我错过了什么？我正在尝试使用Active资源的休息服务,我有以下内容:

class User < ActiveResource::Base
  self.site = "http://localhost:3000/"
  self.element_name = "users"
  self.format = :json
end

user = User.new(
        :name => "Test",
        :email => "test.user@domain.com")

p user 
if user.save
  puts "success: #{user.uuid}"
else
  puts "error: #{user.errors.full_messages.to_sentence}"
end

并为用户输出以下内容:

#<User:0x1011a2d20 @prefix_options={}, @attributes={"name"=>"Test", "email"=>"test.user@domain.com"}>

而这个错误:
