Does anyone know how to fix any/all of these errors? here are my associated files: routes.rb

SampleApp::Application.routes.draw do

  match '/static_pages/home', :to =>'static_pages#home'
  match '/help' => 'static_pages#help',    :via => 'get'
  match '/about' => 'static_pages#about',   :via => 'get'
  match '/contact' => 'static_pages#contact', :via => 'get'

  get "static_pages/home"

  get "static_pages/help"

  get "static_pages/about"

  get "static_pages/contact"

I have updated my Xcode, libiconv, and everything associated. I am currently most of the way through chapter 5 of the ruby on rails tutorial and I for the life of me have no idea what is causing these errors. I have followed the tutorial perfectly so far with the minor exceptions such as changing a colon method into hash rockets and different gem versions, etc.

rake results:

Answer 1

When you create routes using match and get like that, you don't get named routes like help_path by default. Run rake routes to see which routes are configured, and what their named helpers (if any) are. You likely don't have many named routes.

You can use :as to name your routes:

match '/help' => 'static_pages#help', :via => 'get', :as => 'help'

That will get you help_path and help_url . If you define routes using eg resources :help , a lot of that magic is done for you. In the case of your routes to static assets, using :as is the best approach.
