Cuando intento actualizar de 2.3.2 a 2.3.6, veo este error:

I, [2019-12-02T07:43:47.773465 #1]  INFO -- : > cd /var/www/discourse && su discourse -c 'bundle exec rake db:migrate'
rake aborted!

Si desactivo el plugin discourse-assign, todo funciona correctamente…
¡Pero! Un mes después actualicé otro foro de Discourse de 2.3.2 a 2.3.6 y todo pasó sin problemas…
¿Qué estoy haciendo mal?
Intenté:

cd /var/discourse
git pull
./launcher rebuild app

As you have diagnosed, the problem is with the discord assign plugin. (do you mean discord assign?)

Here is the guilty one:
20191119174425_rename_site_setting_assign_emailer.rb

Contains:

# frozen_string_literal: true

class RenameSiteSettingAssignEmailer < ActiveRecord::Migration[6.0]
  def up
    execute "UPDATE site_settings
             SET name = 'assign_mailer', value = '#{AssignMailer.levels[:always]}', data_type = #{SiteSettings::TypeSup
ervisor.types[:enum]}
             WHERE name = 'assign_mailer_enabled' AND value = 't' AND data_type = #{SiteSettings::TypeSupervisor.types[
:enum]}"

    execute "UPDATE site_settings
             SET name = 'assign_mailer', value = '#{AssignMailer.levels[:never]}', data_type = #{SiteSettings::TypeSupe
rvisor.types[:enum]}
             WHERE name = 'assign_mailer_enabled' AND value = 'f' AND data_type = #{SiteSettings::TypeSupervisor.types[
:enum]}"
  end

  def down
    raise ActiveRecord::IrreversibleMigration
  end
end

How can i fix this? If I fix it directly in this file, will the repository be downloaded again when the rebuild starts and my changes will be erased?

Solution:

  1. comment discourse-assing plugin in app.yml
  2. rebuild app with ./launcher rebuild app
  3. go to inside container ./launcher enter app
  4. cd /var/www/discourse/plugins
  5. git clone https://github.com/discourse/discourse-assign.git
  6. go to cd /var/www/discourse/plugins/discourse-assign/db/migrate
  7. edit file 20191119174425_rename_site_setting_assign_emailer.rb, replace ActiveRecord::Migration[6.0] to ActiveRecord::Migration[5.2]
  8. save file and exit from editor
  9. go to cd /var/www/discourse
  10. run su discourse -c 'bundle exec rake db:migrate'
  11. exit from container
  12. uncomment discourse-assign plugin in app.yml
  13. rebuild app AGAIN with ./launcher rebuild app
  14. TA-DA-DA-TAM! All works!

I have no decent words to describe this process! )))))))))

Thanks for reporting the issue @nahimov, it should now be fixed without needing the workaround you described
