Um dos nossos moderadores alterou o carimbo de data/hora como uma forma de desbumpar um tópico, e eu quis reverter essa mudança. Então, escrevi uma tarefa rake que faz isso. É algo pequeno, mas por que não compartilhar?
# /var/www/discourse/lib/tasks/set_timestamp_to_last_version.rake
desc "Define o carimbo de data/hora de todas as postagens de um tópico como o last_version_at da postagem"
task "set_timestamp_to_last_version", [:topic_id] => :environment do |_, args|
topic_id = args[:topic_id]
if !topic_id
puts "ERRO: Esperado 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 "erro ao salvar postagem em #{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 "erro ao salvar postagem em #{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.
