I am working with Rails for the first time and got the Apache-Mongrel integration working and have the index.html page showing up when I open localhost in the browser.
I created the controller (ruby script/generate controller Welcome index) and renamed the index.html file.
However, when I try to map to a controller in routes.rb (map.root :controller => "welcome") things break. I can start the ruby server (ruby script/server) and browse to localhost:3000 works.
You are making a reference to a controller named "Welcome". Renaming the Html file in the public folder is useless. You should create a controller called "Welcome " and then add a method, such as "index".
And then in the routes.rb file you should add: "map.root: controller => 'welcome',: action => 'index'"
Delete index.html file too, it will prevent your routes from working.

I am stuck and unable to proceed on my Ruby on Rails tutorial.
I am doing a Ruby on Rails tutorial using a mac.
I have created a new Ruby on Rails project in Users/username/sites/simple_cms
I am using Webrick server
I started the server using rails s command and as expected, when navigating to the localhost:3000 the public index page was displayed.
I then added a controller and view using the following command in the route directory:
rails generate controller demo index
The controller and view were successfully created:
My routes file:
SimpleCms::Application.routes.draw do
get "demo/index"
My demo_controller File:
class DemoController < ApplicationController
def index
end
end
My View file is now located in views/demo/index.html.erb:
<h1>Demo#index</h1>
<p>hello world</p>
I then started Webrick again and entered:
http://localhost:3000/demo/index
but a blank page is displayed.
add root to 'demo#index' to routes file http://guides.rubyonrails.org/routing.html#using-root
Try to change your route as follows
get "index" => "demo#index"
then you can access the site with localhost:3000/index
But if this is your root path you can also do
root "demo#index"
to access the site with localhost:3000
In this case demo refers to your controller and index to your action in the controller.
I'm very new to RoR and I'm trying to get a very basic site going. I have my home page working okay, but when I try to add a new page, I keep getting "No route matches" in the log. Here is the output from rake routes:
Prefix Verb URI Pattern Controller#Action
inventing_index GET /inventing/index(.:format) inventing#index
ideas_index GET /ideas/index(.:format) ideas#index
root GET / ideas#index
However, when I go to mysite.com/inventing or mysite.com/inventing/index I get the no route matches error. mysite.com/ shows the app/views/ideas.erb as hoped. All I did was rails generate controller inventing index. Is there something else I have to do to activate the route?
I'm running ruby 2.0.0p247 and rails 4.0.0 with passenger/apache on centos 6. I installed all the ruby/rails/passenger stuff, so its possible something isn't setup properly.
Thanks
EDIT: Here is my routes.db file:
Rortest::Application.routes.draw do
get "inventing/index"
get "ideas/index"
root to: 'ideas#index'
end
tldr: Your problem is probably the route. Change get 'inventing/index' to get 'inventing/index'=> 'inventings#index' to correctly point the route to your controller action.
There are four things you need to do when adding a new page/route. I usually do them in this order for static pages:
1) Create a controller with the appropriate action for each page
You already did this with rails generate controller inventing index, but make sure that:
In your app/controllers folder, you do indeed have a file called inventings_controller.rb
In inventings_controller.rb, you have at least this:
class InventingsController < ApplicationController
def index
end
end
2) Create a view for each controller action
Make sure that:
In your app/views/inventings folder, you have a file called index.html.erb
Puts some simple HTML in that file, like <h1>Testing123</h1>, just so you can see if it's working.
3) Add a route for each controller action
It looks like this may be the problem. In your routes.rb file, you'll need this:
get 'inventing/index' => 'inventings#index'
Your root to works because it's actually pointing directly to your controller action, but rails isn't smart enough to guess that inventing/index should go to the index action in your inventing**s** controller.
4) As others have suggested, restart your rails app
You can do this with ctrl+c at the command line, then rails s again to start it back up.
I'm new in ruby on rails and I have a problem. When I starе server " rails server and going to the page
www.localhost:3000
in my browser everything works fine with ROR default page, but.... after making controller rails generate controller demo index
and going to the page
www.localhost:3000/demo/index , localhost:3000/demo - the same
- there is nothing, seems like page doesn't exist, only a blank page. I tried to change index.html.erb code
<h1>Hello World</h1>
- no change. I want to practice with ROR, but can't because of that bug.

You need to have a view corresponding to your action.
If your controller is called Demo and your action is index it should be
# app/controllers/demo_controller.rb
class DemoController < ApplicationController
def index
end
end
and the view file should be at app/views/demo/index.html.erb.
The index action is the base action of the controller. Try just:
http://localhost:3000/demo
to access the index.
By default routes /demo/index is the show action with the id of index.
make sure
views/layout/application.html.erb has yield and index.html.erb have some text
check your routes.rb
root :to => 'demo#index'
Go to http://localhost:3000/
Uncomment this line from your config/routes.rb file
match ':controller(/:action(/:id))(.:format)'
Remove index.html file from public/index.html
First of all delete or rename the index.html file from public folder.
Then set root :to => 'demo#index' at route file.
Then restart the server by using this command. rails s by default your server will run at port 3000.
Now simply type http://localhost:3000/ or http://localhost:3000/demo/index
Have you deleted
app_root
--public
----index.html
yet?
Rails will look in the public folder first for a matching file before it will goto build one from your views.
As indicated by João there, you will also need a view for that. Additionally, delete public/index.html and finally add a route for your controller.
If you had created a scaffold Rails start guide you would already have the route there for you.
I have an application where they have used index.rhtml in the main folder as start up page.
So how can I do this on my own using Ruby on rails i.e., How to create rails application with rhtml page as start up file.
Please post links if any for reference.
Thanks,
Kumar Raja Donthamsetti.
Delete public.html
Add 'map.root :controller => "foo"' to routes.rb
and then of course create the controller foo with the action index.
I am new to Ruby on rails and working in a new test application. Consider my application url is : www.test.com
I would like to place a page by creating controller and respective views, the page should look like the below
www.test.com/articles/book-test-page
I created a controller "article" (defined the action as
def book_test_page
...
...
end
and folder under view as view/articles/book-test-page.
What routing information should i add in the routes.rb file to make this url bring up the specified url work? Any suggestion would be helpful..
Thanks,
Balan
get 'articles/book-test-page', :to => 'articles#book_test_page'
