP server using the DJANGO_EMAIL_HOST, DJANGO_EMAIL_PORT etc. variables.

Integration with Sentry

Sentry is an error monitoring and aggregation system. For example, if an error occurs when a user loads a page on the site, the error will be logged in Sentry. Administrators can be alerted by email.

Sentry is available as a service (free for small use cases and academic use), or can be installed locally.

See the Sentry quickstart guide to create a project to track Thunor alerts. When you have a Sentry DSN (a URL to which software can report errors), set that value as the environment variable DJANGO_SENTRY_DSN to enable Thunor's Sentry integration.

Complete list of settings

Thunor Web is configured through the use of environment variables, which are listed below.

Remember to restart Thunor Web after changing configuration: python restart
