I’ve written an importer that pulls in a database of email addresses and Bios and sticks the bio into the About (aka `bio_raw`) field. It works fine, but the bios don’t show up because they aren’t getting baked. Inquiring minds want to know:
- Will a `posts:rebake` rebake them?
- Is there a way to rebake just the bios (and not 230K posts)?
- Is there a way to trigger the rebake in the importer script?
- If I’m patient will sidekiq notice?
- Is there a question I should have asked other than these?

Something like:
```ruby
users = UserProfile.where.not(bio_raw: nil)
users.each do |profile|
profile.recook_bio
profile.save
end
```

Thanks, @Falco. That’s the ticket!
Is there reason not to add
```plaintext
u.profile-recook_bio
u.profile.save
```
to my import script after
```
u.user_profile_update_column('bio_raw', the_imported_bio)
```
?
`update_column` updates the column without calling `profile.save`, which makes me wonder about `profile.save`, but there are lots of things I don’t understand yet. 🙂

From a brief read, `save` would cook for you.
In a import script I believe there’s a lot of concurrent work filling all your CPU cycles, so I would postpone something like `bio` to the final part.

Thanks for RTFMing the code for me. I still have trouble **finding** the code, but I’m getting there. 🙂
I think I see why to postpone the `save`. This script imports **only** bios, though, so I think in this case it’s probably fine to just stick it in this loop.
