运行bin/rails db 出现错误

[sniper756]

容器中以discourse用户运行bin/rails db 出现错误。已经重新安装Ubuntu，重新安装部署discourse，仍然出错。

[NateDhaliwal]

你是不想使用 ./launcher rebuild app 的原因吗？

（另外，那看起来像是开发环境的 bin/rails db:migrate 命令）

[sniper756]

查询数据库遇到的问题

Migration error in 'rename_discourse_rewind_disabled_to_enabled'

@here for those who are having issues, I think @david and I may have found the root cause but it’s complicated to reproduce locally. Could any of you run the following SQL queries and report the results here? Query #1 SELECT table_schema, column_name, column_default FROM information_schema.columns WHERE table_name = 'user_options' AND column_name = 'discourse_rewind_disabled' ORDER BY table_schema; Query #2 SELECT n.nspname, n.oid FROM pg_namespace n JOIN pg_class c ON c.relnamespace = n.o…

[sniper756]

./launcher rebuild app 没问题

[sniper756]

我找到查询discourse 数据库信息的方法了

1、进入容器

./launcher enter app

2、在容器里切到 postgres 用户并启动 psql

sudo -u postgres psql discourse

现在终端变成

discourse=#

3、看看有哪些表
\dt

4、退出 psql
\q

出现这个错误是正常的么？~~~~~~~

运行bin/rails db 出现错误

容器中以discourse用户运行bin/rails db 出现错误。已经重新安装Ubuntu，重新安装部署discourse，仍然出错。 discourse@jerry-app:~$ cd /var/www/discourse discourse@jerry-app:/var/www/discourse$ bin/rails db /usr/local/lib/ruby/gems/3.3.0/gems/bundler-2.6.4/lib/bundler/runtime.rb:71:in `rescue in block (2 levels) in require': There was an error while trying to load the gem 'debug/prelude'.

[Canapin (Coin-coin le Canapin)]

试试 sudo -u postgres psql discourse？

顺便问一下，你用这个想达到什么目的？在寻求帮助时提供背景信息总是很受欢迎的。

查询postgres数据库中的信息。

为下面这个帖子提供反馈

zogstrip说的方法，我无法进入数据库

Migration error in 'rename_discourse_rewind_disabled_to_enabled'

When inside the container, as the discourse user, at the root of the discourse directory, you can run bin/rails db to connect to the right db.

[pfaffman (Jay Pfaffman)]

如果你想在标准安装中访问数据库，我的做法是

./launcher enter app
su  postgres
psql discourse

我没有见过 bin/rails db，但当我（在一个使用外部数据库的容器上）运行它时，它会提示我输入用户 discourse 的密码。

[supermathie (Michael Brown)]

@pfaffman

我没有见过 bin/rails db

它是 rails dbconsole 的别名
