Por alguma razão, o Capistrano apaga todas as imagens no meu banco de dados toda vez que eu limito todas as imagens serem removidas de todos os usuários. Normalmente, o que eu fiz é reabastecer o banco de dados com as mesmas imagens que foram deletadas pelo Capistrano. Eu anexei meu arquivo deploy.rb, alguém pode me dar algumas dicas.
