I am just beginning to look into using the delayed_job gem.
To test it, I added "delayed" to the welcome email function and changed that call from
UserMailer.welcome_email(self).deliver
to
UserMailer.delay.welcome_email(self)
This is called inside the User model after_create. I see an entry show up in the delayed_job table after the function executes. Now when I run "rake jobs:work" on command line the task starts but gives errors as below
[Worker(host:Sanjay-PC pid:7008)] Starting job worker
[Worker(host:Sanjay-PC pid:7008)] Class#welcome_email failed with NoMethodError: undefined method `welcome_email' for #<Class:0x4871d60> - 0 failed attempts
[Worker(host:Sanjay-PC pid:7008)] 1 jobs processed at 0.0939 j/s, 1 failed ...
Thinking that if I changed the welcome_email method declaration to a Class method as
def self.welcome_email(user)
(added self. in front) that might help. But then when I run rake jobs:work I get the following error
rake aborted!
undefined method `welcome_email' for class `UserMailer'

It seems to now know the class as UserMailer but it somehow doesn't see the class method welcome_email.
I am on Rails 3.0.5, Ruby 1.9.2p180 and the installed delayed_job gem is 2.1.4 - on Windows
Can't seem to find any related answers anywhere.
Thanks for your thoughts.

Adding UserMailer code per #pjammer's request
class UserMailer < ActionMailer::Base
default :from => "from#example.com"
def welcome_email(user)
#user = user
#url = "http://example.com/login"
mail(:to => user.email,
:subject => "Welcome to My Awesome Site")
end
end
Just use this
UserMailer.delay.welcome_email(self).deliver
instead of
UserMailer.welcome_email(self).delay.deliver
My solution was to redefine function at the handler class (for you it's UserMailer class)
def self.taguri
'tag:ruby.yaml.org,2002:class'
end
It's a hack and I'll try to find a better solution but now it works for me.
(Rails 3.0.9, Ruby 1.9.2-p290, delayed_job 2.1.4)
https://groups.google.com/forum/?fromgroups=#!topic/delayed_job/_gvIcbXrOaE solved my handles_asynchronously error for class methods.
As per Brandon Keeper in the link above, the code is the following:
class ClassName
class << self
def foo
end
handle_asynchronously :foo
end
end
then use ClassName.delay.foo

Had been in the process of getting a Rails Engine upgraded to Rails 5.1 and now in the process of getting the rspec tests back working.
I have a controller, and in that controller I have the following:
module Users
class SessionsController < Devise::SessionsController
skip_before_action :authenticate_user!
skip_before_action :authorize_user!
def create
super
flash[:analytics] = { "data-analytics-form-completed-name" => "#{StewardshipUser.app_slug}/sign-in", "data-analytics-form-completed-type" => "login" }
end
def repopulate_email
(params[:user] && params[:user][:email]) ? params[:user][:email] : ''
end
helper_method :repopulate_email
end
end
If I remove the skip_before_action :authorize_user! the tests run, but not all successfully.
With the line I'm getting the following error:
An error occurred while loading ./spec/validators/rfc_compliant_validator_spec.rb.
Failure/Error: Dummy::Application.initialize!
RuntimeError:
can't modify frozen Array
# /Users/ahcarpenter/.rvm/gems/ruby-2.2.2/gems/railties-5.1.4/lib/rails/engine.rb:579:in `unshift'
# /Users/ahcarpenter/.rvm/gems/ruby-2.2.2/gems/railties-5.1.4/lib/rails/engine.rb:579:in `block in <class:Engine>'
Any thoughts on why the initializer would be breaking down with that line in there?
Additionally, when I had initially gone to reinitialize rspec, I had to comment out that method to get the initializer to run as it was not found any longer for some reason (I don't seem to have bumped any gem versions up that contained that method, but maybe so)
I'm sure you've fixed this by now, but I had this error, I realized that my test database was not initialized properly. I fixed the error by running the following command:
rails db:migrate RAILS_ENV=test
I hope this is helpful for anyone who stumbles across this post.
My application was sending mails in background in development but recently i installed redis and resque to use resque along with resque-mailer and now nothing is working.Everytime i get a message RuntimeError Invalid delivery method :resque.I have been trying hard to figure out whats wrong because earlier i just included resque-mailer in user_mailer.rb and thats it,my mails were running but now i dont know what wrong i did.below are my relevant file AFTER INSTALLING REDIS using Railscasts for resque.I googled alot to find but many times i came across monkey patching devise but i dont think i need to do that as my mailers were working fine without worrying about devise.Using ruby 1.9.3 and rails 3.2
im getting same error when tried with sidekiq :(
my gemfile.
gem 'resque','1.19.0' ,:require => "resque/server"
gem 'resque_mailer'
my user_mailer.rb
class UserMailer < ActionMailer::Base
include Resque::Mailer
default from: "support#mywebsite.com"
def logged_in(user.id)
Rails.logger.info 'sending mail----------registeration mail----------'
#user=User.find(user_id)
p #user
###line number 19 is below
mail(:to => #user.email, :subject => " Hi #{#user.username},You logged-in just now ")
end
app/controllers/users/devise/sessions_controller.rb
##enqueue the mailer using resque and send mail asynchronously
###this was working earlier but now its not so i made use of railscasts above to use redis
###UserMailer.logged_in(resource.id).deliver
#user_id=resource.id
Resque.enqueue(UserMailerWorker,#user_id)
now the changes that i did using Railscasts and mail is not sending giving above error
my worker
class UserMailerWorker
#queue = :user_mailer_job_queue
def self.perform(user_id)
p 'usermailer worker sending logged in mail----'
p user_id
UserMailer.logged_in(user_id).deliver

