This happens to me when I do the openedx pytest:

pytest openedx

RuntimeError: Model class openedx.core.djangoapps.content_staging.models.StagedContent doesn’t declare an explicit app_label and isn’t in an application in INSTALLED_APPS.

This error is similar to the one discussed in Django Installed Apps Error after Quickstart on M1 - could you please review that thread and see if any of the issues there are what’s causing it for you?

I’m encountering this error as well in my development environment. I have noticed that unlike content_tagging, the content_staging app is not explicitly added to the list of INSTALLED_APPS but rather is detected via the plugin_app configurations. I wonder if there is a reason in our local environments that the plugin is not getting registered correctly. I’m planning to rebuild the image and see if that helps. Will keep you posted.

I found my silly error. This content_staging app is only registered for the CMS environment, but I was in an LMS shell. When I switched into a shell within the CMS container, the errors went away. :man_facepalming:
