  @queue = :create_site_map
  def self.perform(slct_common_path, http_host, site_id)
  end

require "resque/tasks"
require "resque/scheduler/tasks"

namespace :create_site_map do
  desc "Create site map"

  task create_site_map: :environment do
    Resque.enqueue CreateSiteMap, 0, "a", 1071

Resque.enqueue_to(:high, CreateSiteMap, 0, "abc", 1071)

or:

Resque.enqueue(CreateSiteMap)

it's show error like this: wrong number of arguments (given 0, expected 3) pls help me How can I pass arguments in resque?

Answer 1

By looking at the code here

https://github.com/resque/resque/blob/master/lib/resque.rb#L386

It seems like, if you are using enqueue, you should pass the class name and the parameters

# https://github.com/resque/resque/blob/master/lib/resque.rb#L402
def enqueue(klass, *args)
  enqueue_to(queue_from_class(klass), klass, *args)
end

or if you are using enqueue_to,

• queue -> queue name as string
• klass -> class
• *args -> arguments

# https://github.com/resque/resque/blob/master/lib/resque.rb#L415
def enqueue_to(queue, klass, *args)

So, in your case,

# using enqueue 
Resque.enqueue(CreateSiteMap, 0, "abc", 1071)

# using enqueue_to
Resque.enqueue_to('high', CreateSiteMap, 0, "abc", 1071)

NOTE: the queue in enqueue_to is a string
