Ruby 未初始化的常量Model1:：Model2:：Model3

我正在获取未初始化的常量项目：：论坛：：主题

app/controllers/home_controller.rb:46:in `discussions'

我有下面的代码，我正在从

rails 2.3.x

转换到

rails 3.2.11

，我认为

路由设置有问题

知道我该怎么修吗

型号

class Project < ActiveRecord::Base
      # Relations under project model
      has_many :features, :dependent => :destroy
      has_many :forums, :class_name=>'Forum::Forum'
      has_many :topics, :class_name=>'Forum::Topic', :through=>:forums
class Forum::Forum < Feature
  # Relations under forum model
  has_many :topics, :class_name => 'Forum::Topic', :dependent => :destroy

class Feature < ActiveRecord::Base
  # Relations under feature model
  belongs_to :project

class Forum::Topic < ActiveRecord::Base
   # Relations under topic model
   belongs_to :forum, :foreign_key => :forum_id, :class_name => 'Forum::Forum', :include => :project

uninitialized constant Project::Forum::Topic
app/controllers/home_controller.rb:46:in `discussions'

routes.rb

def discussions
  @project ||= Project.find_by_name 'help'
  @forums = @project.forums
  @topics = @project.topics.recent # HERE I AM GETTING ERRORS
end

scope :home, :controller => "home", :activity => 'read' do
 get :discussions, :path => '/forums', :service_type => 'public'
 get :forums, :action => "discussions"
end

错误

class Project < ActiveRecord::Base
      # Relations under project model
      has_many :features, :dependent => :destroy
      has_many :forums, :class_name=>'Forum::Forum'
      has_many :topics, :class_name=>'Forum::Topic', :through=>:forums
class Forum::Forum < Feature
  # Relations under forum model
  has_many :topics, :class_name => 'Forum::Topic', :dependent => :destroy

class Feature < ActiveRecord::Base
  # Relations under feature model
  belongs_to :project

class Forum::Topic < ActiveRecord::Base
   # Relations under topic model
   belongs_to :forum, :foreign_key => :forum_id, :class_name => 'Forum::Forum', :include => :project

uninitialized constant Project::Forum::Topic
app/controllers/home_controller.rb:46:in `discussions'

如果您自动加载该类（也就是说，您不需要
它的源文件），那么原因可能是Ruby
自动加载
的错误，无法自动加载嵌套的常量3次或更多次

目前我在互联网上找不到我的信息来源；但是，我记得它应该用Ruby 2.0来解决，所以你可以修复它，从
自动加载中删除你需要的文件，在你需要的地方添加
需要的“project/forum/topic”，或者升级到Ruby 2.0

在项目模型类中，按以下方式更改

旧：
有很多：主题，：class\u name=>'Forum:：Topic'，：through=>:forums

新：
有很多：主题，：class\u name=>'：：Forum:：Topic'，：through=>:forums

它应该可以工作
您可以包括这些类在哪些文件中定义吗？我注意到您还缺少类名称之前的
类调用。代码真的是这样吗？@RyanBigg，更新了我的问题我没听清楚，我使用的是Rails 3.2。xRails不属于我的问题，它是Ruby问题；您如何调用定义
项目
、
论坛
和
主题
的文件？它们所在的文件夹结构是什么？
