Rails namespace controllers

Question

I've created a new page and for some reason i cannot find it.

I've used rails generate controller dashboard index Which worked fine. I then went into the routes file and added this

namespace :dashboard do
  get 'dashboard' => 'dashboard#index'
end

My file tree is like this views --> dashboard --> index.html.erb

My helper is just this

module DashboardHelper
end

my controller has just got the def index end inside

Any ideas what im doing wrong?

if i go to /dashboard i get this error No route matches [GET] "/dashboard"

Cheers

if get 'dashboard' => 'dashboard#index' outside namespace in your routes it will work, else your controller should have Dashboard::DashboardController < ApplicationController and views folder structure should be /dashboard/dashboard/index.html.erb — Arun

If you are use a namespace option in routes.rb, you should wrap your controller class in namespace also you should put it in own folders.

To make it faster delete your current controller:

rails destroy controller dashboard

And generate new:

rails generate controller dashboard/dashboard index

Rails generate for you controller, inserts the right routes and add views.

$> rails generate controller dashboard/dashboard index
#> create  app/controllers/dashboard/dashboard_controller.rb
#>  route  namespace :dashboard do
#>    get 'dashboard/index'
#>  end
#> invoke  erb
#> create    app/views/dashboard/dashboard
#> create    app/views/dashboard/dashboard/index.html.erb

Your dashboard controller should be

class Dashboard::DashboardController < ApplicationController
   def index
   end
end

Your view folder structure should be

views -> dashboard -> dashboard -> index.html.erb
