Answer 2

i already solved mine,

you dont need to put http://127.0.0.1:3000/index

just this http://127.0.0.1:3000/ since you tell rails to make you index as root.

but you will have get a problem regarding javascript, to sovle you need to edit your application.js

edit this line //= require_tree . to = require_tree .

hope this will help

Answer 3

Try below code:

routes.rb

Rails.application.routes.draw do
  get '/handm/index' => 'handm#index'
  root :to => "handm#index"
end

handm_controller.rb

class HandmController < ApplicationController 
  def index 
    ...
  end 
end

views/handm/index.html.erb

<h1>In index page</h1>

Start your server by command:

rails server

and hit url:

localhost:3000

or

localhost:3000/handm/index

Answer 4

The error means that the specified route or path doesn't exist. So, the solution is to change it to a valid path. We can only guess at the paths supported by your Rails app, but /handm#index is plausible:

Rails.application.routes.draw do
  get '/handm/index' => 'handm#index'
  root :to => "handm#index"
end
