What changes here, if any, will require re-baking posts with hashtags in them? Will any required re-baking happen automatically based on enabling this, or will there be an explicit migration step to rebake?

I just merged a rake task for this: https://github.com/discourse/discourse/pull/19876 bundle exec rake hashtags:mark_old_format_for_rebake

After enabling the feature I just ran rebake all posts through rails. [image] Rebake all posts?

I have a lot of posts, the vast majority of which won’t need to be touched. I was kind of hoping there would be a rebake-only-affected-posts ability, either explicit or implicit.

This feature is fresh out of the oven. There isn’t any built in ability to rebake all posts that have category/tag mentions included with it at this time. Will keep an ear to the ground here for what folks feel is necessary there and/or what solutions people come up with in the meantime.

What we want to rebake is all posts for which the cooked representation matches class="hashtag", as far as I can tell. I don’t think that rebake_match will help here because it matches the raw text, and there is no option for matching against cooked text in the existing rails tasks. So this will, I think, require actual coding, either in the rails console or in a new task.

Something like Post.where("cooked like '%class=\"hashtag\"%'").each do |p| p.rebake! end

Something very like that! I just successfully tested exactly that on my staging site. I was thinking about the delay option for the posts:rebake_match but probably it doesn’t matter. It is of course insisting on re-processing all the images on the affected posts, which is unnecessary, so an automated fix just for this might reasonably avoid that, but in the meantime there is a way forward. I might want to do this by reverse ordering and adding a delay if a site has a lot of affected posts.

@mcwumbly Now that 3.0 was announced with this as a headline feature, what would you think about a migration that only fixed up the text without reprocessing images, or alternatively that lets you rebake only the affected posts with a delay so it doesn’t clog queues with image re-processing?

@martin can you share a few thoughts here on how you might approach this problem? In short, I think what people want ideally is something like: when I turn on the new hashtag feature, I want a way to update the style of all my old hashtags to match, without otherwise changing the contents of existing posts And maybe also: when I turn it off, I want an easy way to do the opposite.

This is the usual pattern for rake tasks:

cd /var/discourse
./launcher enter app
bundle exec rake hashtags:mark_old_format_for_rebake
