-----------------------------------------
Summary: Defer instantiating output view providers until after
Django apps are ready
Key: AIRAVATA-3696
URL: https://issues.apache.org/jira/browse/AIRAVATA-3696
Project: Airavata
Issue Type: Bug
Components: Django Portal
Reporter: Marcus Christie
Assignee: Marcus Christie
Currently in settings.py all output view providers are instantiated. However,
they might import code that transitively imports Django models which is not
allowed in Django until all apps have been loaded (see
https://docs.djangoproject.com/en/3.2/ref/applications/#initialization-process).
A better approach would be to instantiate the output view providers in the
ApiConfig.ready().
