Question

应用程序堆栈：Rails3，CanCan，Devise，Shoulda

我有一些嵌套的资源，想用Shoulda测试它们，我得到以下DoubleRenderError：

Error:
test: If anonymous user tries to GET index of fav_blogs should respond with 401.    (BlogItemsControllerTest):
AbstractController::DoubleRenderError: Render and/or redirect were called multiple times  in this action. Please note that you may only call render OR redirect, and at most once per action. Also note that neither redirect nor render terminate execution of the action, so if you want to exit an action after redirecting, you need to do something like "redirect_to(...) and return".

测试将检查未经过身份验证的用户是否能够访问嵌套资源（他不应该）

TestMethod的

context "If anonymous user tries to GET index of fav_blogs" do
  setup do
    get :index, :end_user_id => end_users(:end_user_one).id, :format => "xml"
  end
  should_respond_with 401
  should_not_assign_to :blog_items
end

ControllerMethod：

def index

  if params[:end_user_id] # if it is nested
    authenticate_end_user!
    authorize! :read, @end_user

    @blog_items = @end_user.blog_items
  else
    @PAGE_SIZE = 10
    page = Integer(params[:page]) || 0

    offset = @PAGE_SIZE * page
    @blog_items = BlogItem.limit( offset + @PAGE_SIZE ).offset( offset ).order('updated_at DESC').all
  end

  respond_with(@blog_items)
end

所有经过身份验证的用户的测试都可以正常工作 - 有人可以给我一个提示。非常感谢！本

Answer 1

好吧我已经完成了 - 因为

而出现了问题

authenticate_end_user!
authorize! :read, @end_user

块。如果没有授权，第一行将呈现401失败，但无论如何，第二行将被执行。因此，将身份验证放在before_filter中，将授权放在另一个或您的控制器操作中。本
