I was working on this rails tutorial: "http://guides.rubyon...ng_started.html" and than I got to the part that you are supposed to show the title and data for an individual post (5.7) and got an error when it was supposed to show the data, so I put @post.inspect into /app/views/posts/show.html.erb and I got nil, and same with the index page where it lists all of the posts, but I checked and the data is in the database correctly.(in case this helps, on part 4.3 where you're supposed to uncomment # root to: "welcome#index", the file said #root "welcome#index" instead, even though I'm using rails 4.0 and ruby 2.0) Here's my controller file: class PostsController < ApplicationController def new end def create @post = Post.new(post_params.permit(:title, :text)) @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 def index @posts = Post.all end end here's the error: NoMethodError in Posts#show Showing /home/hiram/rails/meme/app/views/posts/show.html.erb where line #3 raised: undefined method `title' for nil:NilClass Extracted source (around line #3): 1 <p> 2 <strong>Title:</strong> 3 <%= @post.title %> 4 </p> 5 6 <p> Rails.root: /home/hiram/rails/meme

Once you declare private, everything defined after that will be considered private unless you change the declaration. The way you have this coded, the methods show and index will now be private and not available to the view.
