Rails 4 newbe : Routing Error -

Question

I am very new to rails. No idea how to fix it. I cannot even start a simple rails app!

Environment:
    Windows 7
    Ruby 2.1.0
    Rails 4.2.3

First: I ran generate command

D:\\railprojects\\blog>rails generate controller Pages index

routes.rb

    Rails.application.routes.draw do
  get 'pages/index'

end

pages_controller.rb

class PagesController < ApplicationController
  def index
  end
end

index.html.erb

<h1>Pages#index</h1>
<p>Find me in app/views/pages/index.html.erb</p>

I am getting following error.

http://127.0.0.1:3000/pages

Answer 1

try

localhost:3000/pages/index

or if you want to go on index page with this localhost:3000/pages change routes

resources :pages

Answer 2

You should point

http://localhost:3000/pages/index

in your browser to reach proper action.

This is because of your route configuration:

get 'pages/index'

If you would like to be able to point /pages , you have to reconfigure it to look like:

get 'pages', to: 'pages#index'

You can find more about Rails routing here ;

Good luck!

UPDATE

The whole content of config/routes.rb should look like:

Rails.application.routes.draw do
  get 'pages', to: 'pages#index'
end

Answer 3

First of all, dont use Windows to developing in Rails... YOu will have a lot of headaches. Believe in me.

If you dont want to install Linux (like ubuntu), you can use vagrant ( https://www.vagrantup.com/ ).

About your error, you defined pages/index route, but you are trying to visit pages route.

What you can is, is define the pages route, like:

get 'pages', to: 'pages#index'

with that, you can visit you page in this way: http://localhost:3000/pages which will send you to PagesController and index action.

About another error: ExecJS::ProgramError in Pages#index Showing ...

• You need a javascript runtime, like: NodeJS - https://nodejs.org/ installed.
