我正在测试我的 Rails 3.2 应用程序，但在尝试测试我的控制器时遇到了错误。

这是我的控制器

class WidgetsController < ApplicationController
  #skip_before_filter :authenticate, :only => [:new, :create]
  before_filter :authenticate, :except=>[:disabled]

  def index
    @widgets = current_user.widgets.all
    respond_to do |format|
      format.html # index.html.erb
      format.json { render json: @widgets }
    end
  end

  def new
    @widget = Widget.new
  end

  def create
    @widget = Widget.new(params[:widget])
    @widget.user_id = current_user.id
    @widget.score = 0
    @widget.total_score = 0
    @widget.click_number = 0
    @widget.average = 0
    respond_to do |format|
      if @widget.save
        format.html { redirect_to edit_widget_path(@widget), notice: 'Widget was successfully created.' }
        format.json { render json: @widget, status: :created, location: @widget }
      else
        format.html { render action: "new" }
        format.json { render json: @widget.errors, status: :unprocessable_entity }
        raise 'there is an error when creation'
      end
    end
  end

  def show
    @widget = Widget.find_by_uuid(params[:uuid])
  end

  def edit
    @widget = Widget.find_by_uuid(params[:uuid])
  end

  def update
    @widget = Widget.find_by_uuid(params[:uuid])
    respond_to do |format|
      if @widget.update_attributes(params[:widget])
        format.html { redirect_to edit_widget_path(@widget), notice: 'Widget was successfully updated.' }
        format.json { render json: @widget, status: :created, location: @widget }
      else
        format.html { render action: "edit" }
        format.json { render json: @widget.errors, status: :unprocessable_entity }
      end
    end
  end

  def destroy
    @widget = Widget.find_by_uuid(params[:uuid]).destroy
    redirect_to widgets_path
  end

  #generate widget
  def generate
    respond_to do |format|
      format.js {}
    end
  rescue
    #TODO add widget not found page
    render :template => 'application/widget_not_found', :status => :not_found
  end



  protected

  def authenticate
    unless current_user
      redirect_to root_url
    end
  end

end

这是我的控制器规格

require 'spec_helper'

describe WidgetsController do
  login_admin

  describe "User" do
    it "should have a current_user" do
      subject.current_user.should_not be_nil
    end
  end

  def mock_widget(stubs={})
    @mock_widget ||= mock_model(Widget, stubs).as_null_object
  end

  describe "GET index" do
    it "assigns all widgets as @widgets" do
      Widget.stub(:all) { [mock_widget] }
      get :index
      assigns(:widgets).should eq([mock_widget])
    end
  end

end

我只是想看看我可以在索引页面上获取数据。但是我在运行时在命令行上看到了这个错误$rspec spec/controllers/widgets_controller_spec.rb

我做了这个教程http://www.codethinked.com/rails-3-baby-steps-part-4并且我没有遇到任何问题。我应该如何解决它？这个错误是什么意思？

我猜这与在控制器中确定 current_user 返回的小部件集的范围有关。在控制器中，您正在调用all小部件对象（Widget 类的实例）集合上的方法，而在测试中，您正在all对 Widget 类的方法进行存根。您可以通过将控制器方法更改为简单地调用来测试这个理论Widget.all。我知道这不是您想要的，但它会确认这是问题所在。
