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

Is there a reason why you don’t want to use ./launcher rebuild app? (Also, that looks like the dev environment’s bin/rails db:migrate command)

Try sudo -u postgres psql discourse? What are you trying to achieve with that, by the way? Adding context when looking for help is always appreciated.

zogstrip说的方法，我无法进入数据库 [图片] Migration error in 'rename_discourse_rewind_disabled_to_enabled' Self-hosting 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.

If you want to get to the database on a standard install, the way that I do it is ./launcher enter app su postgres psql discourse I’ve not seen bin/rails db, but when I ran it on one container (that uses an external database) I got a prompt asking for a password for user discourse.
