So while investigating
https://meta.discourse.org/t/logout-menu-item/32731/21?u=cpradio
I enabled SSO, then logged out (yikes!), and now I can’t log back in, as it wants me to use SSO to do so 
How can I disable the enable_sso site setting so I can get back into my local environment?
in your /discourse
bundle exec rails c
SiteSetting.enable_sso = false
Ah, I did it a different route, but yours is easier. 
I ended up doing
s = SiteSetting.find_by(name: 'enable_sso')
s.value = 'f'
s.save!
I was just about to post that here and saw your response. Thanks! Now I can at least constantly get back to a good state between tests (or maybe I should setup an actual SSO…)
For future reference, visit /u/admin-login
Yeah just use /users/admin-login
Looks like you have no login methods available.
Do SiteSetting.enable_local_logins = true .
Yes!
Thank you very much!
After running : “bundle exec rails c”
I’m getting an error : “Could not locate Gemfile”
How to fix it?
Are you running this from inside your container (./launcher enter app)?
No I wasn’t 
since its wasn’t mentioned. Sorry a lot of things to learn yet 
So I did these commands:
cd /var/discourse
./launcher enter app
then
bundle exec rails c
and I’ve got the following errors:
URGENT: FATAL: Peer authentication failed for user “discourse”
Failed to initialize site default
/var/www/discourse/vendor/bundle/ruby/2.3.0/gems/activerecord-4.2.7.1/lib/active_record/connection_adapters/postgresql_adapter.rb:651:ininitialize': FATAL: Peer authentication failed for user "discourse" (PG::ConnectionBad) from /var/www/discourse/vendor/bundle/ruby/2.3.0/gems/activerecord-4.2.7.1/lib/active_record/connection_adapters/postgresql_adapter.rb:651:innew’

… many folders list

I did ./launcher rebuild app and tried again. The same errors!
After I’d pissed of these problems. I did restored my droplet from a previous snapshot I had and started from scratch.
I did enabled FORCE_HTTPS without a problem.
Can we change the discourse language in bundle exec rails c console?
How can we change the language of our site to english?
changing language can be done in database in site_settings column.
just search the current language and replace new language:
below code change language from Farsi to english:
UPDATE site_setting SET value = 'en' where value = 'fa_IR'
I have typed this code after typing : rails db
I had a problem with the force_https option (couldn’t login after enabling it). I fixed it by doing:
cd /var/discourse/
./launcher enter app
rails c
[1] pry(main)> SiteSetting.force_https = false
=> false
Creo que es necesario actualizar una expresión regular de configuración y quiero probar con un nuevo valor, pero cuando intento SiteSetting.key = value el sistema me bloquea debido a la expresión regular. ¿Existe alguna forma de forzar la actualización de un valor aunque no coincida con la expresión regular de la configuración?
Edición: esto funcionó, ¡pero ten mucho cuidado!
cd /var/discourse/
./launcher enter app
rails db
discourse=> update site_settings set value='newvalue' where name='settingname';
Luego sal y reinicia la aplicación:
./launcher stop app
./launcher start app
./launcher restart app es ligeramente más rápido para reiniciar la aplicación 
Por si acaso, aquí tienes una línea de comando en shell que no requiere reiniciar Discourse: bundle exec rails runner "SiteSetting.set('enable_sso', false)". Funciona exactamente igual que desde la interfaz de administración de Discourse.
