活动记录关系-未初始化的常量用户

Question

下面的代码适用于Rails-2应用程序，但它不适用于Rails-3升级：

In user.rb模型：

has_many :auction_lots, :class_name => "Auction::Lot", :order => "position"

In lot.rb模型：

class Auction::Lot < ActiveRecord::Base
   include ActionController::UrlWriter
   belongs_to :user
   scope :unplanned, :conditions => "status < #{STATUS[:in_stock]}"
end

ActionView::Template::Error (未初始化常量用户：：AuctionLot)：

150:     <% unless current_user.auction_lots.unplanned.empty? %>

activerecord (3.2.13) lib/active_record/inheritance.rb:111:in `compute_type'
activerecord (3.2.13) lib/active_record/reflection.rb:172:in `klass'
activerecord (3.2.13) lib/active_record/associations/association.rb:117:in `klass'
activerecord (3.2.13) lib/active_record/associations/collection_proxy.rb:86:in `method_missing'

请解释一下。rails-2和rails-3之间有什么问题？

Answer 1

Urlwriter不包括Rails-3。

它包含“包含Rails.application.routes.url_helpers”的正确方式。

对我来说很管用。
