rails LoadError: cannot load such file -- lib/scraper

Question

In my rails app, I have a rake task that scrapes data from another webpage. I want to move the method functionality out of the rake task into a ruby class or module. To do, I have the rake task in lib/tasks, then scraper.rb in lib. In the rake task, I have require 'lib/scraper' but this throws an error.

Here is my rake task:

require "lib/scraper"
namespace :some_namespace do
    desc "A description"
    task :scrape_info => :environment do
        scraper = Scraper.new
        scraper.scrape_info
    end
end

And the ruby scraper class:

require 'mechanize'
class Scraper
    def scrape_info
        mechanize = Mechanize.new

        # Scrape players from fox sports
        url = "someurl"

        # do some other stuff
    end
end

Answer 1

Your code should look as follows.

lib/scraper.rb:

require 'mechanize'

module Scraper
  class Scraper
    def scrape_info
    end
  end
end

lib/tasks/some_namespace.rake:

namespace :some_namespace do
  task some_task :environment do
    include Scraper
  end
end
