This is how the accidental deletion occurred:
cd /var/discourse ./launcher enter app rails c Topic.where(:id=><id>).destroy_all
<id> I deleted was the wrong one and of course it just so happened to be a topic that a number of users were tuned into it. The important thing is I stopped, did not panic and did not execute another action after the accidental deletion occurred.
Stop, Do Not Panic and Do Not Execute
How I recovered the accidentally deleted topic using the rails console:
destroyed_topic = _ destroyed_topic.each do |destroyed_record| Topic.create(destroyed_record.attributes) end
For future reference are there other ways could I have achieved this? If so, how?
