Description

in this file at :

xml.issues :type => 'array' , :count => @issue_count do

The ":count" parameter will cause an error calling issues from activeresource : 

can't typecast "1" 
 ["/var/lib/gems/1.8/gems/activesupport-2.3.5/lib/active_support/core_ext/hash/conversions.rb:182:in `typecast_xml_value'", "/var/lib/gems/1.8/gems/activesupport-2.3.5/lib/active_support/core_ext/hash/conversions.rb:208:in `typecast_xml_value'", "/var/lib/gems/1.8/gems/activesupport-2.3.5/lib/active_support/core_ext/hash/conversions.rb:199:in `inject'",

If you delete this parameter, all is working fine.

REST API bug?

I tried to run the script http://www.redmine.org/wiki/redmine/Rest_api_with_ruby. Displays an error message: /home/artem/.gem/ruby/1.8/gems/activesupport-2.3.5/lib/active_support/core_ext/hash/conversions.rb:182:in `typecast_xml_value': can't typecast "2" (RuntimeError)

I deleted :count => @issue_count in app/views/issues/index.xml.builder and all earned.

I wrote a script rest.rb:

 1require 'rubygems'
 2require 'active_resource'
 3
 4class Issue < ActiveResource::Base
 5   self.site = 'http://www.redmine.org/'   
 6end
 7
 8issues = Issue.find(:all)
 9puts issues.first.subject

$ ruby rest.rb
/home/artem/.gem/ruby/1.8/gems/activesupport-2.3.5/lib/active_support/core_ext/hash/conversions.rb:182:in `typecast_xml_value': can't typecast "1794" (RuntimeError)

 3
 4class Project < ActiveResource::Base
 5   self.site = 'http://www.redmine.org/'   
 6end
 7
 8projects = Project.find(:all)
 9puts projects.first.name

$ ruby rest2.rb
Redmine

I've removed the count attribute in issues.xml. It's not ideal because of the pagination won't show all of the issues but it breaks ActiveResource.

Here's the full error for the search:
