managers – TARDIS Model Managers

ExperimentManager Objects

class tardis.tardis_portal.managers.ExperimentManager

Implements a custom manager for the Experiment model which checks the authorisation rules for the requesting user first

To make this work, the request must be passed to all class functions. The username and the group memberships are then resolved via the request.groups and request.user objects.

The tardis.tardis_portal.auth.AuthService is responsible for filling the request.groups object.
