ActiveStorage::FileNotFoundError (ActiveStorage::FileNotFoundError) 在服务器日志中,但在控制台中不可重现

ActiveStorage::FileNotFoundError (ActiveStorage::FileNotFoundError) in server log, but not reproducable in console

我有以下型号:

class Section < ApplicationRecord
  has_many_attached :files
  def to_dir
    [client.to_dir, operation.to_dir, self.name.parameterize].join('/')
  end
  after_save :transload_files

  def transload_files
    TransloadService.sync( self.to_dir, self.files )
  end
end

transload_files 方法是问题所在。这是转载服务:

class TransloadService

    class << self

        def sync(check_dir, files)
            # First we have to check the transload dir for files that have been deleted on the app
            transloaded_files = Request.list(check_dir)
            cull_list = transloaded_files.reject{ |e| files.map{|t| t.filename }.include? Request.filename(e)}
            if cull_list.count > 0
                Request.trim(cull_list)
                p "#{cull_list.count} files trimed from #{check_dir}."
            end

            # Next we have to upload files which arent present in the transload dir

            send_list = files.reject{ |e| transloaded_files.map{|t| Request.filename(t) }.include? e.filename.to_s }
            if send_list.count > 0
                Request.upload_to(check_dir, send_list)
                p "#{send_list.map{|r| r.filename.to_s}.join(', ')} uploaded to #{check_dir}"
            end
        end

    end

end

这里是request.rb

中的相关代码
class Request
    class << self
        def upload_to(destination, files)
            files.each do |file|
                send_to = connection.object("#{destination}/#{file.filename}")
                file.open{ |tmp| send_to.upload_file(tmp) }
            end
        end
    end
end

我面临的问题是:当 after_save 回调 运行 是 transload_files 方法时 returns ActiveStorage::FileNotFoundError (ActiveStorage::FileNotFoundError)

当我在控制台中 运行 Section.last.transload_files 时,它完全按预期执行。我在这里错过了什么?

经过大约两天的实验,我得出的结论是,虽然创建了 ActiveStorage 记录,但它在任何模型回调中都不可用。官方 AS 文档引用了 after-create-commit 回调 here,但是我无法像包含的示例那样调用 blob.openblob.download。但是从控制台它可以工作。

我能够通过从 Section 模型调用作业然后从该作业调用传输服务来解决这个问题。

就我而言,我注意到在事务中使用 ActiveStorage 附加附件时无法正常工作。这适用于迁移或回调。
