ruby on rails - Why does before_action :authorize fail with 'wrong number of arguments'? -

i have set pundit devise authorization on application. in 1 of controllers, have before_action :authorize.

i have following test:

describe somecontroller   before(:each)     login_user(factorygirl.create(:user, :user_type => :admin))   end    describe "get index"     "it retrieves index"       = factorygirl.create(:something)       :index       assigns(:something).should eq([something])     end   end end 

i receive error:

wrong number of arguments (0 1) 

the login helper straight forward:

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 

update: stacktrace:

pundit's authorize method not intended called before_action. before_action calls method no arguments, , authorize takes model object , optional permission name. that's why you're getting error are.

you're not showing enough of relevant code me see should next, suggest getting pundit work in controller action before pulling out callback.

there example of correct use of authorize here: https://github.com/elabs/pundit
