純粋な SQL で新しいユーザーを作成する方法

[paultaylor]

Discourseでユーザーを作成し、アクティブな状態として表示させるために、最低限どのテーブルに行を追加する必要がありますか？

私は user_emails テーブルに1行挿入しただけです。

insert into user_emails (user_id, email, "primary", created_at, updated_at) values (2,'user@email.com',true, now(), now());

予想通りGUIには表示されませんでしたが、最低限必要な手順は何でしょうか？さらに他のテーブルに追加する必要があるのか、それとも再起動が必要なのでしょうか？

おそらく「それは正しい方法ではない」と言われると思いますが、その点は理解しています。ただ、私にとっては以下の理由からこの方法が有効かもしれません（いくつかの前提が誤っている可能性もありますが、私の理解は以下の通りです）。

• 他のデータベースベースのフォーラムからデータをインポートするスクリプトは、Discourseインスタンスから元のフォーラムに接続できることを前提としています。しかし、ライブのDiscourseインスタンスから元のフォーラム（jforum）にアクセスするのは、困難か不可能でしょう。また、古いフォーラムが置かれている非常に古いサーバー上にDiscourseの開発環境を構築することも不可能です。
• Ruby on Railsの理解が乏しいため、既存のスクリプトを修正できませんが、SQLは理解できます。
• APIを利用することも可能ですが（ユーザー数は5,000人程度）、MD5パスワードハッシュを維持し、全ユーザーにパスワードリセットを強要したくないため、APIだけでは実現できないと考えています。
• jforum用のインポートスクリプトがあるため、jforumからデータを抽出するために必要なSQLを確認し、CSVファイルに変換してデータベースに読み込むことは可能です。
• バルクインポーターを使えばDiscourseにSQLを直接追加できるかもしれませんが、具体的なSQLが見つけられずにいます。
• ユーザーの移行が最も重要な課題であり、その後はカテゴリ、トピック、投稿の追加はそれほど難しくないはずです。

@paultaylor

ow I expect someone will say this is not the right ways to do things,

Right!

@paultaylor

and I understand that,

If you did, you’d not be asking.

The likelihood that you’ll end up with a corrupt database is pretty high. And then no one will be able to help you.

Dump your database and restore on your local Discourse server (or anywhere that it can connect to–I’ve done larger imports with a remote database over my home internet connection) and then run the existing script.

@paultaylor

dont understand Ruby on Rails so I cant modify the existing scripts, but I do understand SQL

It’ll be much easier to use Ruby that you don’t understand than to understand it well enough to figure out how to write the SQL. I learned Ruby a long time after I wrote my first importer.

[paultaylor]

@pfaffman

If you did, you’d not be asking.

That is a bit condesensing !
If the bulk import script is running sql (as I think it is)then documenting the SQL required to create a user is really no more dangerous then trying to use a bulk import script. And since I currently have a vanilla discourse install it wouldn’t terribly matter it if got messed up.I expect I have many more years in development than yourself.

What I don’t have great experience is all the admin tasks, and my first attempt to install a local Discourse server just opened a can of worms, and if I cant connect to my JForum mysql server from my discourse server then I’m going to have to install mysql as well and transfer the database. The existing jforum script isn’t checked into the main source tree, and Im on a very old version of jforum so not expecting it to work.

@paultaylor

That is a bit condescending!

I meant no offense. I guess you missed the ?

@paultaylor

I expect I have many more years in development than yourself.

I bet you’re right!

Sometimes free advice from someone that’s worked with Discourse full time for over three years, has done scores of imports, and written several importers from scratch is worth what you pay for it.

@paultaylor

connect to my JForum mysql server from my discourse server

How about setting up an SSH tunnel?

@pfaffman

a corrupt database

Inconsistent, maybe. Corrupt, no.

@paultaylor

want to be able to plugin/method that keep the md5 password hash rather than requiring all users to reset their passwords so I don’t think I can do this using the API

But you can create the users using the API and then insert the md5 hashes in a custom field using SQL. You will have best of both worlds.

Ooh! That’s a pretty great idea.

This is the free advice you’re looking for!

[paultaylor]

@michaeld

Yes, I had the thought but as I dont quite understand how the md5 hashing works wasn’t clear if that was possibility, okay I will give that a go.

