Small model to get list of repos and create links

github.rb

class Github
  def initialize(username)
    @username = username
  end

  def get_repos
    base_url = "http://github.com/api/v2/json/repos/show/"
    url = "#{base_url}#{@username}"
    resp = Net::HTTP.get_response(URI.parse(url))
    data = resp.body

    result = JSON.parse(data)

    if result.has_key? 'Error'
      raise "web server error"
    end

    return result
  end

  def display
    repos = "<ul>"

    data = get_repos["repositories"]
    
    data.each do |repo|
      link = "<li><a href='#{repo["url"].to_s}'>#{repo["name"]}</a></li>"
      
      repos << link
    end

    repos << "</ul>"

    return repos
  end
end
