NoMethodError on section 5.7 of Rails Guide - ruby-on-rails

Question

I'm following the Getting Started tutorial for Rails 4.0.0 located here:
http://guides.rubyonrails.org/getting_started.html
I'm at the point in section 5.7 where I'm supposed to be getting the ActiveModel::ForbiddenAttributes error. Instead, I get this error:
NoMethodError in Posts#show
Showing C:/Rails/blog/app/views/posts/show.html.erb where line #8 raised:
undefined method `text' for nil:NilClass
Extracted source (around line #8):
5
6 <p>
7 <strong>Text:</strong>
8 <%= #post.text %>
9 </p>
Despite this, I believe the posts are being created, since the ids are being incremented each time I submit the form. I am brand new to Rails, and have attempted to exactly follow the instructions.
I'm running Windows 7 x64, with Ruby 1.9.3 and Rails 4.0.0.
Here are some relevant files; please let me know if any other are required.
posts_controller.rb:
class PostsController < ApplicationController
def new
end
def create
#post = Post.new(post_params)
#post.save
redirect_to #post
end
private
def post_params
params.require(:post).permit(:title, :text)
end
def show
#post = Post.find(params[:id])
end
end
show.html.erb:
<p>
<strong>Title:</strong>
<%= #post.title %>
</p>
<p>
<strong>Text:</strong>
<%= #post.text %>
</p>
new.html.erb
<h1>New Post</h1>
<%= form_for :post, url: posts_path do |f| %>
<p>
<%= f.label :title %><br>
<%= f.text_field :title %>
</p>
<p>
<%= f.label :text %><br>
<%= f.text_area :text %>
</p>
<p>
<%= f.submit %>
</p>
<% end %>

Answer 1

Just write down show method after create method, as your show method is below the keyword private it is taking private as a Access Modifier and hence can't access directly through browser
class PostsController < ApplicationController
def new
end
def create
#post = Post.new(post_params)
#post.save
redirect_to #post
end
def show
#post = Post.find(params[:id])
end
private
def post_params
params.require(:post).permit(:title, :text)
end
end

I was having the same problem with the tutorial (which at this date (11/18/14) uses 'articles' instead of 'posts'), and found the solution to be the placement of the following "def" block in articles_controller.rb:
def show
#article = Article.find(params[:id])
end
Here's what it looks like for me:
class ArticlesController < ApplicationController
def new
end
def create
#article = Article.new(article_params)
#article.save
redirect_to #article
end
def show
#article = Article.find(params[:id])
end
private
def article_params
params.require(:article).permit(:title, :text)
end
end
