Rebake falha ao alterar apenas o nome do subdomínio

Olá

Recentemente, copiei a pasta do banco de dados /shared do nosso servidor de produção para o de staging (para que ambos os ambientes ficassem compatíveis).

Percebi que os links estavam apontando para o domínio anterior, então segui este guia.

Ao executar este comando dentro do container:

discourse remap forums.coretabs.net discourse.coretabs.net

Recebi um erro de duplicate key value:

Reescrevendo todas as ocorrências de forums.coretabs.net para discourse.coretabs.net
ESTA TAREFA VAI REESCREVER DADOS, TEM CERTEZA (digite SIM)
SIM
Erro: ERRO: valor de chave duplicada viola a restrição de unicidade "index_incoming_domains_on_name_and_https_and_port"
DETALHE: A chave (name, https, port)=(discourse.coretabs.net, t, 443) já existe.
O remap foi aplicado apenas parcialmente devido ao erro acima. Por favor, execute o script novamente.

Yeah I don’t think we have conflict handling built in and you have incoming links for both domains.

You are going to need to manually delete stuff from the problem table prior to running this task.

Thanks Sam for the fast reply!

Could you please point me to where I can manipulate the problematic table?

rails c
DB.exec "update from incoming_domains set name='discourse-old.coretabs.net' where name = 'discourse.coretabs.net'"

Is likely what you want it will lead to a minor data inconsistency but at least the remap will probably work.

So here is what I did:

  1. I run the command you pointed out (without from :grin:)

  2. Run the rebake again, now it stopped here:

Rewriting all occurences of forums.coretabs.net to discourse.coretabs.net
THIS TASK WILL REWRITE DATA, ARE YOU SURE (type YES)
YES
incoming_domains=1
incoming_referers=3
invites=1
javascript_caches=1
post_revisions=509
posts=84
single_sign_on_records=1099
theme_fields=4
topic_custom_fields=4
Error: ERROR:  duplicate key value violates unique constraint "unique_post_links"
DETAIL:  Key (topic_id, post_id, url)=(69, 212, https://discourse.coretabs.net/t/topic/365) already exists.
The remap has only been partially applied due to the error above. Please re-run the script again.

  1. Googled "unique_post_links" and found that its table is called topic_links from the schema.sql

  2. This time links are partial so I used a replace query:

DB.exec "update topic_links set url=REPLACE(url, 'discourse.coretabs.net', 'discourse-old.coretabs.net')"
  1. Run the rebake again.

Works like a charm, thanks Sam :rose:
