helper: Getting the full URL

There’s nothing built in Rails that gives you the full URL. I made a helper, that gives this to you. It doesn’t display properly here.

  def get_full_url(base_url)
    return base_url + request.path + get_params_as_url_friendly
  end
  
  def get_params_as_url_friendly
    count = 0
    param_size = request.query_parameters.size
    parameters = ""
    
    for param in request.query_parameters
      parameter = "#{param[0]}=#{param[1]}"
      
      if count == 0
        parameter = "?#{parameter}"
      else
        parameter = "&#{parameter}"
      end
      
      count += 1
      parameters += parameter
    end
    
    return parameters
  end

Helper: get_url(url)

Answer to making our relative URLs to absolute URLs through the application helper:

def get_url(url)
  return "http://localhost:3000" + url
end

If URL were /model/file/1/a.jpg, then you'd get http://localhost:3000/model/file/1/a.jpg in return. When moving to a new webserver, we just need to edit the helper and change the base URL.
