我有一个动态调用邮件程序的方法，如下所示：

def mail
  application = mail[:application].capitalize
  class_template = mail[:template].split('/').[0]+ 'Mailer'
  template = mail[:template].split('/').second
  email_params = mail[:params].values.map(&:inspect).join(', ')

  "#{application}::#{class_template}.#{template}(#{email_params}).deliver_now"
   # Here I have something like : "Application::TemplatetMailer.test_name(\"John\", \"Doe\").deliver_now"
end

我怎么能有这样的东西：

Application::TemplatetMailer.test(\"John\", \"Doe\").deliver_now

代替

"Application::TemplatetMailer.test(\"John\", \"Doe\").deliver_now"
