I am trying to display the next time an email is scheduled using any or all of the below arguments as inputs. I'm using resque, resque-scheduler and resque-mailer.
For example, above are the delayed jobs as displayed in the resque web interface. So I'd like to input "game_starting_reminder" and/or 226 and/or "Beat Box" and be able to then display the timestamp as such:
"Next scheduled email: 2017-10-31 at 9:30 pm".
However, when I try to call for the information in the console, the below is the output I receive
I've tried extending the delay_extensions and methods and using the find_delayed_selection method but that doesn't seem to work. For example this:
[18] pry(main)> Resque.find_delayed_selection { |job| job["class"] == QuizMailer}
TypeError: no implicit conversion of String into Integer
Or this:
[32] pry(main)> Resque.find_delayed_selection { {
[32] pry(main)* "class": "QuizMailer",
[32] pry(main)* "args": ["game_starting_reminder", [226, "Beat Box"]],
[32] pry(main)* "queue": "mailer"
[32] pry(main)* }}
=> ["{\"class\":\"QuizMailer\",\"args\":[\"game_starting_reminder\",[226,\"Beat Box\"]],\"queue\":\"mailer\"}",
"{\"class\":\"QuizMailer\",\"args\":[\"game_ending_reminder\",[226,\"Beat Box\"]],\"queue\":\"mailer\"}"]
Any other method I can use here? Or tips. Thank you!
Figured it out. The scheduled_at method is the best candidate here for the job.
First step is to add the DelayingExtensions module to the project. I just added the file from the resque source code on Github to initializers and then in resque.rb added the line:
#resque.rb
rails_root = ENV['RAILS_ROOT'] || File.dirname(__FILE__) + '/../..'
rails_env = ENV['RAILS_ENV'] || 'development'
resque_config = YAML.load_file(rails_root + '/config/resque.yml')
Resque.redis = resque_config[rails_env]
include DelayingExtensions
I modified the scheduled_at method from the github source code slightly because I couldn't get it to work as is and changed the name of the method to scheduled_for_time
#delaying_extensions.rb
def scheduled_for_time(klass, *args)
args = args[0]
search = encode(job_to_hash(klass, args))
redis.smembers("timestamps:#{search}").map do |key|
key.tr('delayed:', '').to_i
end
end
In this case, we can do the following in the console:
[2] pry(main)> klass =QuizMailer
=> QuizMailer
[4] pry(main)> args = ["game_starting_reminder", [230, "Beat Box"]]
=> ["game_starting_reminder", [230, "Beat Box"]]
[5] pry(main)> Resque.scheduled_for_time(QuizMailer, args)
=> [1515081600]
[6] pry(main)> Time.at(_.first)
=> 2018-01-04 21:30:00 +0530
Voila!
