Question

I would like to queue the method upload_to_scribd (from the gem scribd_fu) using delayed_job.

Is there any way I can do this without modifying the gem itself?

Answer 1

You shouldn’t have to do anything special to get this to work. For example, you can do probably do something like this:

ScribdFu.new.delay.upload_to_scribd

If you want you can also wrap this in a function or model of your own:

class Attachment
  def upload
    ScribdFu.new(self).upload_to_scribd
  end
end

Attachment.first.delay.upload

P.S: I don’t know if my syntax for the calls to the ScribdFu gem are correct, but you should be able to use the delay method in this way to queue the delayed job.

To accomplish what you want in your comment, create a file called (config/initializers/delay_scribd.rb) and add the following to it:

module ScribdFu
  module InstanceMethod
    handle_asynchronously :upload_to_scribd
  end
end

This will mean that any time this function is called it will be called in a delayed job, without having to explicitly call delay on the method.
