Mailer unable to access reset_token in User model - ruby

Question

faced with an issue where #user.reset_token returns nil.
app/views/user_mailer/password_reset.html.erb
<%= link_to "Reset password", edit_password_reset_url(#user.reset_token, email: #user.email) %>
Reset_token is declared in User model, whereby this problem happens when I try to use a sidekiq worker. Refer to code below.
app/models/user.rb
class User < ActiveRecord::Base
attr_accessor :reset_token
def User.new_token
SecureRandom.urlsafe_base64
end
def send_password_reset_email
PasswordResetWorker.perform_async(self.id)
end
private
def create_reset_digest
self.reset_token = User.new_token
update_attribute(:reset_digest, User.digest(reset_token))
update_attribute(:reset_sent_at, Time.zone.now)
end
app/workers/password_reset_worker.rb
class PasswordResetWorker
include Sidekiq::Worker
sidekiq_options retry: false
def perform(user_id)
user = User.find(user_id)
UserMailer.password_reset(user).deliver
end
end
app/mailers/user_mailer.rb
class UserMailer < ActionMailer::Base
default from: "noreply#example.com"
def password_reset(user)
#user = user
mail to: user.email, subject: "Password Reset"
end
end
This problem DOES NOT happen when I do not use workers
app/models/user.rb
def send_password_reset_email
UserMailer.password_reset(self).deliver
end
Would like to know what can I replace "#user.reset_token" with? Let me know if you need more info. Thanks in advance.

You're not storing the reset_token in the database - you're storing the reset_digest.
When you don't use workers, you're storing the reset_token in the User instance, then passing that same User instance to your mailer - hence the reset_token is still available.
When you use workers, your worker only has the User's ID, so it's reloading the User instance from the database. Because the reset_token isn't being stored in the database, it's coming back nil.
Either you should be saving the reset_token in the database, or your password email should be using reset_digest in the URL.
