NoMethodError in Posts#show---Undefined method 'title'(Blog Tutorial)

Question

getting the undefined method 'title' error in my show view. This has been posted and resolved several in other posts but for seemingly other problems than mine.

I have also double checked that I can read from the database through the rails console and everything looks fine.

Loading development environment (Rails 4.2.3)
irb(main):001:0>
irb(main):002:0*
irb(main):003:0* post = Post.find(4)
Post Load (1.0ms)  SELECT  "posts".* FROM "posts" WHERE "posts"."id" =   $1 LIMI
T 1  [["id", 4]]
=> #<Post id: 4, title: "Why Title Why", body: "Where is the Body??", category_i
d: nil, author_id: nil, created_at: "2015-08-12 14:49:38", updated_at: "2015-08-
12 14:49:38">
irb(main):004:0> post.title
=> "Why Title Why"
irb(main):005:0>

thanks for any help

Answer 1

You have @posts variable (@posts = Post.all) inside controller that could be accessed from view.

When you are rendering view file (show.html.erb) - you ask view to find variable @post with parameter .title, .created, .body - @posts inside controller and @post in view - different variables.

So, you need change your view show.html.erb

<h1><%= @posts.title %></h1>
<small><%= @posts.created_created %></small>
<p><%= @posts.body %></p>

or variable inside function of Controller:

def index
    @post = Post.all
end

def show
  @post = Post.find(params[:id])
end
