title: Dynamically include modules in another module in Rails
body: <p>I want to dynamically include all modules within a certain folder into this other module. My code is as follows:</p>
  
  <pre><code>module Extensions
    module ProductExtension
      def add_included_extensions
        extensions = Pathname.glob("lib/extensions/merchant/*.rb")
          .map(&amp;:basename)
          .collect{|x| 
            x.to_s.gsub(".rb", "")
            .titleize.gsub(" ","")
          }
  
        extensions.each do |merchant|
          include "Extensions::MerchantExtensions::#{merchant}".constantize
        end
      end
      def add_items
        add_included_extensions
        Merchant.all.each do |merchant|
          send("add_#{merchant.name.downcase}_items")
        end
      end
    end
  end
  </code></pre>
  
  <p>However it doesn't seem to be actually including the files because when I call the send method, it says the method it's calling doesn't exist. Any idea what I could be doing wrong?</p>
