ActiveRecord::RecordNotFound

Question

My first project on ruby on rails. I get this error

My print.html.erb is a static page.It has a link <a href="posts/index">Show</a>

And the print page is the index page in my case i.e localhost:3000 opens the print page.

This is my index.html.erb page(this is the linked page)

<h1>Listing posts</h1>

<table>
  <tr>
    <th>Title</th>
    <th>Text</th>
  </tr>

  <% @posts.each do |post| %>
    <tr>
      <td><%= post.title %></td>
      <td><%= post.text %></td>
    </tr>
  <% end %>
</table>

This is my controller

class PostsController < ApplicationController
def index
  @posts = Post.all
end

 def new
  end

def create
  @post = Post.new(post_params)
  @post.save
  redirect_to @post
end

  def post_params
    params.require(:post).permit(:title, :text)
  end

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

def print
end

end

This is my routes file

Watermark::Application.routes.draw do
resources :posts
  root "posts#print"

  post 'posts/index' => 'posts#index'
  post ':controller(/:action(/:id(.:format)))'
  get ':controller(/:action(/:id(.:format)))'
end

I guess the problem is in the routes file.

Answer 1

Your routes contain some bogus additions. You shouldn't have added

post 'posts/index' => 'posts#index'

That's only going to conflict with existing routes. You should remove it.

resources :posts is all you need to generate the seven default RESTful routes in Rails, including index, which should simply by at /posts, not /posts/index.

You should also remove the two catch-all routes, they're not useful anymore. It seems likely that you're working from a pretty dated tutorial.
