It sounds like it.
And my vbulletin import script, which does handle non-linked attachments, doesn’t look for them in that table, so you’ll need some custom code to deal with that, even after I get around to submitting a PR with my script.
EDIT: and it also means that I think that even if they were linked in-post they still wouldn’t work, since they aren’t where the script expects them in the database.
Good news! I don’t know exactly how the import script handles it but it does! After making the files accessible to the import container and digging a bit in the script I found that it works. The only problem I had was that the file name which I tested it on contained an ä and thus some weird encoding shit prevented the script from finding the file actually. After fixing the filename the import worked and the attachment appeared at the post!
Thanks a lot for all the tips! 
Awesome! Glad the magic worked for you! (Oh! I and I see now that I was looking at the vBulletin script and not bbPress, hence my confusion. That explains why I couldn’t find the table!)
Hi
I got an error after launching the IMPORT bundle exec command:

Bundle complete! 130 Gemfile dependencies, 214 gems now installed.

Any idea please ?
Thank you 
このチュートリアルをありがとうございます、@vinothkannans さん！
bbpress.rb の修正でつまずいています。
sudo nano script/import_scripts/bbpress.rb を実行するとエディタが開くのですが、保存しようとしたら「そのようなファイルまたはディレクトリがありません」と表示されます：
これは完全に新規インストールです。
よろしくお願いいたします、
Jake
上記のガイドでは、Discourse 開発環境をインストールするために /var/discourse ディレクトリを使用しました。異なる場所にインストールした場合は、sudo nano script/import_scripts/bbpress.rb コマンドを実行する前に、上記の代わりにそのディレクトリ（ほとんどの場合 ~/discourse）に cd してください。
こんにちは、
/var/discourse フォルダに「script」パスが表示されません。
/var/discourse/scripts/ の状態は以下の通りです：
よろしくお願いいたします。
その通りです。
開発環境を設定するか、他のインポートに関するトピックに記載されている手順に従って、本番コンテナ内でインポートスクリプトを実行する方法を学ぶ必要があります。
欠落していた部分が見つかりました：Use an import script that requires MySQL
ありがとうございました。
@vinothkannans WPForoからDiscourseへの移行を試みていますが、スクリプト/コードが私の能力を超えています。どなたか手伝っていただけますか？よろしくお願いします。
Marketplace に投稿した方が良いかもしれません。このカテゴリを監視している人がたくさんいるので、手伝ってくれるはずです。
特定の移行に関する質問については、移行カテゴリもあります。
ガイドに従ってインポート スクリプトを実行しようとすると、次のエラーが発生します。これらの指示に従って Discourse をインストールしました。
