如何在Rails 4.2中显示delayed_job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。

将作业列为：

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

我得到的详细信息是：

#<Delayed::Backend::ActiveRecord::Job id: 57, priority: 0, attempts: 0, handler: "--- !ruby/object:Delayed::PerformableMailernobject...", 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::PerformableMailernobject...", 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> 

有了以上数据，我可以显示id、优先级、尝试次数等；但在处理程序的情况下，有一个由object、method_name等组成的大字符串；如何在rails视图中显示此handler.object和handler.method_name？请帮助：

这是我的处理程序字符串：

Answer 1

这就是yaml格式。您需要按照以下方式对其进行解析以获得数据。

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 %>
