Falha na reconstrução em db:migrate "relation "form_templates" already exists"

Suporte Instalação

A reconstrução do Discourse está falhando. Aqui está o log.

Qual é a melhor maneira de resolver isso? Temos o Postgres hospedado no RDS e executamos o Discourse com o método oficial de contêiner Docker.

Isso pode ser um bug. Mudei o assunto para fornecer um pouco mais de informação.

Quais plugins você tem instalados?

5

Como encontrar plugins?

6

algo como

cd /var/discourse
grep clone containers/*
7

Tentei encontrar o diretório de plugins e aqui estão os listados.

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

Não instalamos nada além de temas.

8

Você não tem um app.yml em algum lugar que é o que é lido quando você faz uma reconstrução?

Mas parece que minha ideia não vai explicar nada.

9

Encontrei o app.yml. Não há plugins extras listados lá. Como eu disse, tenho certeza de que não instalei nada além de temas.

Aqui estão os passos que demos e que levaram a este problema.

  • Tentamos mover todos os ativos para o S3 usando rake uploads:migrate_to_s3
  • O comando acima falhou dizendo que 155 de 161 ativos não foram movidos
  • Tentamos restaurar para a versão anterior usando “Rollback” no painel de backup
  • O site inteiro travou. Nada está funcionando.
  • Quando tentamos restaurar usando a linha de comando, ele diz que estamos tentando restaurar enquanto há migrações pendentes
  • Para executar as migrações, tentamos reconstruir, mas isso levou a este erro.

Espero que isso dê alguma ideia. A propósito, no momento, toda a nossa implantação está quebrada. Qual é a melhor saída para isso? Temos o backup mais recente feito no S3 antes de começarmos tudo isso.

10

O painel de backup do RDS? Provavelmente foi aí que você errou.

Se restaurar o backup mais recente estiver OK, então eu criaria um novo banco de dados, atualizaria o app.yml com o novo nome do banco de dados, certificaria que as configurações do S3 para o backup estão no arquivo yml, reconstruiria e restauraria.

Se você quiser resolver o problema com dinheiro, pode me contatar diretamente.

Não painel RDS, mas painel discourse.

Vamos tentar por algum tempo, mas se não funcionar, entraremos em contato em breve.

Banco de dados novo + máquina nova e restauração funcionaram bem. Obrigado pela resposta rápida.
