title: Sidekiq-scheduler passing arguments
body: <p>I have a use case where I need to do do some task 1 day after a product is uploaded.
  My worker class is written below:</p>
  
  <pre><code>require 'sidekiq-scheduler'
  class ProductWorker &lt; ActiveRecord::Base
     include Sidekiq::Worker
     def self.day_after_upload(product_id)
        #do something
     end 
     def self.week_after_upload(product_id)
        #do something
     end 
  end
  </code></pre>
  
  <p>My product controller is below</p>
  
  <pre><code>class ProductsController &lt; ApplicationController
     def create
        product=Product.new(product_params)
        if product.save! 
            Sidekiq.set_schedule('day_after_upload', { 'at' =&gt; [prduct.created_at+1.day], 'class' =&gt; 'ProductWorker' })
            Sidekiq.set_schedule('week_after_upload', { 'at' =&gt; [product.created_at+1.week], 'class' =&gt; 'ProductWorker' })
        end
      end    
  end
  </code></pre>
  
  <p>I am having trouble passing the 'product_id' parameter to the worker. I couldn't find how to pass custom parameter on sidekiq-scheduler github page . How do I pass custom parameters and do I need to make some other changes for this to work? Any help is appreciated.</p>
