Unknown action No action responded to 2. Actions: show
I''m trying to create a simple RoR application that shows me the records
inside my table, provided that it is an example I''m working on the
"Head
First Rails" book.
When I try to retrieve the record I get the following message:
"Unknown action
No action responded to 2. Actions: show"
Why am I having that? And, how can I fix this issue?
Provided that:
1- I have inserted one record in the SQLite3 database in the table
"ads".
2- route.rb
ActionController::Routing::Routes.draw do |map|
map.connect ''/ads/id'',
:controller=>''ads'', :action=>''show''
map.connect '':controller/:action/:id''
map.connect '':controller/:action/:id.:format''
end
2- ads_controller.rb
class AdsController < ApplicationController
def show
@ad = Ad.find(params[:id])
end
end
3- show.html.erb
<html>
<head>
<title><%= @ad.name %></title>
</head>
<body>
<p>
<b>Name: </b><%= @ad. name %>
</p>
<p>
<b>Description:</b><%= @ad. description %>
</p>
<p>
<b>Price: </b><%= @ad. price %>
</p>
<p>
<b>Seller Id: </b><%= @ad. seller_id %>
</p>
<p>
<b>Email: </b><%= @ad. email %>
</p>
<p>
<img src="<%= @ad.img_url %>"/>
</p>
</body>
</html>
Thanks.

Re: Unknown action No action responded to 2. Actions: show
The issue was that I forgot to insert the colon before id -> :id map.connect ''/ads/id'', :controller=>''ads'', :action=>''show'' Thanks.

Re: Unknown action No action responded to 2. Actions: show
in routes, delete all, and write ActionController::Routing::Routes.draw do |map| resources :ads end then in console write rake routes u will see all routes in your application than go to guides.rubyonrails.com and start read it _ thanks Ivan Nastyukhin dieinzige-BUHhN+a2lJ4@public.gmane.org On Jun 21, 2010, at 2:41 PM, SWEngineer wrote:> I''m trying to create a simple RoR application that shows me the > records > inside my table, provided that it is an example I''m working on the > "Head > First Rails" book. > > When I try to retrieve the record I get the following message: > > "Unknown action > > No action responded to 2.
