NoMethodError in

Posts#show Hello,

I’m new at Ruby on Rails, I’m using : -Ubuntu 14.04 LTS -Rails 4.1.2 -Ruby 2.1.2p95 -rvm 1.25.27

I’m actually following the rails guides : http://guides.rubyonrails.org/v4.0.6/getting_started.html#getting-up-and-running Everything was going well until the point : 5.7 Showing points. I have checked my files several times and I can’t figure out where is my mistake, I can submit a post and then there is no display I get the error :

Showing /home/jeremy/projet/blog/app/views/posts/show.html.erb where line #3 raised:

undefined method `title' for nil:NilClass

Extracted source (around line #3):

<p>

<strong>Title:</strong>

<%= @post.title %>

</p>

Following you'll find my files :
-config/routes.rb
Rails.application.routes.draw do
  get 'welcome/index'

  # The priority is based upon order of creation: first created -> highest priority.
  # See how all your routes lay out with "rake routes".
  resources :posts
  # You can have the root of your site routed with "root"
  root 'welcome#index'

  # Example of regular route:
  #   get 'products/:id' => 'catalog#view'

  # Example of named route that can be invoked with purchase_url(id: product.id)
  #   get 'products/:id/purchase' => 'catalog#purchase', as: :purchase

  # Example resource route (maps HTTP verbs to controller actions automatically):
  #   resources :products

  # Example resource route with options:
  #   resources :products do
  #     member do
  #       get 'short'
  #       post 'toggle'
  #     end

Hey Jeremy,

Your Code is Good. Please add below code in to your show.html.erb

<% if @post.present? %>

****

Title:

<%= @post.title %>

Text:

<%= @post.text %>

**<% else %>**

There is no posts to show

<% end %>

Hi,

Move you show method above the private, just like your new and create method.