[michaeld (Michael - Communiteq)]

必要なことは、カスタムフィールドを挿入するだけです：

• user_id：明らかなもの
• name: “import_pass”
• value: MD5 ダイジェスト

そして、migratepassword プラグインをインストールしてください。

[paultaylor]

ありがとうございます。いくつか質問がありますので、お手伝いいただけると幸いです。

インストール

Discourse ディレクトリで `bundle exec rake plugin:install repo=http://github.com/[Communiteq](https://www.communiteq.com) (formerly DiscourseHosting)/discourse-migratepassword` を実行してください
Discourse を再起動してください

1. インストールは完了しましたが、Discourse をどのように再起動すればよいでしょうか？

2. カスタムフィールドをどのように追加すればよいでしょうか？SQL 文を教えていただけますか？それとも、"user_fields[1]": "string" のような形式で API を使用して設定できますか？現在、API を使ってプログラム的にユーザーを作成することは可能ですが、このフィールドは現在無視しています。

3. プラグインがインストールされている場合、ユーザー作成 API リクエストで渡されるパスワードの値は無視されますか？

[michaeld (Michael - Communiteq)]

3. no, it will prevail over the md5 digest in the custom field.

The answers to the other two questions can easily be found on this forum. If you want to save time we can do the import and/or hosting for you as a paid service.

[paultaylor]

I did search for both answers, was unable to find. In the first case it is confusing that some installs are done via editing the yaml file and then relaunching the docker , and some seem such as this are installed whilst in the docker container, its not cxlear what restart means in this case.

I cant really find any pure sql in this forum

Surprised there seems such a push to sale paid services for using this opensrc software , never like this when i ask questions on stackoverflow.

[michaeld (Michael - Communiteq)]

I love to think along, innovate and contribute. But I also need to make a living and that means that I need to draw a line somewhere, and I try to draw it where I get the idea that I’m doing work instead of innovating, contributing and thinking along.

Looking up the SQL query for a user custom field is work for me, and as you’re an experienced dev I estimate that you can figure it out as well

[paultaylor]

@michaeld

Looking up the SQL query for a user custom field is work for me, and as you’re an experienced dev I estimate that you can figure it out as well

Well sure I can try and work it out but no harm in asking since its not

can easily be found on this forum

As for the other question, well it remains unclear to me.

I dont expect you to do my work for me, on the other hand side i do genrally find it frustrating how documentation assumes alot from users.

[paultaylor]

OK question 2, an example of adding a custom import_pass field for user_id 5, (user_id can be seen in the user_emails table or id from users table)

insert into user_custom_fields (user_id, name, value, created_at, updated_at) values (5,‘import_pass’,‘2aee1c40222c7754d4534e61452612cc’, now(), now());

@paultaylor

I have installed it, but how do I restart Discourse ?

Okay I found it
./launcher restart app
but doesnt seem to be restarting, I can enter app and connect to db, but cant connect to website. May just rebuild and start again

[paultaylor]

So I ran ./launcher rebuild app and now it is back and working.

I thought this would recreate the database but it has not so I guess that is because the actual database is persisting outside of docker and rebuild just rebuilds the docker app. Also I see the dataexplorer plugin I added (by modifying the yaml file is still there). But is the passwordmigration plugin there or does it get wiped out by rebuild, there is certainly nothing in the plugs in section of the adminpage.

Right I tried installing passwordmigration and then ran restart again, and once again my site is down, it does seem like passwordmigration is breaking something ?

So rebuilt again, got it working (but now passwordmigration plugin missing). If I run ./launcher restart app without installing migrationpassword first it restarts okay, so does seem to be a particular problem with migrationpassword on my setup

[pfaffman (Jay Pfaffman)]

Last time I tried, the passwordmigration plugin was incompatible with running an import, so you’ll want to install it after you do the import.

It could be that it’s breaking your rebuild, but that’d be fairly surprising, as Richard uses it in his hosting. I recommend that you install it in app.yml just as you did the data explorer after you’ve done your import.

rm -rf the postgres directories in /var/discourse/shared/standalone if you want to get a new database. Maybe have a look at Advanced Troubleshooting with Docker

[RGJ (Richard - Communiteq)]

@pfaffman

so you’ll want to install it after you do the import.

disabling it during the import should be sufficient

[paultaylor]

Weird, dropped database and ran ./discourse-setup so had a brand new install, everything fine.
Installed migrationpassword with rake and restarted, again website fails with 502 !
DataExplorer plugin still existed, so removed that, rebuilt, ok, then reinstalled migrationpassword and fails with 502 again.

So confusing because clearly works for others but doesn’t work on my vanilla install.

Will try to install via editing the app.yml file next.

[paultaylor]

（クリスマスショッピングのせいで遅れましたが）ついに app.yml を編集して再構築し、migratepassword のインストールを試みました…そして成功しました！
ただし、bundle exec rake plugin:install repo=http://github.com/[Communiteq](https://www.communiteq.com) (formerly DiscourseHosting)/discourse-migratepassword というオプションは、私のバニラインストールでは動作しません。おそらく、GitHub - communiteq/discourse-migratepassword: Support migrated password hashes · GitHub の README.md で確認または削除する必要があるかもしれません。
