I had a topic with a poll and people voted it. This poll was eventually closed.
A few days later, the post content was edited and the poll was deleted. For 99% of cases, this does not delete the information in the polls table, but this time it appears that the info in that table is gone.
If I click on the edits icon, I can see that there is a post_revision with a poll in its content.
However, when I query the polls table I see that that day’s poll (311) has been deleted:
I would like to know two things:
-
Is there a reason why poll 311 was deleted but not 310 (previous day) or 312 (next day)? The same procedure was followed for all three polls: publish, let people vote, close the poll, edit the post and remove the poll from the contents.
-
Is there a simple way I can recover the poll information from a backup or do I have to create a temporary virtual machine, install Discourse there and restore the entire DB?
