Active resource error expecting hash

Hello,
I want to call a REST API with active resource, described here:
http://www.redmine.org/projects/redmine/wiki/Rest_api_with_ruby
this is my code:
require ‘active_resource’
class Issue < ActiveResource::Base
ActiveResource::Base.include_root_in_json = true
self.site = ‘http://demo.redmine.org/
end

Retrieving issues

issue = Issue.find(:all)
and getting this error:
/activeresource-4.0.0/lib/active_resource/base.rb:1327:in load': expected an attributes Hash, got ["issues", [{"id"=>91663, "project"=>{"id"=>77006, "name"=>"proj1"},.... The link mentions: *You may need to set include_root_in_json = true` in your ActiveResource class*

But I don’t understand where and how.
Greatly appreciate your help.

Cheers,
Peter

Your `find` is expecting a singular element name back: 'issue' rather
than 'issues'.

Take a look at this:
http://www.rubydoc.info/gems/activeresource/4.0.0/ActiveResource/Collection

And do something like this:

** issue.rb **
require 'active_resource'

class Issue < ActiveResource::Base
  self.site = ‘http://demo.redmine.org/
  self.collection_parser = IssueCollection
end

** issue_collection.rb **
class IssueCollection < ActiveResource::Collection
  def initialize(parsed = {})
    @elements = parsed['issues']
  end
end

HTH,
