My rake task for clearing Resque queues and stats

resque.rake

namespace :resque do
  desc "Clear pending tasks"
  task :clear => :environment do
    queues = Resque.queues
    queues.each do |queue_name|
      puts "Clearing #{queue_name}..."
      Resque.redis.del "queue:#{queue_name}"
    end
    
    puts "Clearing delayed..." # in case of scheduler - doesn't break if no scheduler module is installed
    Resque.redis.keys("delayed:*").each do |key|
      Resque.redis.del "#{key}"
    end
    Resque.redis.del "delayed_queue_schedule"
    
    puts "Clearing stats..."
    Resque.redis.set "stat:failed", 0 
    Resque.redis.set "stat:processed", 0
  end
end

I found this useful

puts "Clearing zombie workers..."
Resque.workers.each(&:prune_dead_workers)

Thanks!

much appreciated

This is what works now:

Resque.remove_queue("...")

Updated to merge all of the above and adjust for rubocop:
