Routing in ruby for controllers

Question

I'm trying to build a simple rails application however I get a routing error. Here is the controller:

class PostsController < ActionController::Base

  def index

    @var = "Rails is amazing"

  end



end

Here is the routing:

get "/posts", to: "posts#index"

And the routing error is as following:

uninitialized constant PostsController

The url im accessing is this one:

http://localhost:3000/posts#

I understand that controllers should be pluralised in both the routing and in the name of the file. I am sorry for such a novice question

I believe, you have posts_controller.rb file in the controllers folder.In the posts_controller.rb file add the following syntax

class PostsController < ApplicationController

end

In your routes file, try adding

resources :routes

In the terminal if you will type CONTROLLER=posts rake routes, you ll get the following output

Prefix Verb   URI Pattern               Controller#Action
    posts GET    /posts(.:format)          posts#index
          POST   /posts(.:format)          posts#create
 new_post GET    /posts/new(.:format)      posts#new
edit_post GET    /posts/:id/edit(.:format) posts#edit
     post GET    /posts/:id(.:format)      posts#show
          PATCH  /posts/:id(.:format)      posts#update
          PUT    /posts/:id(.:format)      posts#update
          DELETE /posts/:id(.:format)      posts#destroy

Ah. So the file name must be posts_controller. I have given it the name of PostsController. That solved it. Thanks

one more quick question. It looks that when i do %= @var % The variable does not get printed into the view.

in your index.html.erb, you need to add <%= @var%>
