Einer unserer Mods hat den Zeitstempel geändert, um ein Thema unbumpen zu können, und ich wollte diese Änderung rückgängig machen. Dafür habe ich eine Rake-Aufgabe geschrieben. Es ist zwar eine Kleinigkeit, aber warum nicht teilen?
# /var/www/discourse/lib/tasks/set_timestamp_to_last_version.rake
desc "Zeitstempel aller Beiträge in einem Thema auf die last_version_at des Beitrags setzen"
task "set_timestamp_to_last_version", [:topic_id] => :environment do |_, args|
topic_id = args[:topic_id]
if !topic_id
puts "FEHLER: Erwartet wird rake set_timestamp_to_last_version[topic_id]"
exit 1
end
Post.where(topic_id: topic_id).each do |p|
p.created_at = p.last_version_at
p.updated_at = p.last_version_at
if !p.save
puts "Fehler beim Speichern des Beitrags #{p.id}"
end
end
p_first = Post.where(topic_id: topic_id).first
p_last = Post.where(topic_id: topic_id).last
t = Topic.where(id: topic_id).first
t.created_at = p_first.last_version_at
t.updated_at = p_last.last_version_at
t.bumped_at = p_last.last_version_at
t.last_posted_at = p_last.last_version_at
if !t.save
puts "Fehler beim Speichern des Themas #{t.id}"
end
end
@zogstrip thoughts on pr-welcome? It’d be great for this to be on Github instead of needing to copy/paste from here if @yanokwa is willing to write one.
I only have a vague recollection of what went wrong, but I’ll try…
In Dec 2017, we accidentally moved our introductions topic (started in Jun 2017 and has daily posts) to Dec 2017. And it did what was expected in that it moved the first post to Dec 2017 and added the other posts sequentially. But it looked funny, in that all the posts had been squished into Dec 2017. I tried to move things back to Jun 2017, but then the squishing put al the posts into Jun 2017 instead of spreading them from Jun to Dec.
Again, this is what I think happened. Either way, I didn’t have time to figure it all out, so I wanted to restore the posts to their original date and when I poked around in the DB, this is what I came up with.
As far as things that would be good to add to the UI, I’d say:
If this squishing is reproducible, allow an undo of a timestamp change in the way I’ve done above.
