Question

Error using ActiveResource with Rails 3 and REST API

Answer 1

A:

Simple answer, if you try to session in your views it will access the Rails Session object, you have a naming problem on your hands.

Thats why the Hash error is coming, it tries to access the session Hash.

Try something like

<h1>List Sessions</h1>
<% @sessions.each do |s| %>
  <div><%= s.title %></div>
<% end %>

And by the way, you might change your controller to:

class HomeController < ApplicationController
  def index
    @sessions = Session.all
  end
end

And I would not use a model or class named `Session` in Rails at all, this will lead to a lot of problems, with paths and everything.

I updated the model name to be `TestSession < ActiveResource::Base`, renamed the file to testsession.rb, and added `self.element_name = 'session'` to the definition. I then tried to return a value from it `@ses = TestSession.all` and got this error: `uninitialized constant HomeController::TestSession`

Seems like it's not finding your Model, sure you have no typos in their? Is your models in app/models? Or add a require in your controller, like require 'test_session'.

should the file be renamed to test_session.rb for it to be found?

Steve Wright 2010-10-26 19:07:35

Yep. File should be named test_session.rb

it was the collision of using the variable name "session" in the view - Thanks
