你好，
我一直在尝试卸载 Akismet 反垃圾插件，因为它似乎不符合《通用数据保护条例》（RGPD）的要求；根据我们法律团队的分析，将数据在海外服务器进行分析在 RGPD 框架下似乎是非法的。
无论如何，我已经按照说明尝试卸载该插件，并执行了以下步骤：
1. 在论坛设置中停用该插件，
2. 使用 `./launcher enter app` 连接到 Docker 容器，
3. 运行命令 `bundle exec rake akismet_uninstall:delete_reviewables`，
4. 收到以下错误信息：
```plaintext
root@forum:/var/www/discourse# bundle exec rake akismet_uninstall:delete_reviewables
rake aborted!
ActiveRecord::NoDatabaseError: 我们找不到您的数据库：discourse。该数据库的配置信息位于 config/database.yml 文件中。
要解决此问题：
- 您是否已为该应用创建数据库，或者是否已删除它？您可能需要重新创建数据库。
- 数据库名称是否已更改？请检查您的 database.yml 配置中是否包含正确的数据库名称。
要创建数据库，请运行：
bin/rails db:create

我该如何让该插件使用 Discourse 数据库？

嘿 @nono-lqdn，
看起来这与您的实例配置有关。您能使用 `bundle exec rails c` 打开控制台吗？
您可以尝试在那里直接调用任务代码作为一种变通方法。
