NoMethodError on section 5.7 of Rails Guide

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

Answer 1

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

Answer 2

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
