Rebuild falla en db:migrate "la relación "form_templates" ya existe"

La reconstrucción de Discourse está fallando. Aquí está el registro.

¿Cuál es la mejor manera de resolverlo? Tenemos Postgres alojado en RDS y ejecutamos Discourse con el método oficial de contenedor Docker.

Esto podría ser un error. Cambié el asunto para proporcionar un poco más de información.

¿Qué complementos tienes instalados?

5

¿Cómo encontrar plugins?

6

algo como

cd /var/discourse
grep clone containers/*
7

Intenté encontrar el directorio de plugins y aquí están los que figuran.

chat	   discourse-details	  discourse-local-dates    discourse-presence  poll
checklist  discourse-lazy-videos  discourse-narrative-bot  docker_manager      styleguide

No instalamos nada excepto temas.

8

¿No tienes un app.yml en alguna parte que es lo que se lee cuando haces una reconstrucción?

Pero parece que mi idea no va a explicar nada.

9

Encontré app.yml. No hay plugins adicionales listados allí. Como dije, estoy seguro de que no instalé nada excepto temas.

Aquí están los pasos que seguimos y que llevaron a este problema.

  • Intentamos mover todos los activos a S3 usando rake uploads:migrate_to_s3
  • El comando anterior falló diciendo que 155 de 161 activos no se movieron
  • Intentamos restaurar a la versión anterior usando “Rollback” en el panel de copias de seguridad
  • Todo el sitio se bloqueó. Nada funciona.
  • Cuando intentamos restaurar usando la línea de comandos, dice que estamos intentando restaurar mientras hay migraciones pendientes
  • Para ejecutar migraciones, intentamos reconstruir, pero esto llevó a este error.

Espero que esto dé alguna idea. Por cierto, en este momento toda nuestra implementación está rota. ¿Cuál es la mejor manera de salir de esto? Tenemos la copia de seguridad más reciente tomada en S3 antes de que comenzáramos todo esto.

¿El panel de copias de seguridad de RDS? Probablemente ahí es donde te equivocaste.

Si restaurar la copia de seguridad más reciente está bien, entonces creo que crearía una nueva base de datos, actualizaría app.yml con el nuevo nombre de la base de datos, me aseguraría de que la configuración de S3 para la copia de seguridad esté en el archivo yml, reconstruiría y restauraría.

Si quieres tirar dinero al problema, puedes contactarme directamente.

No es el panel de RDS, sino el panel de Discourse.

Lo intentaremos durante algún tiempo, pero si no funciona, nos pondremos en contacto con usted en algún momento.

Base de datos nueva + máquina nueva y la restauración funcionó bien. Gracias por su pronta respuesta.
