I figured this out myself when I was an account admin at a Canvas institution, and I have since seen it described in comments here on the community too, but I thought it might be good to formally commit this to words and pixels.
Sometimes an instructor chooses "Reset Course Content," not realizing the scope of its changes. They might think they need to reset their site to reuse it for a new term. Then they contact you, tearfully, with an empty shell where once stood their pride and joy.
If they are savvy, they might have tried the /undelete option before contacting you, but found nothing listed there to undelete. This is because, during a reset, Canvas doesn't really delete the course's content. It actually:
- deletes the course
- creates a new course shell and gives it the old course's name
- cross-lists the rosters from the deleted course to this new course shell
As a Canvas admin, I had two mantras. One was "Canvas really never throws anything away." (The other was "did you check the course start and end dates?" That's probably a topic for another, entirely different blog post, though.) So it's relatively easy to reverse this charge and make your instructor's day.
First you have to figure out the old course's Canvas course ID. You can get this a couple of ways:
- Examine the instructor's Canvas page views.
This will be really easy if they just performed the reset. If they did this a few days ago or otherwise engaged in Canvas after performing the reset, you might have a lot to scroll through. Searching for /settings/ can help you filter, since resets are performed from the course's Settings page.
EDITED TO ADD: Audra notes below that you can also pull this information from the Recently Deleted Courses report. - Search for the course name in your test or beta environment.
If there are too many page views to quickly identify the course, head to your test or beta environment. If the reset was triggered since Saturday, then the weekly or every-three-week sync will not have happened yet. You should be able to find the course either by searching for the course's title on your account's Courses page, or by searching for your instructor on the Users page and looking through the courses they are enrolled in.
Either way, you want the Canvas course ID, i.e. yoursite.instructure.com/courses/{this}, not the SIS ID for the course.
Head to your Canvas environment's Admin Tools page and undelete the course site.
Now the site is back, with its content. You can add the instructor back in their Teacher role and they're good to go after that. And, remember my mantra, "Canvas really never throws anything away?" You can cross-list the student rosters from the new site back to this undeleted site, and the students' submissions and gradebook will reappear too.
I hope this helps another admin down the road! Let me know in the comments if I forgot anything.
