Db:seed_fu falla en 002_groups.rb durante la actualización: Validación fallida: El nombre ya está en uso

Encontré un problema al actualizar desde v2026.3.0-latest. La tarea rake db:seed_fu falla al llegar a 002_groups.rb con el siguiente error:

ActiveRecord::RecordInvalid: Validation failed: Name has already been taken. (ActiveRecord::RecordInvalid)

La caída ocurre justo cuando el seeder intenta inicializar los nuevos grupos del sistema (ID 4: anonymous y ID 5: logged_in_users).

Lo confirmé mediante la consola de Rails. Ejecutar una verificación manual falla en la validación, pero omitir la validación permite que la base de datos guarde el registro sin problemas:

# Esto falla con «Name has already been taken»
g = Group.new(id: 4, name: "anonymous", automatic: true)
g.valid?

# Esto funciona perfectamente, lo que demuestra que no hay conflicto real
g.save(validate: false)

Pude superar este obstáculo creando manualmente estos nuevos grupos del sistema:

ActiveRecord::Base.transaction do
  g4 = Group.new(id: 4, name: "anonymous", automatic: true)
  g4.save(validate: false)

  g5 = Group.new(id: 5, name: "logged_in_users", automatic: true)
  g5.save(validate: false)
end

Ahora, al ejecutar rake db:seed_fu, se completa sin errores.

Pista de seguimiento completa:

# rake --trace db:seed_fu
** Invoke db:seed_fu (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute db:seed_fu

¿A dónde fue el botón “¡Yo también!”?

Esto ocurre cuando ya existe un grupo o un usuario (!!!) llamado anonymous.

Tenemos muchos foros donde anonymous se utilizó como nombre de usuario después de una importación.
El commit menciona:

Esta PR introduce dos nuevos grupos automáticos: anonymous_users y logged_in_users

pero al parecer el grupo finalmente se denominó anonymous sin el sufijo _users.

Es una lástima porque:

  • anonymous no deja claro si se trata de un grupo de usuarios o de un usuario individual
  • el riesgo de conflicto con un grupo o usuario existente es mucho mayor sin el sufijo _users

Soluciones sugeridas:
1 - nombrar al grupo anonymous_users como se planeó; así se alinea mejor con logged_in_users y reduce enormemente el riesgo de conflicto
2 - al menos detectar el conflicto y renombrar al usuario o grupo existente en lugar de generar un error
