Question

I am certainly losing my head/sleep over this.
This is my questions_controller.rb

class QuestionsController < ApplicationController
  # GET /questions
  # GET /questions.json
  def index
    @questions = Question.all

    respond_to do |format|
      format.html # index.html.erb
      format.json { render json: @questions }
    end
  end

This is my applications_controller.rb

class ApplicationController < ActionController::Base
  protect_from_forgery
end

This is my rake routes:

    questions GET    /questions(.:format)          questions#index
              POST   /questions(.:format)          questions#create
 new_question GET    /questions/new(.:format)      questions#new
edit_question GET    /questions/:id/edit(.:format) questions#edit
     question GET    /questions/:id(.:format)      questions#show
              PUT    /questions/:id(.:format)      questions#update
              DELETE /questions/:id(.:format)      questions#destroy
   home_index GET    /home/index(.:format)         home#index

This is my routes.rb

App::Application.routes.draw do
  resources :questions
end

Error on going to http://0.0.0.0:3000/questions

uninitialized constant QuestionsController

What might be the error?

Answer 1

This kind of errors sometimes happen when there is a syntax error in one of files. Restart your dev server and look up for errors in its output.

Especially check line

format.html # index.html.erb

I don’t think it can be written this way.
