ruby-on-rails-3 - "Module is not missing constant Model"- Rails 3 错误

Question

我在我的应用程序中命名了我的模型和 Controller 。

当我尝试访问 admin/stories.html (NameSpace::Admin::StoriesController)

我不断收到错误消息“NameSpace 没有缺少常量 Story!”

这是我的 Controller 的副本以供引用:

class NameSpace::Admin::StoriesController < NameSpace::ApplicationController

  layout "admin"
  before_filter :admin_login_required

  cache_sweeper NameSpace::StorySweeper, :only => [:update,:destroy]

  # expose is provided by the DecentExposure Gem
  expose(:stories) { current_place.stories.where(:state => %w{ submitted published }).order("created_at DESC").page(params[:page]).per(25) }
  expose(:story)

  def create
    if params[:success] == "1"
      Story.find_or_create_by_media_id(params[:media_id])      
      redirect_to admin_stories_url, :notice => "Successfully created story! It should appear here in a few minuntes once it's been processed."
    else
      flash.now[:error] = "There was an error when creating your story!<br>If this happens again, please contact support@#{APP_CONFIG[:domain]}".html_safe
      render :new
    end
  end

  def index
  end

  def show
  end

  def new
  end

  def edit
  end

  def update
    if story.update_attributes(params[:story])
      redirect_to admin_stories_url, :notice => "Successfully updated story."
    else
      render :action => 'edit'
    end
  end

  def destroy
    story.remove!
    redirect_to admin_stories_url, :notice => "Story successfully destroyed!"
  end

end

我正在使用带有 REE 的 Rails 3.1.0.beta1

Answer 1

使用 module而不是类名的冒号表示命名空间在 Rails 3.0.15 中为我解决了这个问题

例如

module Foo
  class Bar
  ...
  end
end

对比

class Foo::Bar
end