well after removing and resetting my application...i came to know why i was getting this error.its because i was not starting the resque job as well as redis.so after starting redis using redis-server and resque using bundle exec rake resque:work QUEUE='*'...my asynchronous mail started working without any problem just by including include Resque::Mailer
I am getting the following error while executing SampleController.
uninitialized constant IdeasController::Delayed
I have already started the delayed_job by using rake jobs:work. I have the following delayed_job code in SampleController.rb
Delayed::Job.enqueue(DelayedWorker.new({:model=>object.class.to_s,:object_id=>object.id,:meth=>:create_suggestion}))
delayed_worker.rb contains the following code:
class DelayedWorker < Struct.new(:options)
def perform
if obj=Object.const_get(options[:model]).find(options[:object_id])
if (options[:para] ? obj.send(options[:meth],options[:para].first) : obj.send(options[:meth]))
puts "Successfull"
else
puts "Failed"
end
end
end
end
Any one please help me for resolving this.
Thanks...
Change
Delayed::Job.enqueue(DelayedWorker.new({:model=>object.class.to_s,:object_id=>object.id,:meth=>:create_suggestion}))
to
::Delayed::Job.enqueue(DelayedWorker.new({:model=>object.class.to_s,:object_id=>object.id,:meth=>:create_suggestion}))
I'm having trouble calling methods from an included module inside a resque worker. In the example below, I keep getting undefined method errrors when I attempt to call the say method inside the worker (which is in the TestLib module). I've reduced the code down to bare basics to illustrate the issue:
Controller
(/app/controllers/test_controller.rb)
class TestController < ApplicationController
def testque
Resque.enqueue( TestWorker, "HI" )
end
end
Library
(/lib/test_lib.rb)
module TestLib
def say( word )
puts word
end
end
Worker
(/workers/test_worker.rb)
require 'test_lib'
class TestWorker
include TestLib
#queue = :test_queue
def self.perform( word )
say( word ) #returns: undefined method 'say' for TestWorker:Class
TestLib::say( word ) #returns: undefined method 'say' for TestLib::Module
end
end
Rakefile
(resque.rake)
require "resque/tasks"
task "resque:setup" => :environment
I'm running resque using the following command: rake environment resque:work QUEUE='*'
Gems:
rails (3.0.4)
redis (2.2.2)
redis-namespace (1.0.3)
resque (1.19.0)
Server:
nginx/1.0.6
Anyone have any ideas as to what's going on there?
When you include a module, its methods become instance methods. When you extend, they become class methods. You just need to change include TestLib to extend TestLib and it should work.
I'm using the delayed_job gem here: https://github.com/collectiveidea/delayed_job
I have the following in an observer:
UserMailer.delay.msg_notification(record)
In user_mailer.rb
class UserMailer < ActionMailer::Base
...
def msg_notification(record)
mail(
:to => "#{record.user.email}",
:subject => "Notification"
)
end
..
end
But this errors with:
NoMethodError (undefined method `delay' for UserMailer:Class):
Any ideas? thanks
I've seen a problem like this on our Rails app (2.3.8, but the issue sounds the same). Basically, there are three ways to delay an action:
MyClass.delay.foo(arg)
Putting handle_asynchronously :foo in your class definition after the definition of foo
MyClass.send_later(:foo, arg)
For whatever reason, #3 was the only form that worked consistently across all our development machines. #1 died on our development server (Ubuntu); #2 on our designer's Mac. But #3 was fine.
Hope that helps!
Also check if you have restarted your server after the bundle install. That could be a issue too...
