Question

I have written the following code snippet to read data from the database :

    require 'rubygems'
    require 'active_resource'

    class Website < ActiveResource::Base
      self.site = "http://localhost:3000"
    end

    websites = Website.find(:all)
    puts websites.inspect

this gives me following output :

prompt:~/Desktop$ ruby active_resource_example.rb
=> nil

My websites table contains the following fields :

    == Schema Information

 Table name: websites

  id          :integer(4)      not null, primary key
  name        :string(255)
  url         :string(255)
  description :text
  active      :boolean(1)      default(TRUE)
  created_at  :datetime
  updated_at  :datetime

There are records present in my websites table, but why it is showing me nil result. This is the simplest code I could write and still not getting the required result.

Can anyone help me with this?

Answer 1

First of all, you should start web server through call rails server command. I think you already prepared this because in the opposite case you received some errors about connection. Later, you must be sure that your routes contains something like this:

resources :websites

and your website controller contains format.json section in respond_to block.
At last you can check logs – after preparing Website.find(:all) call (to the point – you can use Website.all) you should receive following record:

Started GET "/websites.json" for ....
