It seems like some people here had this problem but I couldn't find any solution in another topic.
I am doing Chapter 3 of the Ruby on Rails-Tutorial, working on the static pages. When I want to open them on the localhost it gives me a "Routing Error" in the Browser.
My Ruby is currently on version 1.9.3. My Rails is currently on version 3.2.
I have tried:
- restarting the server
- saving all the files again
- checking any issues in the static_pages_controller.rb
- checking any issues in the routes.rb
- checking any issues in the static_oages_spec.rb
Also there are no bugs in the HTML code of the single static page. And I can't find any more help in the tutorial, neither in other questions here on StackOverflow.
Edit:
This is the actual error message from the browser:
Routing Error
No route matches [GET] "/static_pages/home" Try running rake routes for more information on available routes.
if I go to http://localhost:3000/static_pages/home, to one of three static pages I have.
This is routes.rb:
SampleApp::Application.routes.draw do
get "static_pages/home"
get "static_pages/help"
get "static_pages/about"
end
Also, I tried "rake routes" in the terminal, too. This is the result:
home_static_pages GET /static_pages/home(.:format) static_pages#home
help_static_pages GET /static_pages/help(.:format) static_pages#help
about_static_pages GET /static_pages/about(.:format) static_pages#about
static_pages POST /static_pages(.:format) static_pages#create
new_static_pages GET /static_pages/new(.:format) static_pages#new
edit_static_pages GET /static_pages/edit(.:format) static_pages#edit
GET /static_pages(.:format) static_pages#show
PUT /static_pages(.:format) static_pages#update
DELETE /static_pages(.:format) static_pages#destroy
And this is the error message the server is giving me:

Try this :
match "/static_pages/home" => "static_pages#home", :via => :get
match "/static_pages/help" => "static_pages#help", :via => :get
match "/static_pages/about" => "static_pages#about", :via => :get
Add into routes , restart the server and refresh browser .
If you are using Spork you must re-run Spork so your tests will consider the changes in config files like routes.rb, that are pre-loaded with Spork, so are not automatically updated.
- Stop Spork (Ctrl + C)
- Run Spork again (bundle exec spork)
Source: this is the source of this information "after changing a file included in the prefork loading (such as routes.rb), you will have to restart the Spork server to load the new Rails environment. If your tests are failing when you think they should be passing, quit the Spork server with Control-C and restart it
your routes.rb file has problems, use either RESTful style:
resource :static_pages do
collection do
get :home
get :help
get :about
end
end
or the non RESTful style:
match "static_pages/home", :controller => "static_pages", :action => "home"
match "static_pages/help", :controller => "static_pages", :action => "help"
match "static_pages/about", :controller => "static_pages", :action => "about"
for more details please refer to official guide: http://guides.rubyonrails.org/routing.html
I had a few problems working through the Rails Tutorial, and it helped to be able to consult the author's GitHub repo: https://github.com/railstutorial
Find the file you're working on and compare it line by line. Or just cut and paste the full file and see if it will run, then track down your error.
If you check the routes.rb in config you'll probably find that the there is a 'e' missing from /home. Add that and you are golden. Or green. Or whatever :)
check your http:// address, specifically if you are on localhost:3000/path or localhost:3000/path1/path2, etc
Once you change the format of your mapping from get to match you will not need static_pages anymore, just go straight to localhost:3000/pagename e.g localhost:3000/about
From Ruby 2 to Ruby 3 there are some differences, but still the documentation for 3 is not easy to be found. There should be a tutorial only for that: practical differences between rails 2 and 3. The guide provided by downloading Ruby on rails is "The book of ruby" but it's not good anymore. It should at least contain an advice at the beginning of chapter 19.
In
config/routes.rb
uncomment
root :to => 'welcome#index'
