我正在尝试让 RSpec 控制器规范通过。它几乎与脚手架生成的规范相同，只是用户首先登录设计。如果我从控制器（检查权限）禁用“load_and_authorize_resource”，一切正常。但是如果我把线放回去，它会失败：

  1) PostsController logged in administrator POST create with valid params assigns a newly created post as @post
     Failure/Error: post :create, :post => {'title' => 'test title'}
       <Post(id: integer, title: string, cached_slug: string, content: text, user_id: integer, created_at: datetime, updated_at: datetime) (class)> received :new with unexpected arguments
         expected: ({"title"=>"test title"})
              got: (no args)
     # ./spec/controllers/posts_controller_spec.rb:52:in `block (5 levels) in <top (required)>'

我曾假设规范没有正确登录用户，但 puts current_user.role.name 确认用户已正确登录，并具有必要的角色。在浏览器中执行实际过程确认它按预期工作。

有人有什么建议吗？我很困惑。下面的控制器：

  def create
    @post = Post.new(params[:post])
    @post.user = current_user
    respond_to do |format|
      if @post.save
        flash[:notice] = "Post successfully created"
        format.html { redirect_to(@post)}
        format.xml  { render :xml => @post, :status => :created, :location => @post }
      else
        format.html { render :action => "new" }
        format.xml  { render :xml => @post.errors, :status => :unprocessable_entity }
      end
    end
  end

...和规格

  describe "with valid params" do
    it "assigns a newly created post as @post" do
      Post.stub(:new).with({'title' => 'test title'}) { mock_post(:save => true) }
      post :create, :post => {'title' => 'test title'}
      assigns(:post).should be(mock_post)
    end

...并支持规范中的内容：

before(:each) do
  @user = Factory(:admin)
  sign_in @user
end

  def mock_post(stubs={})
    @mock_post ||= mock_model(Post, stubs).as_null_object
  end

非常感谢...

尝试将 CanCan 升级到 1.5 版。我之前遇到过这个问题，但我认为升级后它就消失了。
