我已将 Pundit 与 Devise 一起设置为对我的应用程序进行授权。在我的一个控制器中，我有before_action :authorize.

然后我有以下测试：

describe SomeController do
  before(:each) do
    login_user(FactoryGirl.create(:user, :user_type => :admin))
  end

  describe "GET index" do
    it "it retrieves the index" do
      something = FactoryGirl.create(:Something)
      get :index
      assigns(:something).should eq([something])
    end
  end
end

我收到错误：

wrong number of arguments (0 for 1)

登录助手相当简单：

module ControllerMacros
  def login_user(user)
    if user.nil?
      user = FactoryGirl.create(:user)
    end

    @request.env["devise.mapping"] = Devise.mappings[:user]
    sign_in user
  end
end

更新： 堆栈跟踪：

Failure/Error: get :index
     ArgumentError:
       wrong number of arguments (0 for 1..2)

Pundit 的authorize方法不打算被称为before_action. before_action调用不带参数的方法，并authorize采用模型对象和可选的权限名称。这就是你得到错误的原因。

您没有显示足够的相关代码让我看到您下一步应该做什么，但我建议让 Pundit 在您的控制器操作中工作，然后再将其拉出回调。

这里有一个正确使用的例子authorize：https ://github.com/elabs/pundit

你可以在你的控制器中定义一个私有的辅助方法（或者application_controller如果你将在所有的控制器中使用它），它调用authorize current_user，然后调用私有方法before_action。像这样：

    private
    def perform_authorization
      authorize current_user
    end

然后将其称为before_action：

    before_action :perform_authorization
