如何在 Rails 4.2 中显示延迟作业日志中列出的数据？

Question

我正在使用delayed_job，并在一个页面中显示与该作业相关的所有信息。

将工作列为：

<% @jobs.each do |item| %>   
  <%= item.inspect %> 
<% end %>

我得到的详细信息如下：

#<Delayed::Backend::ActiveRecord::Job id: 57, priority: 0, attempts: 0, handler: "--- !ruby/object:Delayed::PerformableMailer\nobject...", last_error: nil, run_at: "2016-08-30 00:47:46", locked_at: nil, failed_at: nil, locked_by: nil, created_at: "2016-08-30 00:47:46", updated_at: "2016-08-30 00:47:46", queue: nil> #<Delayed::Backend::ActiveRecord::Job id: 55, priority: 0, attempts: 0, handler: "--- !ruby/object:Delayed::PerformableMailer\nobject...", last_error: nil, run_at: "2016-08-29 09:46:44", locked_at: nil, failed_at: nil, locked_by: nil, created_at: "2016-08-29 09:46:44", updated_at: "2016-08-29 09:46:44", queue: nil> 

通过以上数据，我可以显示 id、优先级、尝试次数等；但是在处理程序的情况下，有一个由对象、方法名等组成的大字符串； 如何在 rails 视图中显示这个 handler.object 和 handler.method_name？请帮忙：

这是我的处理程序字符串：

Answer 1

也就是yaml格式。您需要按如下方式解析它以获取数据。

job = Delayed::Job.last
data = YAML.load job.handler # parse the yaml
puts data.method_name #=> :welcome args
puts data.object #=> Delayed::PerformableMailer

你可以像这样迭代：

<% @jobs.each do |item| %>   
  <% data = YAML.load item.handler %> 
  <%= item.id %>
  <%= data.method_name %>
  <%= data.object %>
<% end %>
