deliver_later using sidekiq rails

I tried to do deliver_later using sidekiq, but I got a error message.

Here is my setup

* execute redis
redis-server

* execute sidekiq
bundle exec sidekiq -q default -q mailers

* Gemfile
gem 'sidekiq'


* application.rb
config.active_job.queue_adapter = :sidekiq


#send email
UserMailer.account_activation(@user).deliver_later


I have no idea how to resolve the problem.
Here is error message

This is the error

2016-11-18T17:13:50.414Z 41513 TID-oxh5ccnb8 WARN: ActionView::Template::Error: No route matches :action=>"edit", :controller=>"account_activations", :email=>"chandleryang76@gmail.com", :id=>nil missing required keys: [:id]

Your mailer view is erroring out. Somewhere there you have something like this

edit_account_activation_path(@activation)


where @activation is nil. Hence the error. Edit path is not valid without an object.

@activation

There is error in mailer view.
You need to check @activation object which is passing as nil.

If you are working with sidekiq don't use deliver later because the job never performs, instead use perform_in(<>) and call a worker with the method deliver_now inside

config.active_job.queue_adapter = :sidekiq

I guess you follow the book《ruby on rails tutorial》, if we run the code with deliver_now, the result will correct, but if we run the code with deliver_later, the error top will show.
After reading active job guides, i know active job use GlobalID, which makes it possible to pass live Active Record objects to your job instead of class/id pairs.

In the book 《ruby on rails tutorial》, the attribute activation_token is virtual attribute

class User < ApplicationRecord
attr_accessor :activation_token
end


active job use user object as argument, user object will be sent as excepted, but the virtual attribute will lost, the methods are as follows:

class UserMailer < ApplicationMailer
def account_activation(user, activation_token)
@user = user
@activation_token = activation_token
mail to: user.email, subject: "user activation"
end
end

UserMailer.account_activation(user, user.activation_token).deliver_later

<p><%= link_to "active link", edit_account_activation_url(@activation_token, email: @user.email) %></p>
