How to convert string to YAML in Ruby 2.3.0? -

i using delayed_job in application , showing info jobs. ability show id , priority attributes couldn't show handler details.

in view, when try view details of job:

<% @jobs.each |item| %>      <% obj = yaml.load(item.to_yaml) %>   <%= obj.inspect %>  <% end %> 

when use inspect, getting details as:

#<delayed::backend::activerecord::job id: 51, priority: 0, attempts: 0, handler: "--- !ruby/object:delayed::performablemailer\nobject...", last_error: nil, run_at: "2016-08-25 19:56:44", locked_at: nil, failed_at: nil, locked_by: nil, created_at: "2016-08-25 19:56:44", updated_at: "2016-08-25 19:56:44", queue: nil> 

now need method_name handler, this, inorder list details, used

 <%= obj.handler.inspect %> 

it gave:

"--- !ruby/object:delayed::performablemailer\nobject: !ruby/class 'subscriptionnotifier'\nmethod_name: :welcome\nargs:\n- !ruby/object:user\n raw_attributes:\n deleted_at: \n name: espn star\n email: esp@test.com\n encrypted_password: \"$2a$10$jlv1bljcxpto4ithnkkvnoze.us6lmgdtkuvdniw4dftk8vzkx1os\"\n phone: ''\n website: ''\n designations: ''\n id: 22\n reset_password_token: \n reset_password_sent_at: \n remember_created_at: \n sign_in_count: '0'\n on

for showing method_name, think should make above string yaml, tried:

 <% obj = yaml.load(item.handler.to_yaml) %> 

no luck. please me how can convert yaml or how can show method_name?

i think should work:

<% @jobs.each |job| %>   <%= yaml.load(job.handler)["method_name"] %>  <% end %> 

as in job.handler yaml saved, can parse , access method_name [].
