Rails Devise send password reset mail as delayed job

Question

i want set the rails plugin devise'reset_password_instructions to delayed_job..but i tried many ways is fail.

i found a function password_controller#creat they have

self.resource = resource_class.send_reset_password_instructions(params[resource_name])

i think the sentence used for send email to reset password.

i want alter it like

self.resource =  Delayed::Job.enqueue ApplicationController::MailingJob.new(:resource_class.send_reset_password_instructions, params[resource_name])

ok, it will return Syntax error...

help me ..i don't know how to solve it..thx.
