Question

我的routes.rb文件是

 namespace(:api){
  resources :open_conversations do
    resources :open_answers, :only => [:index, :create, :destroy]
 end

}

和OpenConversation和OpenAnswer控制器文件

class OpenConversation < ActiveRecord::Base
  has_many :open_answers, :dependent => :destroy
end


class OpenAnswer < ActiveRecord::Base
  belongs_to :open_conversation
end

我将OpenConversation模型加载到OpenAnswer控制器

class Api::OpenAnswersController < Api::ApplicationController

  before_filter :get_conversation

  def get_conversation
    binding.pry
    @con = OpenConversation.find(params[:open_conversation_id])
    @answers = @con.open_answers
  end
end

============== 这是IRB调试日志

[6] pry（＃）＆gt; OpenConversation

=＆GT;的阿比:: OpenConversation

[7] pry（＃）＆gt; OpenConversation.find（PARAMS [：open_conversation_id]）

NameError：未初始化的常量Api :: OpenAnswersController :: OpenConversation

from（pry）：6：在`get_conversation'

[8] pry（＃）＆gt; OpenConversation

NameError：未初始化的常量Api :: OpenAnswersController :: OpenConversation

from（pry）：7：在`get_conversation'

[9] pry（＃）＆gt; OpenConversation.class

NameError：未初始化的常量Api :: OpenAnswersController :: OpenConversation

from（pry）：8：在`get_conversation'

为什么OpenConversation模型加载喜欢模块？

Answer 1

你可以给控制器文件树结构。可能是ApplicationController错误地继承了。

class Api::OpenAnswersController < ApplicationController

Rails4，加载ActiveRecord模型无法正常工作
